I got my Panasonic GF1 last night. I am really impressed by it's form and shape . I put the 20mm on it and took couple of test shots and that's when I realized that it's really slow in focusing with 20mm. I have a G1 that focuses much much faster than the GF1. I have used PTool to hack the G1's firmware as it was a Japanese version and had to convert the language to English. I do plan to hack the GF1 for better video capabilities but was curious to know if the focusing speed is really that slow on GF1?
