I really like it! The one I used belongs to a friend who assisted me for the shoot and came to the show with me (he's also a big fan). I have been eyeing the Canon EF 35mm f/1.4L II for a while, but this Sigma version is great and if I can find one in great condition priced lower than the Canon version, I might get that instead. I like it the same as my 85mm f/1.2. I don't think I could really compare the two though - it's not better or worse, just different. It is MUCH better than my Canon EF 35mm f/2 though.
