I've used the AF 50mm 1.8, 1.4, MF 1.2, MF 2.0 and the MF 45mm 2.8. Additionally, I've used the 55mm f/2.8 AIS and 35mm f/1.4 AIS. The best results with a D-200 were, for me, the two AF lenses and there was no detectable difference between the 1.4 and the 1.8. The 1.4 does need a lens hood where the 1.8 is recessed enough so that one is really not required. This makes the 1.8 an incredible value. I was really hoping that the 45mm would do better and it does with film. For some reason, this lens doesn't behave that well on my D-200 (better at close distances, but infinity is just soft). Interestingly, the 50mm 1.2 AIS and 35mm 1.4 AIS perform VERY well on the D-200. Maybe not quite as sharp at the edges as the two AF lenses, but certainly a better build quality and silky smooth manual focussing which I very much appreciate. I actually did test all of these lenses shortly after getting my D-200 and was somewhat surprised at how well the AF lenses did. As always, these were my personal results and your mileage may vary based on sample variation, etc.
