I've been well-satisfied with the two Voigtlander folders I have. The build quality is very good, which is important for old folding cameras with so many moving parts.
The 6x9 Bessa with guess-focus was only like $70 a couple years back... with a Voigtar f/4.5 lens that needs to be stopped down to f/16 for landscape. 1/100 max shutter on mine so just barely hand-holdable.
The 6x9 Bessa RF was over $300, for a lens you can use at f/11 for landscape and a coupled, but dim, rangefinder, along with 1/400 speed.
They were made around 1938. Both of them can fit in my shorts pocket but the non-RF fits a little better. They also made some good 6x6 models. And yes, expect image quality to be a little lower than a good TLR even when stopped down. Even if you get one with a very good lens, the lens is likely not exactly in the right place. But good luck trying to fit a TLR in a shorts pocket. Folders are great cameras for hiking.
