I'm currently on a 5D3 w/ 50mm 1.4, so the lens is my bottleneck at this point. I find myself often stepping farther back than i'd like to so I am thinking about purchasing a 35mm lens - i've used the 35L a lot before and just love it's performance but no so much it's price or weight. I am shooting landscape, portraits, doing some photojournalism (so 35mm is a lovely classic for me) and occasionally video.
I have read reviews saying the new 35mm f/2.0, while slower than the L, performs almost identical (except for center sharpness, build quality and color differences). Mainly, I am wondering how the autofocus on this thing is and how it may compare to a 50mm 1.4's pretty lackluster AF (though on the mark iii its superb) and if you guys think it would be worth the [Slight] upgrade. I lose a stop of light, but usually shoot at 2.0-2.8 anyway. Perhaps the IS will allow me to get a stop slower shutter speed to compensate?
Edit: also before anyone recommends the Sigma, id just prefer not to for now, thanks guys.
