i know its for a cropped body, but can I still use it for a FF body?
[...] Digital single-lens reflex DX lens_ dedicated to digital SLR cameras with APS-C sized sensors.
*The lens is designed for Digital cameras with APS-C sized CMOS and CCD sensors (DX) , not designed for cameras with Full Frame sensors (FX).
Narutosan said:Thanks for the info, im asking this because a friend of mine is using Tokina11-16 but he can use it though vignetting will appear most likely below 15, so does it means I can use it also but should be above 16 to avoid vignetting right? Sorry for my question, not really familiar with these lenses, worrying that it might damage my FF camera if I put in my Tokina lens, just taking precautions.
Narutosan said:I really had no idea if EF or EF-S mount, Tokina website does not say anything about EF or EF-S, though it says it is not designed for FF.
Canon EF-S lenses are made so they CANNOT mechanically be fit onto an EF body. This isn't necessarily true with 3rd party lenses. I used to have a Sigma 17-70 that fit onto my old Canon d60 (crop body but with full-frame mirror, so EF-S lenses could not fit). Some photogs have successfully modded their EF-S lens to fit EF bodies.
You might want to try and judge the amount of vignetting yourself. But be careful about your mirror clearance i.e. if the lens rear element intrudes too far into the body, the mirror might hit it when it flips up.
FOrget about modding EF-S lenses to fit Non-crop bodies... I tried that with my 10-22 to fit my 1D3, yes I get 12mm wide angle but the lens simply does not have the resolving power for larger sensors. The result is even worse than 17-40L's corners.
Hi Narutosan, there's been a lot of misinformation and wild guesses being thrown about here.
The fact of the matter is, unlike Canon's EF-S mount... from my experience all the Sigma and Tokina lenses designed for crop can be used on FF or 1.3x crop. The only 2 issues you need to decide for yourself is, what is your personal tolerance for vignetting? That would determine the wide end of the zoom you intend to use. Secondly, some lenses do not have enough resolving power, but real world usage may be acceptable especially if you're posting to FB or Flickr.
not true. From your experience then, i wonder how many camera mirror have you broke?
Each 3rd party brand has their own code for lenes made for crop or FF. You can always use fullframe lenses on crop sensors camera but NOT the other way round. Will it fit or not is something else, should it fit, hitting the shutter button will have you make a trip to Canon.
Sigma
Fullframe - DG
Crop - DC
Tokina
Fullframe - DX, FX
These brand has their own code for other things but means the same thing such as OS for IS, HSM for Ultrasonic etc etc.
The Sigma 10-20 fits on the 5D, so I don't see why it wouldn't mount on the 5DmkII. Although it's classified as crop lens, the elements are NOT in the way of the mirror (as they would be with Canon EF-S lenses - the Canon 10-22, for example, cannot be mounted).
HOWEVER, it does vignette pretty severely below about 15mm or so.
