David, I too, use the Nikkor 16-85, but on a D5200. Please see attached sample image. I love the lens, and am trying to decide if I should upgrade to the D7100, mainly for the lack of AA filter and resultant sharpness increase. That, combined with all the other features like AF Fine Adjustment, Commander mode, weather-sealing, etc., make me think it's worth the $400 difference in price. If I'm wrong, any comments would be appreciated! Thanks, Steve
