Do you think it is the K-r's fault or lens fault? I take a lot of photos at 50mm f2.8, and this is a big disadvantage for me.
To be honest I havent had too much opportunity to test it outdoors in natural light. Most of my fooling around has been done in the evening inside with various types of lights.
I think it is more the lens than the camera but I only have a 90mm to compare it to. It could also be a factor of the mix of lighting, or even just my copy of the lens.
Ive only really noticed it when I was testing to try and find it. I dont think it will really be an issue for most shooting. And likely with decent natural lighting and some AF adjust it wont be an issue at all.
Its still razor sharp and a nice lens in any case especially for the cash.
