My large format camera is a 1950s linhof Color, a lightweight tan colored monorail not the Kardan Color, just the Colorolor. It is actually quite carry-able, especially when fitted with a short rail. When I was in my twenties I used to carry around in the back of my Mazda RX7 in its trunk case. This was in the 1980s.
In the 1990s, I bought a 120 roll film system camera, the Bronica SQ-AM, which allowed me to shoot 6 x 6 centimeter Square as well as 6 x 4.5. In 2007 I added an SQ-ai, and 3 lenses which I bought as a lot for $300! The 50 mm / 4 Pro Series lens was $1,900 in 1991, and the outfit came with the 50/4 PS, and an 80,and a 150, two backs, and two viewfinders, for the amazingly low price of $300!
There is no comparison in the handling speed and flexibility of a medium format camera compared to any sheet film camera using sheet film holders. My other larger format camera is a 1938 baby Speed Graphic, and the speed in operation is much slower than a crank-wind MF slr or TLR.
