Fantastic lens! A comparison to Canon's f1.2 L mk II and f1.8...
I've always been hesitant to try sigma lenses because I hear a lot of problems that people have with the focusing on them. I passed up on the widely regarded 50mm f1.4 and 30mm f1.4 even though they got stellar reviews for the most part. When Sigma came out with the 85mm f1.4 for less than half the price of Canon's 85mm f1.2 L II, I had to see if it would save me a bundle in my search for a great 85mm.I took some time to compare this one to the 85mm f1.8 and the 85mm f1.2 L II by renting all three before making any decisions, and I have to say that this lens really impresses!The Sigma lens is much lighter than the Canon f1.2 and therefore, much easier to handle. The first thing that comes to mind when putting the canon f1.2 on my camera is how awkward everything feels - it's weight and "top-heaviness" really throw the balance off (I'm using a 7D) and makes the whole set-up feel wrong. With the sigma, I don't get this feel.... it feels right. It feels like...

A Sigma that rivals the Canon 85 1.4!
I am a pro wedding photographer who shoots primarily with zooms. I use prime lenses more as specialty lenses when I want to narrow depth of field or in extreme darkness. I own the Canon 85 1.8, itself an excellent lens, and rented a Canon 85 1.2L, a fabled Canon staple. The Sigma is actually better than the 85 1.8 at large apertures and rivals the Canon 85L in almost all respects. Compared to the Canon 85L, the Sigma is slightly more compact and lightweight. It's build is similar to my Canon 35 1.4L. More importantly, the Sigma focuses faster on all of my cameras--5D, 5DII, and the 50D. The Canon L has the advantage of being weather sealed and accepted by Canon Professional Services for pros who are members. The Canon 85L is also unique in that it opens to 1.2 rather than just 1.4.The Sigma autofocuses faster than the Canon L and almost as fast as the Canon 85 1.8. There have been reports of this lens hunting, having seizures, and making squeaking noises. If your copy of...

Autofocus DOES Work on Live View (Nikon D7000)
Some of you might have read my reviews on and , both complain about autofocus on live view, on Nikon D7000.This one, however, is a different story. Autofocus works perfectly. Fast and quiet, better than my old Nikkor 85mm f/1.4D.I'm not sure why it's different from those other fast primes from Sigma, probably because this lens is really new, so they got the reverse-engineering perfected.Build quality is top notch, smooth metal finish (not the rubbery/glittery finish). AF and MF switch, with MF overrides AF during AF.
