I've been doing a ton of reading in books and on the internet about the d-7000.It seems to me that a lot of people dial in a lot of in camera sharpening when shooting jpeg.don't you loose a lot of data with lots of sharpening?I've been seeing sugestions of +7 to +9 levels.should'nt the d-7000 be able to produce tack sharp images with 0 sharpening with a lens known for producing tack sharp images providing all else is correct? thanks, Troy
