Please note that we are still testing this feature and it might have small hick-ups. You can go with your mouse over picture taken with Canon to see Tokina crop at same aperture (f4.0) in small square. Stopping down improves the quality at 10mm but at 22mm the border quality improves from f/5.6 to f/8.On the other hand, barrel distortion on a wide end is slightly noticeable with Tokina, but the real minus are chromatic aberrations for both lenses.Ĭomparison of sharpness: Canon 10-22mm at f/4 vs Tokina 11-16mm at f/4.0 – mouse over to compare Border sharpness on Canon 10-22 is generally good except at 22mm where they’re a little soft at wide-open aperture. Beside the benefit of f2.8, better sharpness is one of the main characteristics of the 11-16mm.
When it comes to sharpness, Tokina beats the Canon in center and corners of the image.

Also you won’t be able to use full-time manual focusing like on Canon. This is something that we find not so practical at first and it takes time to get used to. On most lenses you have a switch but here you have to push-pull the focus ring in order to change from AF to MF. Switching between manual focus and auto focus is rather specific. Focus is precise but if you try and focus on the object several times, it tends to back focus sometimes so keep an eye on that just in case. Tokina focusing speed is satisfying some noise is noticeable but not obtrusive. Smaller zoom range, but great maximum aperture at f/2.8. Smaller zoom range lenses could and should produce more quality pictures compared to bigger zoom ranges. It is well known that primes are better choice for constant focal range. It is well build with its outer shell made of quality polycarbonate, and the zoom mechanism made of metal. Its field of view equals to 18-26mm on a full format camera.

This advantage in speed didn’t come for free as it due to that lacks some zoom range. It has a slightly narrower field of view but it is almost one full stop faster than Canon. Its build quality feels solid and firm, and it has a fast and silent USM motor with a full-time manual focusing as well. Its zoom range is equivalent to a 16-35mm on a full frame body. There is not much left to say about the Canon EF-S 10-22mm. On a Canon body the first choice would be of course the Canons EF-S 10-22mm f3.5–4.5 USM, but what about the less expensive Tokina 11-16mm f2.8? If you have an APS-C camera body – meaning 1.6x crop and want to go as wide as possible, there only few options available.
