Originally posted by Pål Jensen But DOF is rarely a problem for the 645 format
however, that is largely dependant on how large you are printing. DOF issues are magnified substantially by how large the image is printed, and with 40Mp you can produce some pretty large prints indeed; Can you say that everything from the moss on the rocks to the trees on the hills will be rendered crisply at 8x10,16X20,32X40 or 64X80?
I know large format photographers who are using full chip 645 digital backs that are focus stacking to increase DOF.
