So I've sold my DVX to start renting HD cams for projects but am also looking to buy an SLR just so I'll have something around to shoot video with for small shoots. I don't like the warping and rolling shutter of the D90 and I can't afford the Canon 5d so I'm closing in on the GH1, just wanted to make sure it's the best SLR out there in my price range for someone who wants to shoot a lot of video with it but would also enjoy having a great still camera around. How long can the GH1 continuously record? and what is the maximum size SD card I can get that will work with the camera? Thanks for any advice/tips this will bring!
