I have a crop sensor camera, would this be ideal for a general use lens? I'm worried that I'll have to stand far back when filming.

It depends if you have other lenses with different focal distances but on a crop sensor it will be about 56mm. I know someone with a 70D who only uses this lens and it works great for him.

No, this is designed for crop-sensor bodies. You can use it on full frame, but the wide angle will get heavy vignetting.

The crop factor for micro four thirds cameras (like your GH) is 2x. So the actual focal length will be 60mm which I would consider more for portraiture, not good for wide angle shots.

It's a beautiful lens and should work fine on your camera. Just remember the crop factor turns this into a 28-65mm.

I have a Canon EOS Rebel 550D so I have a very similar sized/cropped sensor (1.6). I haven't used this lens as I bought it for my father in-law on his 6D, but I do have a 28mm f1.8 and a 50mm f1.8. The 20mm lens on a cropped sensor will give you a field of view equivalent to a 32mm lens, which could be still a little wide for portraits, but OK for Landscapes. If it was my money and you wanted a good portrait lens I would get the 50mm, (50mm is not really a portrait lens but you get some nice shots with it) field of view equivalent of about 80mm (only $110) as it is soooo sharp and clear. Its amazing. The 28mm is good but I certainly don't use it as much, but does give an equivalent field of view of 44.8mm almost the "standard 50mm". Sorry I cant advise much about the 20mm, but I have a few lens I have used on my 550d so maybe the incite will help your decision making process. Oh and just for the record I use a 17-40mm F4 lens as my standard lens as it covers a lot of the usable focal range that a standard lens on a full frame sensor would cover, but it is not cheap :( you could also look at the Canon 28-135mm f3.5-5.6 used.

I almost decided in favor of Sigma, but then I realized that Sigma is made for a crop camera only. While I'm not looking to buy an FF one any time soon, when I do, it will be costly, so I wouldn't have the money to follow it up with expensive lenses, not to mention that a good prime is a good prime, which I expect to last me a long while... So that is becoming a big drawback for me...

Since this is an EF lens, it will work fine, but using it on a 'crop sensor' camera, (I am) will increase the effective focal length X1.6. I bought an 'aftermarket' teleconvertor with mine and I love the combo (200x1.4x1.6 at maximum and still tack sharp). This is an amazing lens. period. and it's heavy

This lens was used on 35mm camera a film camera before the era of digital and crop sensor. It would definitely work on full frame sensor. I would check with Canon retailer just to make sure.

No compromise. The actual lens performance will likely be just as stellar. What you will experience is what is called "crop factor" essentially meaning the images from the lens will look more telephoto at equivalent focal lengths, also there will be less apparent depth of field at equivalent apertures. This is due to sensor size and you will experience the same thing on all lenses mounted to a smaller sensor. This is not necessarily bad, it's usually more preference. The lens itself will perform well if you know what to expect. Read through this: http://digital-photography-school.com/full-frame-sensor-vs-crop-sensor-which-is-right-for-you/ No compromise.

Yes. Just make sure you have the one that says "for Canon". It will work on all the crop sensor cameras. It's a great lens, take your time getting used to it - don't expect to pull it out of the box and get great shots immediately. There is a learning curve.

Hi - Just double-checked a couple of OM lenses on my Sony a7r using this adapter. I want to make sure I'm completely understanding the question: if you're asking whether there will be any vignetting of the image, the answer is no (except to the extent that a specific lens shows some light falloff at the edges, but that's not an adapter issue, and you'd have the same phenomenon on an OM film body). If the question is whether or not the image will be cropped (using the term to refer to the so-called "crop factor" associated with smaller-than-24x36 sensors): again, the answer's no. OM lenses are full-frame lenses, the a7 is a full-frame body - so no cropping of the image. Hope that's helpful!

You will be able to fill all the frame on cropped sensor cameras with focal distances between 10-15mm. The lens has a "limit" switch to limit this range, so you won't need to worry about it on cropped sensor cameras. It will allow the zoom ring to rotate only between that limited range.

I wouldn't buy this for d7100. Focal length is not useful for a crop sensor on the wide end. It's pretty fat and heavy lens, I would look into 16-85mm

If you don't want to have both on the lens, then I would use just the full frame hood. There's no rule either way. I think the APS-C adapter looks a little flimsy on its own. The ability to reduce stray light and therefore flares will be diminished without the extension on crop sensors. But I doubt you'll see much of a difference.

Yes, but keep a couple of things in mind. First, when you are composing your shot, especially if it's a portrait or nature shot, allow a little room at the top and bottom of your viewfinder. That will give you the "crop" factor. Also remember that your focal length will be approximately 125 mm instead of 85.

No, it is a dt lens which means it is for crop sensors. The a7 is a full frame. On top of that the the a7 uses the e-mount and this is an a-mount meaning it would also require an adapter to work properly.

Yes, but this lens is designed for a full-frame sensor, so there my be some lens crop, making the lens closer to (about) 100mm?
