Tokina 11-16 on a FF body?

Just saw an online portfolio where the photographer stated that he uses his 5d2 with the Tokina 11-16. From my understanding the 11-16 is a EF-S equivalent lens. How is this possible for him to use with the 5d2? Wouldn't he get mirror slap?

The 11-16 is designed for crop sensors, but has a different design than the EF-S lens.

Unlike the EF-S lenses, the rear element does not protrude into the mirror box so there is no danger of the mirror hitting it. The Canon EF-S lens has a special mount that will not fit on a full frame EF camera mount (like the 6D or 5D).

The 11-16 has the standard EF mount and will fit on any EOS camera. But of course, there will be severe vignetting on a full frame....

You can use the 11-16 @ 15-16 on FF.

You can use 11-16 on Crop camera

I own and use it on both camera's

Be aware of its flare characteristics.

Heya,

I have the Tokina and full frame. Works fine. Vignettes at everything other than 16mm basically though. So on full frame, it's a 16mm F2.8 lens. Still quite wonderful, fast, and sharp.

Third party lenses that are made for APS-C are really EF mount. Not EF-S. EF-S is Canon's. The optics sizes and distances are what's different on the APS-C designed 3rd party lenses and then put on an EF mount. They work on any EOS camera. They just might vignette.

Very best,

I'm just still trying to decide on a lens other than the 17-40. I'm getting the 17-40 but want another wide that has a bigger aperture. I had the Roki 14mm and may get it again for Milky Way stuff

The lens can be used as a15-22 f4 lens on a full frame with very little to no vignetting.

it doesn't make sense to buy the 17-40L, and then buy the 11-16mm to gain that one mm on the wide end and f2.8...for the price of those two you could just get a 16-35mm f2.8 instead...or if you want to save a little bit, then the tokina 16-28mm f2.8
