My girlfriend is buying a Pentax K-5 (I already have a Pentax DSLR so we thought it made sense for us to be able to share lenses), and she's not sure about which lens to get with it, so I've been charged with offering her my advice/research.

We left it last night that I'd ask here for advice on which superzoom to get (e.g. 18-200mm Sigma) as they would be very convenient, but, as usually happens when I start reading and researching, my targeted level of quality took a significant bump and I'm now thinking that if she's spending that kind of money on a prosumer body she may as well stick to the kinds of lenses that will help her get the best she can out of her camera. She's often examining the sharpness of her photos and is a bit of a perfectionist, so I think she'll enjoy her photography more overall if she knows she's not being held back by her lens, even though she'd have to swap over to my SMC Pentax-FA 80-320mm f4.5-5.6 when she wants telephoto.

Photography is a hobby of hers (neither of us are pros or anything like that). Normal usage will be landscapes, nature, friends/family shots, holidays.

As this prime would function as her general walkabout lens, I'm looking at focal lengths of around 35mm. One which has caught my eye is the SMC Pentax-DA 40mm F2.8 Limited.

From what I've read, the quality is good and having a pancake lens would be relatively portable and pretty damn cool. :)

Possible points for considering others:

  • She sometimes likes to get in close with flowers, etc., and it's not a macro lens.
  • I gather f2.8 is decent but that larger apertures on primes are relatively available.

It doesn't have to be Pentax as long as it fits her K-5. (She's German so I'm sure she'd be up for a Carl Zeiss, but I expect they're way more expensive.)

Her budget seems to be around €450ish for the lens, but I think she's open to moving slightly either way depending on value.

With that in mind, do you have any advice, recommendations of specific lenses or general guidance?

There's so many nice Pentax primes — why pick just one when you can collect a whole set? That's why we have Lens Buying Addiction, after all!

In seriousness, based on what you've said, I think the smc PENTAX DA 35mm F2.8 Macro Limited may be the place you should start. But, I've used quite a few Pentax primes, so let me give you the whole tour, as it were.


Pentax makes two major series of prime lenses, and a number of prime lenses outside of those lineups as well.

FA Limited is the premiere prime lineup from the last days of Pentax as a film camera company. They're relatively modern designs (dating to the late 90s and early 00s), but definitely made for film. Manual focus on these lenses is a pleasure, and in exchange autofocus is a bit slow. In general, they have gorgeous rendition, and are relatively fast and small. Presumably the lens coatings are not designed for digital sensors, but I really haven't seen anyone complaining. The lenses have full-frame coverage, and there's persistent rumors that Pentax is going to cancel them any day now — but they haven't yet. (For a while, they weren't even shown, but they're back on the Pentax lens roadmap now.)

DA Limited is the designed-for-digital premiere prime series. The design focus is somewhat different: small, jewel-like "pancake" designs are favored, and even the models which aren't technically pancakes are quite compact. This is at the expense of a few stops in max aperture, the thinking apparently being that the amazing high-ISO capabilities of modern sensors make this less important. They do generally have nice bokeh, although maybe a little busier than that of the FA series. And a key point is that they're quite good wide open — you can get peak performance by stopping down a bit, but you don't need to. Autofocus is very fast (another advantage of keeping the weight of down), and while they feature solid metal construction, the focus rings have less throw, which, combined with the slower optics, makes manual focus not as enjoyable as with the FA series. Overall, the optical qualities are excellent, and while the FA lenses have legendary status, the DA lineup is by no means a step down.

In 2013, Pentax announced a refresh of the five lenses in the DA Limited series, adding curved aperture blades and the improved "HD" optical coating. These versions have a red ring instead of the green ring found on the earlier models. The previous SMC coating was well-regarded, but theoretically these should have higher transmittance and even better control of flare and ghosting, and of course more attractive bokeh when stopped down. It's a pity they didn't add weather resistance, but that probably would have meant a significant redesign of the lens body.

DA ★ (or DA Star) is Pentax's "high grade" designation. Lenses in this series are weather- and dust-sealed, and feature ultrasonic focus motors built into the lens. There's a few long telephoto lenses with this designation, and one portrait prime.

Then, there are a few other lenses in production within the DA, FA, and D FA series. In general, the ones with a D are designed with digital in mind, and the FA means full-frame coverage. Up until recently, it was sure that the D FA models had a manual aperture ring, but Pentax doesn't seem to hold that sacred.

There are also a lot of out-of-production lenses that are worth looking into, from the FA series and older. But in the interest of this-is-a-long-enough-post-already, I'll going to concentrate on only current models.

So, on to specifics:


smc DA 14mm F2.8 This is one of the older DA designs. I've only used it briefly in a store; my main impression was that it's relatively large and heavy. It's, basically, what you might expect from a fast ultrawide prime. I haven't really heard anyone raving about this lens one way or another.

smc DA 15mm F4 ED AL Limited / HD DA 15mm F4 ED AL Limited I just got this, and, apart from struggling with wide-angle composition in general I really enjoy it. It's inevitably heavier and a bit bigger than the other DA Limited lenses, but still feels compact. The old-school distance scale on the lens is a nice touch, and the built-in lens hood is great. I don't really miss faster apertures at this focal length; generally I want more in focus, not less, and I tend to use it where there's plenty of light. Perspective distortion is inherent with ultra-wide, but barrel distortion is impressively controlled, and there's no other strange distortions or any optical problems to speak of. And for a wide-angle lens, it does an amazing job of handling flare — you can point this thing right at the sun and get nice results. Recommended, but probably not as your first starting point.


smc DA 21mm F3.2 AL Limited / HD DA 21mm F3.2 AL LimitedMy friend from whom I could borrow this moved to the other coast a couple of years ago, so I'm going from memory. My main impression was: yeah, that's fine. It's not dramatic enough to really feel wide, but it takes in enough of the scene that it doesn't feel intimate. However, the field of view on a 1.5× crop-factor dSLR like the K-5 is roughly equivalent to the traditional 35mm, which I know some photographers really like. So if that's your thing, this may be a good choice for you. (Having used the iPhone camera extensively, I think I have a little more appreciation for the versatility of a moderate wide angle lens like this than I did; I should give it another try.) As with the 15mm, I don't think the speed is generally a concern, not with good high ISO from the camera.


smc FA 31mm F1.8 Limited I have not used this lens, but it is certainly legendary among Pentax photographers. Since I haven't direct experience, I won't go on, but people do love it. This is the third-most expensive lens Pentax has on the market, which, at less than a $1000, is really another way of saying that Pentax's great lenses are really quite affordable, comparatively speaking.

smc DA 35mm F2.4 AL This is Pentax's new affordable normal prime, their answer to Nikon's AF-S DX Nikkor 35mm f/1.8G. It's a decent lens, and rumor has it that it's basically an update of the generally-respected smc FA 35mm F2 AL, which was recently discontinued. Plastic construction, but solid. There's a few other cost-cutting measures — for example, no "quick shift" to disengage the focus system when AF isn't active, which I think is a nice feature to have. Image quality doesn't stand out particularly, either positively or negatively. I think it's a decent value at the price, but I also think it's probably not what you're looking for. (It's a better match for the K-r than the K-5.)

smc DA 35mm F2.8 Macro Limited / HD DA 35mm F2.8 Macro Limited The main reason I don't have this is because I have and love the 40mm Limited, and I decided that they're too close to justify it. I came close, though! I've seen some technical reviews which conclude that the numbers aren't as good as those for the other Limited lenses, but the actual results I've seen are stellar. Lens connoisseur Mike Johnston puts it through some hands-on testing and ends up calling it "an optical paragon", which is really better than taking my word for it. Compared to the DA 40mm, the slightly wider field of view makes it closer to a true normal lens on the Pentax DSLRs (although even wider would be ideal — around 29mm). One downside is that since it's designed for macro focusing, the AF is somewhat slower than on the DA 40mm. The K-7 or K-5 can still focus it quite quickly, though.

smc DA 40mm F2.8 Limited / HD DA 40mm F2.8 Limited This is my most-used lens. (I posted a bunch of sample family snapshots in the photo chat a few weeks ago, and there's one in the official Pentax Photo Gallery, which I'm kind of proud of because that site is very unfriendly to posting pictures of your kids.) From a technical standpoint, it produces gorgeous results basically effortlessly. And I'm pretty sure it's the fastest autofocusing of any Pentax lens. The focal length is a bit odd on a 1.5×-crop camera, but it basically works out like a normal lens with a built-in crop that makes you make tighter compositions without thinking about it. It also has a close-focusing distance of about 13", which is not macro by any means but lets you get comfortably close to things if need be. Anyway, this stays on my camera 80% of the time. One tip: stow away the screw on lens cap and replace it with a clip-on one. The metal lens cap is classy, but too fiddly for field work. (If you have a Pentax Auto110 by any chance, the cap from the 35mm lens fits perfectly, and still says Pentax. Heh.)

smc FA 43mm F1.9 Limited A friend of mine got this at the same time I got the DA 40mm, so I've been able to compare pretty well. Stopped down, the results are pretty similar; of course, the FA 43mm is slightly more than a stop faster, and the bokeh definitely is nice. At f/2.8, the DA 40mm lens is sharper across the frame, while the FA 43mm is distinctly sharper in the center. The FA is much slower to autofocus, to the point where I'd sometimes miss things I know I wouldn't have with the DA 40mm.

Portrait Telephoto

smc FA 50mm F1.4 This is the classic film-era nifty-fifty from Pentax. The FA design comes directly from the earlier models with F, A, and even M designations, and probably even before that. It stacks up just fine against similar lenses from other brands, and again, Mike Johnston likes it. However, it's a bit, I dunno, pedestrian compared to many other Pentax primes. At the current pricing, I really don't see why one would go for it over one of the Limiteds, unless f/1.4 was really, really important to you.

smc DA 50mm F1.8 Pentax's newest lens, but from the optical specifications, probably a refresh of the classic 50mm f/1.7 — which is no bad thing, because that's a wonderful lens (also on Mike Johnston's top 10). I have the old version, and it's my favorite lens on my K1000 film camera. The new version adds modern conveniences like autofocus, newer optical coatings, and features rounded aperture blades for smooth bokeh — just like the much more expensive DA ★ 55mm below. Like the 35mm f/2.4, this is positioned as a budget prime, but as with that lens, the skimping seems to be on things like plastic lens mount rather then metal — not on image quality.

smc D FA 50mm F2.8 Macro Another older design, with solid but plasticky construction. It does have the quick-shift mechanism like the DA lenses, so you can manually focus even with AF engaged. Like most macro primes, it features excellent optical quality, but sometimes people complain about the octagonal highlights when stopped down. Also, on APS-C, this becomes a kind of weird length for macro. The wider 35mm works better as a general-purpose lens (or for document reproduction), and one of the other choices is probably better for portraits.

smc DA ★ 55mm F1.4 SDM As far as I can tell, people fall into two camps on this lens: people who have read technical reviews and hate it in theory, and people who have used it for portraits and love it in reality. This is a special-purpose lens with a modern design specially made for portraits. It's got Pentax's quiet but slow USM focusing system, a non-rotating front element, and all the high-end touches one would expect of a ★-class lens (including dust/weather sealing). The aperture blades are rounded for smooth bokeh, which is nice because while it's designed to be used wide open that gives flexibility to stop down a bit as well. And, it's one of only a very few Pentax lenses to use a nanocoating, which they call Aero Bright. It's also heavy and and quite a lot more expensive than the FA 50mm F1.4. If you're really serious about making photographs of people and don't give a second thought to the weight, definitely consider this.

smc DA 70mm F2.4 Limited / HD DA 70mm F2.4 Limited I have this lens and use it often. It pretty much never goes wrong. It's not as tiny as the DA 40mm, but is still incredibly small and light. Despite the diminutive size, there are basically no technical flaws or problems which impact image quality. Like the DA 15mm, it's got a handy built-in pull-out lens hood. The focal length is just right for close-in portraits, but I've also used it for kids' soccer games. Because of the small size and weight, this is one of the fastest focusing options.

smc FA 77mm F1.8 Limited As with the DA 40mm / FA 43mm Limited, I've had some time to compare against a friend's copy. The FA 77mm is a little bit faster in terms of aperture, and it's reasonable to argue that the bokeh has a more dreamy quality. The 70mm is a bit sharper across the frame, although for the kind of work one would usually put it to, I don't think that's a serious complaint against the 77mm. Also, as with the 40mm and 43mm, the newer DA lens is decidedly snappier to autofocus. The FA lens is quite a bit more expensive, and overall the results are quite similar — I don't think most people could tell the resulting images apart in a double-blind study.

Long Telephoto

smc D FA 100mm F2.8 Macro See the next entry.

smc D FA 100mm F2.8 WR Macro I have to insert the caveat that while I've at least handled most of the lenses above (and used a number of them quite extensively), I've never even touched the 100mm macros. So, I'm going to restrict myself to more general comments. These are basically the same lens; the WR version is newer and features a Limited-style metal body with weather sealing. Optically, they're the same, and quite well regarded. There's some hope that the WR designation will find its way to a newer version of the 35mm Macro as well, since a weather-sealed normal is conspicuously missing from this list.

smc DA ★ 200mm F2.8 ED (IF) SDM I was able to use one of these for a couple of weeks as part of the Stack Exchange Gear Grant Program. This is a great lens with beautiful rendering. Construction is top-notch, and like all ★ lenses, it's weather-sealed, so it could be part of a nice wildlife kit. However, wow, it is large. It is literally larger and heavier than all my DA Limited lenses put together. Personally, I'm not sure I'd go Pentax in the first place if this sort of lens was my attraction, as the big two camera brands provide even more options in this range — and up. But if you're invested in Pentax for other reasons and this is something you need, it's good that there's the option.

smc DA ★ 300mm F4 ED(IF) SDM Basically a twin to the 200mm DA ★, announced at the same time and with similar construction. The 300mm has the distinction of being the second most expensive current Pentax lens, bested only by the smc DA ★ 60-250mm F4 ED (IF) SDM weather-sealed zoom. I haven't used this one but by all reports if this is the kind of lens you're looking for you won't be disappointed.

The Pentax Limited 35mm F.2.8 Macro, as suggested by @rfusca, would be my first choice considering your description. This lens is really great and takes fantastic close ups. I own one and it happens to be my wife's current favorite.

You are absolutely right to stay away from the super-zooms, the quality is much lower and if you appreciate seeing sharp images, you will be much more satisfied with a high-quality lens either prime or high-end zoom.

My favorite Pentax prime is the 31mm F/1.8 Limited which is the sharpest lens I have ever owned, followed closely by the DA* 55mm F/1.4 which is also awesome but too narrow for me to use often.

There is also the Limited 77mm F/1.8 which is legendary for portraits. I am still waiting to add it to my collection.

All the lenses I mentioned already are spectacular. There are a few more in the Limited series which I found not such great values and sold mine after a year or so, like the 43mm F/1.9 (too soft wide-open, by the time you step down, you should have bought the 40mm instead) and 15mm F/4 (the DA 12-24mm F/4 zoom performs better than this one).

I know a lens has been purchased already, but just wanted to mention with the Pentax, if you don't mind using manual focus, there is a wide catalog of older lenses you can mount on which meet, and sometimes even surpass the quality of even current production lenses.

The Takumar series by Pentax has a strong cult following and a rich history; great place to start. I love primes, and I'm happy you decided to go with one :) You can learn a lot from them, great dexterity builder. These lenses can usually be found on craigslist or old camera shows.

You also don't have to stick with the k-mount, if you grab a m42 to k adapter, you can also start grabbing some m42 zeiss glass, or zeiss copies, like the sonnar 85/2 copy: jupiter-9 85/2.

I'll also go ahead and suggest you bookmark this now: bdimitrov.de/kmp/ Dimitrov's site is a great reference for older Pentax glass.

Enjoy your Pentax mate, and I really hope you start prime huntin'

When choosing a prime it helps to really know what the primary use of the lens will be. You have a pretty wide range of uses listed there: landscapes and nature but also some portraits and wildlife and perhaps some macro. All those situations don't say prime to me - they say zoom.

So, I'd determine what's more important - the quality of a prime balanced by the more limited range, or the versatility of a zoom with a drop in quality (assuming she would want her own zoom, that is).

Some alternative primes are:

  • For landscape/travel photography: Sigma 30mm F1.4 EX DC HSM
  • For portraits, nature and macro: Pentax smc DFA 50mm f2.8 Macro

Sigma also do a very well-received VR superzoom with a Pentax fit, namely the Sigma 18-250mm F3.5-6.3 DC OS HSM.

  • \$\begingroup\$ Thanks a lot for the advice. The 18-55mm kit lens is only €60 more when bought with the K-5 body, so she said she'll buy that to use to start with. She's now planning to subsequently look at buying a prime or another zoom. \$\endgroup\$ Jun 29, 2011 at 19:47

If you're after a very decent lens in the 35mm range, you must seriously consider the Pentax SMC DA 35mm f/2.4 AL. A review is available here.

It's a very good and affordable lens, and I've thoroughly enjoyed using it on my K-5.

  • \$\begingroup\$ Thanks very much - sounds like a good, slightly less costly alternative. \$\endgroup\$ Jun 29, 2011 at 20:19

I'd consider the Pentax SMC Limited 35mm f/2.8 DA Macro. It's razor sharp, good build, covers the focal range that should be useful for you, and will allow you to get in close for that flower macro shots that she likes. The biggest concern is probably the fact that there's a good amount of focus ring travel for an everyday lens - but it doesn't sound like she's shooting anything action oriented, so it wouldn't be a major concern for me.

With the K-5's superb high ISO, a lens that maxes at 2.8 wouldn't be too much of a concern for me unless it was intended just as a portrait lens.


One of the best things about the Pentax line is their small collection of "pancake" primes: These are very well made, optically excellent and tiny, tiny lenses, and they render the K5 barely bigger than many point-and-shoots. These lenses are lightweight and small enough to stash in a jacket pocket. I've owned 3 of the 4 at one time or another (and one day I'd like to get my hands on the 15mm, as well), and my hands-down favorite of the three is the 21mm. On the K5's ASPC sensor, this is (approximately) equivalent to 35mm, a great walking-around lens, great for street photography, landscapes, etc. It's not very fast (f/3.2 wide open) but with the K5's sensor, I've never found this to be a problem. The 40mm is also a great lens (and substantially smaller than the 21mm), as is the 70mm... but for me, it's the 21mm that wins, hands down.


As it seems that too many great lenses are missed, let me help you out there with the remaining prime lenses you should consider looking after

smc FA ★ 24mm F2 AL(IF) Also another old lens from the end of the film period. This lens was released in 1991 and is reputedly designed by Jun Hirakawa, and built as one of a series of no-compromise pro lenses of the late film era. Oprically a bit soft, or at least slightly glowy wide open, especially if the light is contrasty, and the corners don't match the center until about f5.6. It can produce some pretty nasty purple fringing towards the edges.

The f2.0 mades it very fast for an ultra wide angle lens and it makes the FA ★ 24mm F2 the fastest ultra wide angle lens (24mm or less) ever made by Pentax.

You can check what users believe about it in here

smc F 50mm F1.7 Another older design, with solid but plasticky construction. This lens is based on the M version, the M 50mm f1.7 but it has an auto-focus motor. Colours are typically Pentax and you'll notice that when using it. It produces nice colour images, crisp and clean. This is a lens on a budget compared to the other ones stated above. I have it and its very nice to use and creates wonderful portraits. Please check the Pentaxforums opinions on this lens to get an idea about what do users think about it.

smc FA* 85mm F1.4 Another older design, with solid construction. No plastic was attached here. You will notice it because of its charasteristic colour, as this FA* lenses are painted in light grey and you can see the Pentax name painted in black. Those lenses where the best lenses the brand was creating at the late era of film (mid-late 1990's) and their image quality is exceptional. Link to the owners opinions to be found here

smc DA ★ 50-135 F2.8 ED (IF) SDM This lens was introduced in 2007. On a APS-C body is the equivalent to a 70-200mm in a Full Frame body. It is known to have issues with the SDM motor that uses to fail. This lens is also convertible by software to screwdrive mount and this will usually solve the AF stop working once the SDM motor fails. It is also known the quality of the images that this lens produces from f2.8 on the whole range. This is a great lens for portrait photography or wedding photography, it has a very versatile range and is a fast lens able to produce a very nice pleaseant bokeh at apertures around f2.8 or f4. You can see more opinions here

smc FA ★ 200mm F2.8 ED (IF) Another classic lens, with a great construction. Again this is a lens made in the latests days of film and was created to be used by professionals. I have it and this is the best portrait lens you will ever imagine. Many say is the best 200mm lens ever produced, not only for Pentax but for any brand. The images this lens can take are stunning and without a doubt if you need a lens for portrait, modeling or studio you need this lens. It is small and compact. You will also notice it because of its light grey colour and the Pentax characters in black. Probably better or at least in pair with the DA Star 200mm lens. Again more opinions to be found here

smc FA ★ 300mm F4.5 ED(IF) Basically this is the twin to the FA ★ 200mm but this lens is not as fast. Its maximum apperture is 4.5. The good thing about this lens before the DA star lens is that it does not use the SDM engine, so you will never find that as a problem. Again is a great portrait lens and in many cases great for studio photography. As any FA Star this lens is grey with the Pentax logos in black. Link to the owner's opinions to be found here.

smc F ★ 300mm F4.5 ED(IF) Again an old design lens from the end of the film era. The F Star was released in 1987 and was Pentax's first Auto-Focus 300mm lens and was replaced by the FA ★ 300mm in 1991. The F Star is a sharp and small lens. It doesn't look like a 300mm by the exterior size. That mades it easy to carry around because is not heavy. You will recognize it easily because of its white paint and the Pentax logo in light grey on the cap. This is a great lens for wildlife photography. I personally have tried it (borrowed from another Pentaxian) and found it light and small for a 300mm lens. It focuses quite fast and delivers great quality images. One more link so you can have your own conclusions based on owner's opinions.

There also exists 400mm DA Star lenses, and others but I consider them to be very specific kind of lenses for some very specific kind of images so I am skipping them.

You will also notice that there exist a FA* Zoom that is the FA* 80-200mm lens.


Just returning to Pentax, there are a handful of lenses I've found superb (going from wide to tele):

DA 15, Tamron SP 10-24, Tamron SP 17-50, DA 40, DA 70, DA* 50-135 (newer version, older have had problems with bad SDM motors, that are prone to fail, also used in the DA16-50, I believe), Tamron 70-200/2.8. Sigma is good at macro lenses, their 150/2.8 having no peers, at any cost! For a small kit I'd say DA 15, DA 40, & DA 70,


A very nice summation of great Pentax optics! As a Pentaxian with experience with a few of the lenses mentioned, I can vouch for the superb image quality of the following, in no particular order: DA* 55mm f/1.8, DA 70mm f/2.4 Limited, DA* 16-50mm f/2.8. In addition, while perhaps a step below the aforementioned lenses in terms of build and image quality, I can still recommend the DA 16-45mm f/4 as an inexpensive general-purpose zoom. It's quite good, for the money!


http://www.pbase.com/wes I have the K20 and the new K5 the lens I use most of the time for landscape shots is my 16-50 2.8 lens and the 50-135 2.8. I can recommend either one of them. I did have some problems with the 16-50 but Pentax replaced it with a brand new one which I have for several years now. I also got the 40mm 2.8 which is very sharp and light and great for walking around and not having to carry all that weight.

The pitures below were taken with the 40mm lens
