C Hing們~ 除左Canon 原廠15mm，Sigma 8mm，15mm外，好似Tokina 10-17mm都可以用？但有黑角嗎？有C hing用FF機用呢支lens既相嗎？

有無C hing用Tokina落FF度？？

I did not use fisheye, as it has a lot of distortions, not as useful.

I am using Sigma 12-24 on my 5D Mark II, as it is the widest possible lens for FF. If you use it carefully, there is very little distortion, but having a view that no other lens can collect and compare. But watch out for it is soft at the edge, so beter using it at f /8 or smaller.

I have used Tokina 10-17 on D3. Image circle is gone after ~14-5mm.

I have tried my 10-17 on a full frame camera.....
10-17 is designed for aps-c
since it is designed for both nikon and canon aps-c which means 1.5x and 1.6x
therefore at 15mm onward, the image circle covers the FF image circle already.

Upon trial on 5D, even the focal length between 14 and 15 can cover FF.
Close to 14mm there will be very very little 黑角 especially small aperture.

<<It has a lot of distortion>> true, this is why it is designed for.
If you make use of those distortion, you will find it fun.
