Hi everybody ... I have decided to join the forum as I really want to learn about photography. At the outset, I am a helicopter pilot in the army and I happen to have the luck to get my hands on a Mamiya 645 DF with 4 lenses; a 55-110 mm, 35 mm, 150 mm and 210 mm with it. It belongs to my Squadron but as there aren't anybody well versed with photography it is lying pretty much unused. So if anybody wants to guide me from the word 'Go', it would be great.
