Originally posted by VaughnA Good answers all. A lot to think about. I've been considering the 16-45 and I might go that route to start on getting something wide with better quality than my kit 18-55WR. I'm also going to keep an eye out for one of the F28's. I think I'll stick to the AF lenses.
I think you made the right decision. I probably AF 90% of the time, and MF when necessary in problem situations, like night exposures. at 61 i can still MF in a pinch, but think of AF as more reliable and faster where the situation is right for it.
If you look at Pentax F 28 f2.8 lens in the database, the folks rave about them. Bought one and am very happy with it. Pretty small lens and it snaps to focus quickly. The downside is when i bought 2 months ago, there were 3 of them on ebay, and they all went for about $250. You might also look at that lineup of fast sigma's in this range. i think they made a 24, 28, and 30, seem to get good reports, heavier but faster. I didn't look in them in any detail because i wanted a smaller size.
