Stuck between a sigma 10mm 2.8 and the sigma 15mm 2.8... I have the 16-35 2.8L and I want something with more of a fisheye effect. I am leaning towards the 15mm right now, down the road it can be used on a FF, the 10mm cant. I also looked into the canon 10-22, but I just wasn't feeling the lens sample images (its also crop only). I know a few people rock canon 10-22's on here but anyone have thoughts on the sigma 15mm?
with the 5Dii @ 1799 right now, I might just bite the bullet and pick up a fisheye and the 5D.... I paid more for my 7D 2 or so years ago then what the 5D is @ right now. jeeesh.
