Hi dear PDMLers, My apologies in advance if this topic has been discussed at length already, however I couldn't find it in my PDML archives.
Like many people around, I've always found that the *ist DS focuses quite slowly in poor lighting conditions. But last week-end, I took my MZ-5n out of its disgrace, and put on my F-50 f/1.7. I didn't have this lens yet when I bought the *ist DS, and had never used it before with the MZ. I must say I was immediately impressed by the AF speed! In both low light and normal light conditions, the MZ focuses way faster than the *ist. It's not just noticeable, it's like twice as fast!!! I wish I had such raw speed on my *ist! I used NiMH AA cells on both the MZ and the *ist DS. I assumed maybe the *ist DS draws more power for electronics, so I tried lithium batteries: it's a bit faster, but still not on par with the MZ still equipped with its NiMH cells. Is the *ist DS supposed to be so slow, or is my unit somehow bogus and I've failed to notice so far? Do any of you have an experience to share in this regard? My unit is still under guarantee for a few months, so I'd rather have it fixed now if it's abnormal...
