Who in the world buys large primes? Wildlife and sports photographers, mostly. I'm struggling to see how one would find use in a long focal length prime, 300mm and above for example: without zoom, isn't your shot composition always at the mercy of how close or far away your subject is, meaning heavy cropping is almost always necessary in post? ...

The focal length is the distance from the (theoretical) center of the lens to the image plane. On the large format camera, there's a lot more camera between the lens and the film. The lenses are also often relatively simple — there's no need for a focusing mechanism in the lens itself, for example. @osullic gives the example of the Schneider PC TS ...

You are seeing chromatic aberration — a prismatic effect which, as you nicely illustrate, reduces sharpness even in black and white photography. A lens which has greater correction for this is called an apochromatic lens — often something like "APO" in the lens name. Note that in lenses for telescopes and microscopes, you'll often also see achromatic ...

I have found these lens Nikon AF 70-300mm f/4-5.6G in a very good price. I am planning to use them mainly to take pictures of the moon. I am aware that this lens does not have image stabilisation. Is this a major drawback ? If you plan on shooting a full moon on a clear night, handheld, it shouldn't be, because you can easily get shutter speeds faster ...

Field of View The sun is approximately 0.5° across in the sky. At 200mm on a DX (1.5 crop factor) body, the field of view (FoV) is 6.9° (wide) / 4.5° (high) / 8° (diag). In terms of Sun diameters (☉), the 200mm FoV is 13.4 ☉ wide by 9 ☉ high. According to Wikipedia, Mercury's diameter when viewed from the earth during May transits is 12 arcseconds. In ...

35mm is not wide enough for many types of general photography. With any group shots, (especially indoors) or any large outdor landscape scenes, you will need something like 16mm to 18mm to get everything in the frame. The easiest way to accomplish this is by going with the 18-55mm kit lens. I don't know what you read but todays kit lenses are much better ...

How can I modify my NIkon D5500 so I can make a vintage lens auto focus? You can't. I learned that using a TC-16A AF Teleconverter 1.6X might help ... Whatever you learned is probably wrong. From my googling it looks as if the TC-16A was designed to turn AIS lenses into AF lenses (i.e., an interim step to add electronic communication and the ...

It depends. This is why getting a blanket lens recommendation almost never works. Everybody has a different set of priorities on what and how they want to shoot and how much they have to spend. Getting a 35/1.8 and a telephoto could work really well for you. It also might not. Whether or not you "need" the kit zoom depends. The main thing to keep in mind ...

Probably not. But it depends on just how dark and what type your ND filter is. It can be very dangerous to both your equipment and your eyes to try and take photos of the sun without the proper precautions! The most damaging portion of direct sunlight to the internals of your lens, camera, and eyes are in infrared, not in the visible spectrum. The UV filter ...

If you use a tripod, image stabilisation is not necessary. If shooting hand-held, image stabilisation can become important. Given the rule of thumb that 1/focal length is the longest hand-holdable shutter speed, that you likely want to use 300mm and that you likely take the image at night, chances are you have to pick a higher ISO value to keep the shutter ...

The only guarantee is that a DX lens will throw an image circle approximately large enough to cover a DX sensor. Some throw them a bit larger, but the only way you'll know if a given lens does that or not will be to try it. Carrying your math a bit further, the DX diagonal is 0.12mm smaller than that of the AX100. The pixels on that sensor have a diagonal ...

Yes, it's possible — but it's more likely that that's just how it is. You can't expect miracles from a point and shoot camera, and fine detail with no noise when "pixel peeping" would be a miracle. You say that the results are satisfactory for viewing as a whole on a computer screen. They'll also be fine when printed at reasonable sizes. In any case, it's ...

Dirt can never cause grain. It's more likely you are seeing digital noise. Switching to lower ISO should help.

You might buy one in order to get a balance of high quality, reasonable size and weight, fast aperture, and a lower price. As you say, people often get shorter primes because they like a particular field of view, and I don't think that's usually the case beyond, say, 90mm (in 35mm terms). That list of compromises can't be avoided — but giving up zoom lets ...

The Minolta Hi Matic 9 has a fixed 45mm lens. It is not possible to switch lenses. Source: oldcamerareview Lens variety and interchangeability – Nope, you won’t get that either. But, if you are the person that had to save up and finally got your Leica and lens, you probably can’t afford another lens for awhile anyway.

The Nikon AF 70-300mm F4-5.6 ED D was a fair lens back in the day, but the problem you'll have now is that it's not an AF-S lens -- meaning it doesn't have an autofocus motor built in -- and will therefore be manual-focus only on the 5300.

Yes, the two letters together mean High Definition. It is just a marketing term like many others. Pentax at some point changed the coatings on 5 of their lenses and added HD to their names and changed a color around the edge from green to red. You will find the press release for the coating here. There is a copy of the press release for the lenses here. ...

portrait, landscape, macro If these are the kinda of photography you intend on doing then maybe the kit lens is the better choice over the 35 prime. I assume you are going with the 55-200 regardless so the debate really comes down to the 35 prime V.S. the kit lens on a D3300. I happen to own both the kit lens and the 35mm on my D3300 so ill discuss some ...

Take a look at these two Schneider lenses that both have 90mm focal length: The first has coverage for "35mm" format, the second coverage for large format. I am not sure, but I think the main reason for the difference in size is the fact that the large format lens is a "simpler" design, i.e. fewer elements/groups. The reason a large format lens can use a ...

Can any of you tell me which would one be preferable for landscape photography? The slim one is slimmer, which means that there's less chance of the edge of the filter being visible in images taken on a wide angle lens. An 11-16mm lens is certainly wide enough to justify a slim filter on a full frame camera, but since your 550D has an APS-C sized ...

The camera lens is a converging lens. Light rays from the subject enters the lens and the lens, due to the shape and density of the glass lens, emerge tracing out a revised path. This path resembles a cone of light. We focus the camera by moving the lens forward or backward. This action adjusts the position of the apex of the cone. We want the apex to just ...

Yes, the 18-55mm lens will of course also do 35mm. This focal length determines the angular field of view of the lens. So the 18-55 is more versatile in that way. Because 18mm is a 2x wider view (than 35mm), which is called wide angle, and 55mm approaches a magnified or zoomed in view, of about a half again larger subject (in a smaller zoomed view than the ...

I would say you want a telephoto lens. If you want a scan-like image, being far away with a long lens is your best bet, as it will preserve the rectilinearity of your subject. I don't know exactly how long a lens you'd need to get no noticeable distortion, but if it were me I would use my 100mm prime. Edit: another option would be to shoot with a wide angle ...

If the lenses are not currently made to mount on Nikon DSLR bodies (i.e., Nikon F-mount), then no, you probably cannot buy an adapter to use them on your Nikon body. The reason for this is that Nikon's F-mount has one of the largest flange focal distances (also known as registration distance) for currently-available DSLR bodies on the market. I believe your ...

Do you have "Auto Dx crop" enabled? If so, try disabling the "Auto DX crop" setting. Photo Shooting Menu > Image area > Choose image area > Auto DX crop. Change Auto DX crop to Off (if it's On). You can still manually change the sensor area between Full and DX, and even assign that setting to a quick menu setting so it is easier to access. As Mike Sowsun ...

I have several answers. 1) Use whatever lens you want (or can). You are limited not by a lens, but on the actual space you have in front of your board. If you have the board on a tight space, you will probably need a wide angle lens, but if the board is on the middle of a manufacturing plant, you can use a telephoto lens to minimize spherical distortion. ...

Keep the 18-55 IS II and 55-250 IS. The 1200D is a stripped down budget camera bundled with striped down budget lenses. The lenses that came with your XSi are actually superior to the the 1200D kit lenses. The 18-55 III has the same optics as the 18-55 IS II but lacks Image Stabilization. The 75-300 USM has poor optics and lacks Image Stabilization. ...

With the 70-300mm, I guess I could take pictures of the moon or any other close up objects 300mm doesn't really get you close enough for the moon. You could use a teleconverter, but you'd either have to get a third party one or make warranty-breaking modifications to a Nikon one. However, you can get some nice wildlife pictures at 300mm, particularly ...

This depends on the make and model of lens. But often 'HD' means it is specifically designed for recording HD video. So features will often include: power zoom fast focusing, and focus tracking image stabilisation smooth aperture changes quiet operation Not all of these features will apply for every HD lens. Though optimised for video, some of this ...

Might also have to do with speed. Some zooms are limited in their range, being slower at longer focal lengths. Take a look at photographers on sidelines of football matches; they might have one long fast zoom and then a shorter lens on a second body in case the player gets close. They are, however, specialized lenses. Usually for situations where you are ...
