The Mamiya 7 is going to be my only camera* on a trip through Vietnam, Cambodia, and Laos. I’ve done this before and it is much nicer having 20 shots/roll with 220 than changing out every ten frames with 120 film (6x7 format). The only hitch is not wanting to waste film when I want to change between color and B&W. I decided to order three 5-packs of Portra 400 in 220 one 5-pack of TMX in 120. I’ll also bring a bunch of expired Konica 160P in 120.
*Really this time. Honest.
