Great action shots pb.
Concerning the 50 F2, I've got the M model and it is a nice lens, but I also picked up a Ricoh 50 F1.7 after re-reading a Popular Photography test done years ago and it beats it by a little in resolution. Still have to figure out which has the best bokeh tho.
I've always loved the clack of the K1K shutter. Just appeals to me more then other cameras.
Here's a shot on the 4th with a 135mm F3.5 at F4 on Ektar. Held the shutter open on B and used the lens cap as a shutter to record multiple fireworks.
