I just put up a video review (done with one hand) of the Gh1 with the 20mm f1.7 Friction Follow Focus.
I was apprehensive about purchasing a friction follow focus but trusted Ikan products and they have a 15 day return policy. I specifically went with this follow focus because I find that I always wind up throwing on the pancake as my "go to" lens (especially in low light) and this FF is able to toggle so that it can get in close to camera where the 20mm focus ring is. It is definitely a little pricey (little cheaper at B and H) but very well built and worth it if you find that you use the pancake a lot or own G series and lighter focus ring lenses. It also worked well with some of my FD lenses.
Lemme know if you have any questions or thoughts.
