A question for the experianced hands out there. I want to get started in panoramic format and currently have an Omega View. What are the drawbacks (if any) to just cropping the 4X5 sheet rather than getting a 6X12 roll film back. I want to photograph a variety of subjects, arch,lands,travel. I realize I will probably be purchasing additional equip. in the future (linhoff,fuji617,too dear for my budget). Any ideas,comments ?
