eh, i've had more than my share of ai-s lenses at this point, and while they're fantastic lenses, nik is finally starting to replace them with better lenses for about the same price. my new 85/1.8g and 35/1.4g outperform the older equivalents by leaps and bounds and are actually lighter. they do cost a bit more, but the convenience, performance, availability, etc. make them worth it. at this point i would happily buy a full-frame d40/60/3000.
