I picked up my TT350P on the weekend. I just tested the Auto zoom function with the DA 55-300 PLM and DA 18-135 on my K-3. The zoom motor whirred away when I zoomed in and out with the 18-135, but not with the PLM.
I also tested it with the DFA 100, to see whether it just doesn't respond to telephoto focal lengths, or whether it's to do with the KAF4 mount on the PLM. I set the zoom manually at 28mm, then switched to auto. The zoom motor whirred again. I fired some test shots with the 100 with the zoom set manually to a wide setting and then set to auto. I heard the zoom change when I switched to auto. With the test shots I didn't have enough distance to subject to see whether the spread of light differed, although I'd have to say there didn't appear to be any difference in the lighting between the manual zoom setting at 28 and the auto zoom. I'm sorry, but that's inconclusive.
The zoom function worked fine in manual zoom mode.

Good idea Nigel. I've got a Metz 58 AF-1 but unfortunately I can't help. The zoom function is broken. (The diffuser was broken off when I got it.) It won't even zoom manually. It's stuck on 18 :-(
