I'm planning on getting the tokina 10-17, and i'm having a difficulty which dome port i should get.
I'm using a T3i in an ikelite housing and as far as i've seen there are 3 dome port options:
8" ikelite modular dome port
6" ikelite standard dome port
5" precision minidome.
read few threads and still havent made up my mind: is the 5"'s corner sharpness better? will the 6" have good results aswell? which should i get?
