[QUOTE="Fat Fingers, post: 591774, member: 41715"] You missed the point ..at F5.6 photographing a ruler the markings ( 1 mm ) are so blurred as not to be clear whats in focus and whats just blurred . I usually do the FF stopped down a bit to improve the clarity of the image ...Some lenses are sharp enough wide open others not. The 18-140 has a problem with the plastic ring at the front of the zoom collar ...it breaks off ...so get the superglue ready both mine have done it and there have been questions about this on forums.
