So, there a couple of basics to get out of the way first. Pentax DSLRs are just fine compared to Canon and Nikon; they're solidly built, have a decent but smaller following, and in fact often have better features at the same price level (because they need to, to compete). That's not to say blindly that "Pentax Is The Best!"; in fact, they're all great and ...

I started out much the same way, choosing Pentax DSLR because I already had Pentax lenses. While I'm still with Pentax (now on my 3rd: ist-D; K-10D and now K-5), to be honest I barely ever used my original lenses. Absolutely no offense intended but your existing lenses don't look anything particularly special, just as mine weren't - they look perfectly ...

I'm far from an expert on Pentax legacy lenses but the kit you have doesn't appear to be anything I would let drive future purchases. In other words, unless you have a strong personal tie to the equipment or are working with a very limited future budget, I would recommend not adding in those lenses to the equation. As for the statement "Pentax DSLRs aren't ...

Just swap out the ink cartridges as needed. Note that there will always be some remaining ink in the pipes, there is no way around it other than getting a second print head, and if you do that you may as well get a second printer. If most of your print work is documents I suggest getting a laser printer. You can get a monochrome laser printer for well under ...

Focusing solely on the question of focal length: a football field is about 160 feet wide. Simply assuming you're on the edge of the field and the graduate is straight across on the other side, assuming you're using a full frame camera you should be able to get a fairly tight shot of the individual with a 2700 mm lens (on a 1.5x crop camera you would only ...

I think the practical answer here is "nothing that you'll be allowed in the stadium". Any lens long enough to pick out the details you're looking for is going to be so big that it will annoy other members of the audience. This goes doubly for any suggestion of using a tripod.

Image sharpness is more a function of the lens than the body. The Canon 60d and the 24-105L F/4L are both capable of shooting stock-acceptable imagery. I used the 24-105 as my wide angle lens for a while and I really like it a lot. In the case of the pelican image, the focus seems to be on the wall between the two pelicans on the right, not on the ...

You need to buy a lens that is Canon EOS compatible. Canon EF or EF-S lenses will work with your camera. Many manufacturers create compatible lenses also, Sigma makes a compatible lens with good quality at a reasonable price.

Both Canon 1.4x and 2x extenders work - more information here (search within the page for extender). Additionally, fitting this on a 1.6x crop-sensor body will give an equivalent of 38.4mm focal length. This route would avoid the incorrect aperture reporting issues, and potentially offer better image quality than when using an extender - if you happen to ...

The self-timer on a Canon dSLR has two options, 2 or 10 seconds. 4 seconds is an unusual delay - are you using Live View mode by any chance? That would account for the delay as full Live View focusing is much slower than in non-Live View modes. Putting the camera in normal non-Live View mode, setting the AF mode to One-Shot and drive mode to Single should ...

No. It will not work as a master off-camera. None of the Canon flashes can be used simultaneously as a slave and a master. The 90EX is only a master unit if used on the hotshoe, or tethered off-camera with a TTL cable. If used on manual-only radio triggers, there's no way for it to sense it should perform master communication. And TTL radio triggers act ...

Canon now makes two pancake lenses for the EOS mount. Both are just slightly wider than "normal", f/2.8, metal builds, and come with the STM focus motor. Both have reviewed quite well for sharpness and overall image quality; see the-digital-picture.com reviews for the 40/2.8 and the 24/2.8. The EF 40mm f/2.8 STM is for full-frame cameras. The EF-S 24mm ...

There's an interesting thread here on Reddit. The best comment is from the owner of fdtoef.com where they say: The first challenge is how to keep the adapter on the FD body, a lock like the FDn lenses. The FDn is too complicated for that amount of space, so it would need to be the original breech-lock approach. Assuming that the body FD mounting was ...

According to the manual (specifically, page 96) this is not possible with the Canon EOS 450D. However on page 97 there is this information: If the [Custom Functions (C.Fn)]’s menu [Auto Lighting Optimizer] (p.156) is set to [0: Enable], a darkly-exposed (set with exposure compensation) image may be displayed brighter. This might help where your ...

On the Canon website, look under 'software' rather than drivers. Download and install the Canon RAW Codec 1.11.0 Alternatively, you can try FastPictureViewer, which is a 3rd party codec pack that support lots of raw file types including Canon. It also supports PSD, which is nice as well if you use Photoshop. There is a trial version to try, otherwise its ...

The lenses that will work with your camera will be denoted as EF or EF-s (e.g EF 50mm f/1.8, or EF-s 18-55mm f/3.5-5.6 IS II) if the are Canon or as "For Canon EF" or "For Canon" for other manufacturer's lenses, such as Sigma, Tamron, Zeiss or Samyang. EF-m lenses will not work properly on your camera, or any Canon DSLR. Likewise the EF-s lenses will not ...

Lots of factors at play here. Know what the lighting will be like will be very hard to know ahead of time. Professional sports photographers use large aperture zoom or fix long focal length lens that can cost several thousand dollars or more. Depending on the cameras abilities, you'll probably need to set your ISO up pretty high, your aperture very ...

I agree that was an awesome technology but only to the beginners I suppose. And even thought it was very popular among a mass crowd it had a few setback: It had to be calibrated with the eye of the user, which worked out easy for many but not everyone. If a picture had to be clicked using ECF, the user must focus his eye on a particular place, and many ...

Yes. Just make sure that you buy the Canon mount version for this lens, as third party lens makers generally also make versions with mounts for Nikon and other camera brands.

My guess is this is a gap in the reverse engineering Yongnuo does for the electronic communication protocol of the Canon hotshoe. The AE-1 is old enough that it's using the film version of TTL/A-TTL, while the Rebel 2000 uses E-TTL, and the T1i uses E-TTL II. Canon flashes can probably detect and switch to the different modes for TTL/A-TTL, E-TTL, and ...

If it's low-light work you're primarily intending to do then the f2.8 lenses are a better option as they are an f-stop brighter than the Canon 24-105 f4L. Image stablisation can only do so much and having a wider aperture will give you a head start in low-light environments, making IS less necessary. Also bear in mind you're less likely to need IS at wider ...

Coming from a 5D mkII, the 1Ds mkII will be an big upgrade in terms of the number of autofocus points and the robustness of the body (which is fully weather sealed), but a downgrade in pretty much every other area, such as resolution, noise performance, video (non-existent), LCD screen (tiny, low-res and poor daylight visibility and viewable angles), ...

There's technical information here about the various substitutes available that give you more options. The page lists several substitutes with information about availability as well as technical information regarding voltage stability.

Canon teleconverters won't fit because they have a protruding front element that needs a corresponding recess in the host lens, which only the Canon L-series teles have, but third-party ones from Tamron and others should fit. Not Sigmas, they have similar design to the Canons. Optical quality is another matter, it is usually desireable to stop down a bit to ...

Using a teleconverter on a a Rebel body with a slow zoom lens is not likely to work well, unfortunately. Autofocus will not work and image quality is going to be poor. You are much better off saving to buy a longer lens.


1

Short Answer: Yes. All EF and EF-S lenes are compatible with your 7D. You should not have any autofocus problems if camera and lens work well. Otherwise you should check the lens on an other eos (if you can) respectively the amera with other lenses.

The lenses you have all appear to use the original Pentax K-mount. Modern Pentax cameras lack the mechanical stop-down coupler the K-mount lenses were designed for, meaning the camera cannot detect the lens's aperture setting, limiting the camera's ability to perform auto-exposure. I believe all current-generation cameras have a "stop the lens down and ...

Yes, using a 90EX as a master unit to trigger the 430EX II is exactly a use case that it was designed for. Keep in mind that this is an optical connection and it's not all that reliable or far reaching. For much more detail and additional non-optical options take a look at this previous question: How can I fire a single canon 430ex flash remotely from a ...

I don't know about the focus-by-wire bit, but this photo.net discussion thread includes side-by-side images of the mounts of a 5D and an EF-M, and shows that the EF-M did indeed have all the electrical contacts of the EOS mount. My guess would be that manually focusing with focus-by-wire will probably still work, since that's more about electronic ...

None of the Canon flashes can be used simultaneously as slave and master. The 550EX can only be used as a master on-camera (or connected by a TTL cable to a hotshoe), or a slave off-camera. It cannot be an off-camera slave and an off-camera master at the same time. The same is also true of the 580EX, 580EXII, and 600EX-RT. In addition, once the PC port on ...
