I used some manual lenses before, the only thing i hate about these are that when you put a small aperture your vieuwfinder turns blackNancyP wrote:
Manual focus - but there is a lot of depth of field at 8 mm! Unless you are shooting stock, you don't need to get L glass. Other options are the Sigma 4.5 mm (circle on APS-C) and 10 mm (covers all of APS-C territory) fisheyes. There are also some ultra-wide rectilinear lenses out there, but I assume that you are specifically wanting the fisheye distortion.
The sigma 4,5 will be to extream, i do not want to have black borders in my immage, that's a waist of pixles
So, I think i will go for a 10mm then
thanks for the information
