I'm making the switch to a GH2 (when they start shipping) from a D3000. Primarily I'm making the switch so I can do video. The more I read, the more excited I am about 4/3's and the GH2, especially the easy adaptability of old lenses. Since I'm new to 4/3 and video on anything with lenses, I'm not sure where to start. I'm going to pickup with GH2 w/ the 14-42mm lens, and at some point in the future the Panny 20mm. The rest of my lenses for now I'd like to be old MF lenses. I know it will likely take a lot of getting used to MF, and that's why I'd like some recommendations on lenses to start with. Should I stick with one brand? Minolta or Pentax for example? Seems that having one converter would be cheaper. What focal lengths would be good to start with to help me experiment as I continue to learn more? (I thought a ~28, ~50, and a ~85/100) I welcome any helpful advice, even if it's anti-adapting.
