I am working with a friend who recently bought a Nikon D5100. The kit lens and the AF Nikkor 50mm 1:1:8 D lens do not give a sharp result. I am attaching two comparison shots taken with the 50 mm lens on D50 and D5100 bodies. The D50 appears sharper. The downloaded files highlight the differences better than those in the post.
What do you think? Is this the best the D5100 can do or is something wrong with it? Are we missing something? What would you do?
Thanks for the help.
IMO the auto focus is being fooled by the mass of detail in all the depth levels of the subjects. Try on this type of subject to manually focus the lens. There should be NO difference in the exposures either. The lens has no bearing on the exposure. 1/250 at whatever aperture should be the same on all the pics of identical subject in the same ambient lighting conditions. Incorrect exposure will always decrease the sharpness of the image, but IMO under exposure allows you more latitude in Post Processing. If the image is overexposed you cannot put the detail back!
