I just purchased a Fuji GA645Zi primarily to be used for landscape photography when we take a trip to Hawaii in December. I wanted a lightweight camera to take with me, However, I have since found a number of comments on various websites that Medium Format is less suited to landscapes due to its reduced depth of field. They all pretty much conclude that MF really shines for portraits. Is that a fair comment to make about MF cameras? If so would my Nikon F100 be better suited for landscapes when used with the appropriate lens? One of the reasons I bought the Fuji was to get greater detail in my landscape images. After all, Peter Lik uses a Medium Format for his landscapes. In the MF arena, would it make any difference if I were to get something like a Voigtlander 690 with its huge negatives?
