I bought a used nikon d50 very cheap ( i know ) its been great but i took a shot of a light coloured subject f22 and upon upload to computer i notice lines running through the image.
i took a few white sheet photo tests and you can clearly see these lines at apetures f22, being a newbie dslr person i did not think to test to this level and the screens are not the best on these anyway .
