I'm probably not typical among photographers, but I find the extremely shallow depth of field created by the F1.2 aperture kind of disturbing. When working with people, I love blurring the background with my prime lenses, but I don't normally go any wider than 2.0
Thanks for the nice review. My favorite shot was the one of the chicken. The depth of field was just right for me.
I actually did a shoot for a woman who had pet chickens like that a few weeks ago. We were in a small back yard and I used my Sigma 50mm 1.4 wide open a lot to really blur the background. Must be something about chickens that needs a wide aperture. LOL!
I'm enjoying my prime lenses a lot more now that I have a 5D Mark III that will focus them accurately. Looking forward to using them more, but it is hard to give up the zoom.
