that's odd. doesn't the FA version have a focus limiter? I know that the DFA doesn't have one.
It does but it hunts a lot even with it turned on

I use the DFA 100 for just about anything, love the focal length, love the size of it and the results I get.
I dont know if these shots are any help, but they were shot with the DFA 100 on a *ist DS....no pp, cropping or straightening.... just converted & posted.

While the cars weren't at top speed, you can see by the "attitude" on the cars that they weren't exactly standing still either.
Cheers

Marc: Good point—MF is something I have used at outdoor concerts when the act doesn't move around too much. But when say a vocalist is pacing around the stage, manual focus can be really tough to pull off.
Yeah, that's the one situation it lets me down. But again, given the low light and stage clutter typical of many concerts,I suspect AF would struggle too.

As for the 100mm focal length, you're right, I think that it would be perfect for concerts--especially big, outdoor stages.
We all have different ways of seeing things, but for big outdoor stages, I'd want something much longer - in the 135-200 range. But for outdoors use, it doesn't normally have to be fast, so the DA50-200 works well enough for me. The M100/2.8 is more of a nightclub lens for me. But then, I'm wanting basically upper-body-and-instrument or head-shoulders-and-microphone, mostly.

I recently just went out to try to take photos of my friends on the track with the FA 100mm macro (I don't think it should be too different from the D-FA), and it was pretty bad. Just when the AF gets the target in focus, it gets out of focus again and back in focus, etc. About 1/2 of my shots were in focus that way. The 50-135mm SDM should perform much better though, as the 100mm macro wasn't desinged for fast action.
Did you have the AF mode set in AF-C (continuous)? That, along with panning, should help.

I was looking straight at him with AF-C. The macro lenses weren't designed to have accurate AF anyways, although it is pretty fast for stills. The main thing that puts me down is how much it hunts.
