I have a landscape that I would like to try at 16x20, but most of the portraits, even those with the Mamiya, I find are better at smaller sizes.
I have found that for my work, the rangefinders are great. I'm interested in keeping my back healthy, and not carrying around really heavy gear, and as someone mentioned, they are very fluid to work with. When I first started to shoot with the Mamiya, it just seemed so much easier than my big overcomplicated SLR, and that's why I also wanted the versatilty of a 35mm rangefinder to complement the Mamiya. None of these cameras are cheap (even used, frankly), which is the big bummer, since I'd still like at least one more lens for each. But having a couple of different formats is really the best way to have the tools for as many situations as possible.
Now if I decide to add large format to my 'tool kit' it'll be the lightest weight field camera I can find!!
