I'm very interested in the 35mm/1.4, the 85mm/1.4 and the upcoming 24mm/1.4 for manual focus video stuff for my GH2. I'm testing out about 8 different Canon FD's at the moment, and have had my 50mm/1.4 for a long time. But, is one mount going to be better in the long haul? Nikon? I don't plan on buying any other type of auto lenses that aren't MFT, but just trying to think long term? Thoughts?
