I'm shooting a documentary/instructional video on a shoestring budget and will use the GH1 and a GoPro Hero for my video. Audio will of course be handled off camera. I think I will need several lenses to cover all of my shooting. I will need an "interview" lens for 60 Minutes style interviews capable of shallow DOF and a focal length complimentary to the subject. I also will need a macro lens to shoot closeup, tripod shots of small digital displays in a vehicle. I also need a general use lens, for lack of a better term, for scenic shots and such. Panasonic lenses are very expensive so I've been looking at older canon FD lenses. I like the FD 35-105 macro lens. Can a macro lens be used as a normal lens for interviews? Since they're so cheap, I also plan on picking up a 50mm f1.4. Also, to use canon lenses on a GH1 I need an adapter. I know you have to double the focal length to get the 35mm equivalent when using a 4/3s camera, does the adapter make the correction more than double? What does it equate to? Any other ideas for good lenses to use on a tight budget?
