Finding my ideal 6×9 folder – Largest Negative in a Compact Travel Format – by Zheng Li
I have owned and used many different types of medium format cameras (TLR, SLR, folder, rigid body rangefinder), and I enjoy all of them for different reasons. But this article is specifically about medium format folders, which provide a large negative in a compact and travel friendly form factor. Sometimes they are not much bigger or heavier than a 35mm rangefinder, while producing almost six times the film area.
