Hello out there in Pentax-Land. Does anyone have any experience with both of the following lens designs, and (if so) could compare them -
The Pentax FA / Tamron 28-200/3.8-5.6 (I understand that these are the same lens) - versus - The Sigma 28-200/3.5-5.6 Yes, I understand that these "do-everything" (<g>) lenses are chock-full of compromises, but nonetheless I am interested in their comparative optical and build qualities. Thanks. Fred
