Sigma 50 f1.4 soft?
I bought the sigma 50 1.4 a few weeks ago and I have noticed I don't get any sharp pictures till f2.0? Is that normal or did I just get a bad copy? I also noticed that it was front focusing a bit. Do I have to send it in K-5iis only can adjust to +and - 10.
Any thoughts, can anyone help?
