On aps-c senors (my t3i), will this be a true 11-16 mm or will it be cropped?

Technically it's more like 17.6-25.6mm (remember to always multiply by 1.6 to get the true equivalence of the lens). That doesn't really matter even on your cropped sensor T3i, since this 11-16 is made specifically for a cropped sensor camera. If you were to put this lens on a non-cropped sensor camera (full-frame like the 5D) you would notice that you could actually see the corners of the lens vignetting pretty bad. It's truly intended to be used for cropped sensor and it's the right type of wide angle lens for most applications. It'll work perfectly for your camera.

It will be cropped. To equal as a full frame sensor, it will show 17.6-25.6mm (1.6x11=17.6; 1.6x16=25.6)

That's maybe a little more confusing and involved question than you know. I believe that TECHNICALLY one could say that an 11-16 is an 11-16 is an 11-16, no matter what camera it is on. However, that is not what you really want to know. You want to know how it ACTS on your camera. It acts like an 18-26 on your 1.6x camera. Know that lens makers never do any calculation for you - they put the 35mm or full-frame numbers. So any lens you see, you should multiply by 1.6 to see how that lens would act on your camera. Even if the lens is designed for crop sensor cameras like this one is, they never do the multiplication for you. For instance, the 18-55 that probably came with your camera really acts like a 29-88, so this lens is considerably wider than the kit lens. One last analogy: If you had this lens set to the widest on your camera, and your buddy had a 17-40 set to its widest on a full-frame camera, you would have approximately the same field of view.

The Tokina 11-16 is for cropped sensor cameras like the T3i; you'll see some vignetting if used on the a full frame camera

Only on full frame format it is true 11-16mm with vignettes on wider opening. On your camera it is like 17.6 to 25.6, but with no vignettes and very bright and nice (it is 2.8). Of course you know that your 18-55mm kit lens also is in fact like 28.8 to 88 mm. Hope it helps.

Cropped doesn't change what the lens captures, just what the sensor sees. If you want an approximation of the difference, buy or make a mat (the thing you'd use when putting a print into a picture frame). Make it about 2 inches on a side. Then put the mat over your monitor. See what's "cropped out" that'd the difference between full frame and cropped sensor. The visible stuff is exactly the same for both. It is just that a portion, about 40%, is not caught by the sensor.So, if you want technical, it is and always will be a 11-16 lens. If you want practical, you'll get the same on your 60D sensor that a 18-26 would get on a full frame body's sensor. Cropped doesn't change what the lens captures, just what the sensor sees.

Yes it will fit and works just fine. However, the camera will automatically adjust to APS-C size.

I never noticed any cropping. I think there would only be cropping if you got the wrong size for your camera i.e. magnifier is smaller than the lcd screen

The t3i has a Canon aps-c sized sensor, which carries a crop factor relative to full frame of 1.6. That means that this 35mm lens would have a field of view on your camera equivalent to a 56mm lens on full frame (35 x 1.6 = 56). With a goal of a 50mm field of view on aps-c, you would need a 31mm lens - this focal length isn't common, but Sigma has a decently rated 30/1.4 available, and canon offers a couple of lenses at the 28mm focal length (I know of a 1.8 and a 2.8IS cousin to this 35mm off the top of my head). There are other aspects of lens physics that keep the equivalence due to crop factors from being so cut and dried as 56mm on aps-c is equal to 35mm on FF, such as perspective compression and bokeh, but by strictly field of view this equivalence would hold.

On an APS-C NEX it will be 1.5 x focal length, so it'll be 28.5mm. I actually carry this one more often than my Sigma 30mm.

This is a 1.6x cropped lens that will only work on cameras with the smaller APS-C sensor. It will not work on 5DMk3, for example.

The focal length multiplier (crop factor) is 1.6x. It uses the same sensor as the EOS T4i.

I don't know but I suspect so. I use it on a 5n and there is some cropping.
2271202
Yes this will be right around normal on a crop sensor. On my full frame its a little bit wide, like a Leica field camera from the film days - gives a bit more background which is great for story telling.

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.

You can use it, but the focal length on the crop sensor will be equivalent to a 26-45mm lens.

Yes but it will be cropped. This lens is specifically designed for smaller sensors. Full frame lenses work with smaller sensors much better that this one will work for a full frame sensor.

The others have long since answered your question but I still don't get why the EOS 6D is full frame yet they made the 7D an APS-C 1.6x cropped sensor? Would be nice if Canon would use common sense in their model naming convention!
1658438
Yes I believe you will especially on the 11-16mm. But I also think that shooting with that wide of lens, in most cases you could afford to crop it out if necessary.
849429
Yes, the one I bought did not crop and didn't darken the corners as well. Mechanically it's ok too but we''ll see for how long.. One more thing: I assume these A7 cameras will work with R- lenses better than with M- lenses. Espexially the wide angles. My 35/1,4ASPH starts 'working' without heavy vigmetting and blurring in the corners only from f8 and further on!.

The exact ratio for the Sony APS-C is 1.56, so the result is closer to 760mm

Being a "DT" lens meaning the area of lens is designed for APSC, it can only be used in "crop" mode meaning the field of view will be APSC (~70%) of frame and the picture will be cropped to around 12 MP.
