I don't have a DB yet, but if it's an issue, just put the camera in manual mode and feather the shutter. Also, why other with a DB at all? get a cheap DSLR with histograms and shoot film. That's what I'm doing now. from my scanner, I get insane resolutions.
Also, the 80mm is a great freaking lens, but if you are going to be doing landscapes, I would think you would want the 45mm (wideangle) and the 120mm (panos).
personally, I want the 35mm and the 120mm.
