I'm looking for a new digital back to use with a Linhof M679 large format camera, chiefly for architectural work. The P30 seems ideal, but Phase One's publicity states that wide angles or large format tilts and swings may cause colour casts. This warning isn't given for the P45.
Before I talk to the dealer I'd like to be better informed, does anyone know why the P30 gets a health warning but the P45 doesn't?
