I want to purchase a fisheye for 7D but am not sure what to get. I have looked into the canon 15mm 2.8 , sigma 10mm 2.8 and the tokina 10-17 3.5-4.5. Please give your thoughts on the pros and cons of each lens. I will mostly be shooting video with this lens and want to use it for some cool looking shots.
Also, is there an expanded focus button on the 7d that I can use with the primes to check focus?
thanks.
