I have always been a fan of Fisheye and Ultrawide lenses, right back to my film days, the first Fisheye lens I owned was a Sigma 15mm, all manual, all metal beauty that I still own (although I don’t use it anymore, it’s just a paperweight). So with the move to digital this was an area of creativity that I was sorely missing. I purchased a wide angle zoom, 17-40mm for my full frame body which was great for landscapes but I needed wider, I needed Fisheye.
