    Hi. I've got a problem with my Minolta lens. There's something wrong with the right side of an image. It is a little bit blurry while the rest of it is quite ok. I don't know if it is lens problem or something is wrong with my camera (Sony SLT a37) Here example:[​IMG]

    Thanks for help;)

    Take a picture perpendicular to a flat subject (like the classic brick wall shot) ... then examine the image.

    Hang up a full page from the newpaper and setup your camera on a tripod with radio release if possible. Set up the camera perpendicular to the paper like dxqcanada wrote with the ISO set to the minimum using Aperture priority. Set the lens to 70mm and take shots of the paper at each f/stop ranging from the largest to the smallest in 1 stop increments. Do the same at 100mm, and 150mm and 210mm moving the camera rig back to compensate. Then examine the pictures at 1:1. This should really let you see what is happening with your lens. Post some of the results and let us see what is going on.
