Excerpt: I ordered this as a (much)smaller, lighter, cheaper alternative to a 24-70 f/2.8II. Trust me, it's as sharp as the f/2.8 zoom, plus it's a full-stop faster and it has IS! Honestly, I've read several reviews claiming that this should have been an L lens, and they're right, the build/image quality is that good. And the 24-70 has such a short range anyway, it's not that much of a compromise to take 1-2 steps forward or backward.
Summary: This is s a super fast lens with nice, sharp images. The bokeh is also nice for a moderately-priced lens. My favorite use is for video though. It has IS so you actually get nice, steady shots without a Glidecam or tripod. It's great for low-light indoor video. I'm very pleased with it so far! (I shoot with a Canon 5d Mark III - my other lenses are 24-70 f/2.8 L, 70-200 f/2.8 L IS II, 50mm 1.4, 100mm f/2.8 L Macro).
Summary: Just got this yesterday and already snapped about 200 test photos with it, including people, pets, and static objects around the home. I wanted to give it a good rundown. I have it installed on the Canon 70D and had to update my micro adjustment to +9, but every pic after that adjustment is exactly what I was hoping for. Will be great for indoor family gathering shots and dinner parties.
Summary: When i first ordered this lens I was afraid that I may need a wider lens to shoot at an important party indoors and for some group shots, but it ended up being the perfect lens for my 70d camera. The pictures came out crisp and clear, sharp, with brilliant and vivid colors. When they asked me to see some pictures, their jaws just about dropped. The lens didn't even need a micro focus adjustment.
Summary: The size and weight is the main reason that I choose canon over sigma. I am using it for street photography and having it on a canon 6D makes it easier than the heavier sigma. Overall, the image quality is sharp and the IS really helps in low light too.
Top optics, fast aperture, very good image stabalization.

Summary: The 35 F2 IS is essentially L-quality optics without the red-ring and it's associated weather sealing. That's the bottom line. If you want slightly sharper, go with Sigma 35mm F1.4 at twice the price. If you need wider aperture, then you must look elsewhere. If you find F2 to be enough for your purposes, or if you ever stop down from that, then the 35 F2 IS is great.
Excerpt: This makes a great fast standard lens for my 7D and a great 35mm lens on full frame. It is sharp at f2, which puts it at an advantage on a crop body over using a fast 50 on a full frame camera, as fast 50's they are often not very good at f2.
