I had this beauty with the X700 and XD. Liked it a lot then, but since the digital age I decided to make it work on the Minolta 7D. Chipped for Image Stability and everything: hacked into an AF mount.
So I also wanted to try this on the GF1. No pics of the combo yet, but I do have some of the result.
Outdoor festival, clear sky, I was getting cold. No IS on the GF1, but I can now state that IS is not necessary.

Ed Kowalczyk was doing the third concert with his new band and it was great!

No crops, no tricks.
