I bought a second hand 25mm/2.8 and noticed that when focused on short distance (eg. 30cm) the center is sharp but the corners are not sharp. When I turn the focusing ring to 25 cm without moving the camera (then, of course, the center is not sharp anymore) the corners become sharp !!!
Is this a peculiarity of the 25mm lens, or did I buy a broken lens???
