I am new to medium format photography and am looking for advice on getting a good medium format camera case for use in the field. I normally use Lowepro bags for my 35mm camera outfit and am partial to Lowepro. However, I have been reading some good reviews on Kata and Tamrac. I am open to any suggestions. Here is what I need to fit into my medium format bag: Fuji GSW690III, Mamiya 6 with 50mm, 75mm, 150mm lenses, Sekonic meter, Lee filters & filter holder, and, of course, plenty of film. Advice will be appreciated!
