Is this lens good for cannon 7D?

It has an EF-S mount, so it will not fit on Canon full frame cameras - only the APS-C cameras, like the Rebel.

Works perfectly for my EOS Rebel. Great value.Don't buy optional Lens Hood, it comes with one.

Yes it should work well with the canon 7D and any other canon EOS digital cameras.

You don't want this lens for the a7. It will attach and take photos in crop mode. But you would be much better off with a full frame lens (either native E mount, or another full frame lens with a compatible converter). If you had higher quality non-full-frame e-mount lenses, those might be worth using in crop mode, I suppose. But this lens has too many optical compromises.

I've used this lens on my original 40D and my current 7D. With Canon's pattern of making lenses and cameras that are consistently comparable I would be surprised if it didn't work.

Yep! I will work great with a 7D. Just remember the Canon 7D sensor has a crop-factor of 1.6, so this means this lens would act like a 160-640mm lens would on a full-framed camera.

As long as you buy the Sigma lens with a Canon mount, it should work fine. I use mine on a 7D.

Hi Ling, it is a very good choice if you are not looking for a Canon lens, I have a Canon 550D and it is working perfectly on it.

I use the 2X on a SP 70-300mm F/4-5.6 Di VC USD lens, on a T3i camera. It works nicely for me but don't know how it would work on a 7D. Sorry I can't be of more help.

yes, I tested and it was very sharp on 7R, AF worked really well also, this lens the only solution to WIDE ANGLE for Sony 7/7R

Yes, I use it for my t2iand 7D,and my 5d mark III. Any DSLR canon camera. Just remember your camera is APS-c not a full frame camera mean that the lens 24-105 is not 24 but times 1.6 and your 105mm is 1.6 X

I am using with a 7D with no problem. It is cheap enough to try even if you are not sure.

It works fine for 7d, but big and heavy. I prefer use single battery, light and can shot up to 700 shots with its original battery per charge.

Yes. It will work well on 7D. It will have a cropped factor on 7D or any similar sensor. Essentially, it will have zoomed-in effect compared to as if on 5DMKIII, 6D, or any other full frame bodies. But at 17mm, even on a cropped body, still provides a very wide view.

I believe so but keep in mind this lens is designed for APS-C 'cropped' sensors so you should set up your a7, which is a full frame camera, in cropped mode. It will produce lower megapixel images.

Yes, it will work on the Canon 30d. This lens is designed for the smaller APS size sensor. Accordingly, it will work on the Rebels, the X0D series and the 7D, but not on the 5D, 6D, or the 1D.

Unless you are shooting videos of close up images like insects, I wouldn't suggest this lens. That said, this is an excellent lens for what it was designed to do. I use it on a 70D.

Presumably it will. I bought the lens for my Canon 7D. But because of your question, just now I tried it out using my old 30D body. It works; but on a dark, overcast day (as it is here in CT today), the 30D has severe limitations compared to the 7D. With the 30D, I had to shoot at low speeds; but with the 7D, I'm sure I could get acceptable exposures shooting much faster.

I have used this lens sparingly on my Canon EOS 6D. I have not experienced your problem.
