Most of my shooting is travel-based, and while the cameras I shoot have changed a little over the years, it's basically always this set up: a medium format camera (went from TLR to SLR now back to TLR - currently a Rolleiflex), and 35mm camera (almost always my Nikon FE with 2 or 3 lenses - 20 or 28mm, 50mm, and maybe 105mm), and a Holga, which is so light it barely registers. Occasionally I'll bring something extra, like a pinhole camera, but honestly, the more gear I have, the worse it is. Even if I bring all the cameras with me, I'll usually just use one main camera for shooting, but carry another as back-up, or for alternatives to the black and white film I have in my main shooter (the Rolleiflex). I often use the FE for colour or infrared work, or for other film speeds, if I know I'll be going between brightly-lit and dimly-lit areas in a short amount of time. Part of me has been thinking about just shooting with 2 TLRs so I can limit the amount of film I bring, but then I'm stuck with no wide angle, which can be a problem.
