Popped up some pics. Didn't like the green/red lights, so I converted most of the pics to quadtones.

Still puzzles me. Why would the AF on the 85mm be slower than the 77mm? I'll have to continue the experiment.

Hi all,
Has anyone done a head to head comparision for autofocus with the FA*85 and the 77mm LTD on an *istDS in low light?
Took the 85mm out tonight for some shots. Took shots at the same venue a month ago, using the 77mm. I used the manual AF point select both times. Most of my shots are in portrait mode, so I set the AF to the topmost point (i.e. the leftmost "ear" if the camera was in landscape). Lighting was about the same both times, i.e. really dark (I'm shooting about 1/60 or 1/90 at ISO3200, wide open).
The 77mm had no problem snapping in focus. The FA*85 (which is a bit faster) seemed to hunt A LOT more, and often didn't find the focus at all, although it was fine when it did. But I missed a lot of shots because of it. Just realised I miss the switchable single/continuous AF of the PZ1. Hmm.
I'll post some pics later next week when I get a chance.
