50mm f/1.8 STM - mixed AF results

I received my 50mm f/1.8 STM today so tested it for AF performance, mainly because I never got the prior 50mm f/1.8 to AF well at all on my 650D (or XSi before that). This new lens is better, at least in "good room light" where I found that AF was quite good. It was less consistent in lower light Some were right on, some front focused, some rear focused. Disappointingly, Live View AF was about as inconsistent as normal AF in low light.

As an 80mm-equiv portrait lens in decent light, this lens works. In lower light, the AF isn't good enough to use. I'm undecided if I'm going to keep it. Hmm, maybe the really low light shots would be "social" shots with flash so a smaller lens opening would work. Don't know yet...
