i have been shooting since 1970. have d200, 2 d7000's. the d7000 with the 18-105, & 18-200 the worst. 90% of images not sharp. once in great while, when contrast permits the image is tack sharp. do not believe it is back focusing issue. they basically put these cameras out there w/inferior components obviously. they assume we will fix w/post production, which is limited at best unless you enjoy immense amounts of artifacting. unfortunate.
