[QUOTE="aroy, post: 211826, member: 16090"] Please check the focusing accuracy of your lens. A lot of AF lenses do not focus spot on, they either focus ahead or behind where you want. The simplest method of testing is to. . On a table place a graduated scale at an angle (best is 45 degrees), so that the graduations are away from you at the top and towards you at the bottom . Mount the camera on a tripod. The camera should be horizontally leveled and lense centre should be at a mark near the centre of the scale - say 6" mark on a 12" scale. . Use the central focus point only and focus on the 6" mark at the widest aperture of the lense (that will give minimum DOF) . Now study the shot on a computer terminal and determine where the best focus was. It is now simple maths to calculate the focus deviation.
