Hi, I recently bought a pentax kr but, unfortunately it had serious focusing issues, so had to return it. I have now bought a panasonic G2 and a 45-200mm lens, which has arrived today but my husband is bringing it home from work with him so I haven't got it yet. Ive always liked panasonic cameras, had an fz28/38 so I am hoping this will be good, any tips/advice welcome
