Since I discovered that focusing my Holga micro four thirds lens was pointless, I went for a walk with the Panasonic GF2 (still hasn't sold yet) and the Holga lens focused to infinity. Results were.... still unpredictable. As an old computer tech support guy I am used to do trouble shooting but I really can't find any rhyme or reason in how this lens works.
Anyway, I have fun using it. That's the best thing about this kind of lens: it takes away that feeling of "I have a really great camera so I need to take a great photo" and you can just concentrate on enjoying being out taking photos of whatever you want to take a photo of
