Just interested as I would like to try and make a bikey video at some point, and I was wondering how well it would work with the 20mm lens as the autofocus seems to be a bit jumpy in video mode.
Grum – make sure you keep checking for firmware updates. The most recent one improved the autofucsing during video mode.
As for the debate about the GF1 being a DSLR replacement, I don't think that's where Panasonic have been pitching it, leaving that instead to the G1. It's been more that reviewers and users have found it has often replaced a DSLR for photo duties, me included.
Regarding value for money, then yes the GF1 is expensive, but then it is using new technology, which often results in a premium as the developers look to get back their investment. I don't think it's overpriced though.
Whilst I like my D90, what stops me buying a more expensive DSLR is the frustration that the more you spend, the bigger & heavier they become.
