This site is intended to collect the scattered knowledge that usually lives in forum threads, old reviews, YouTube comments, social media groups, and private testing notes: which lenses cover, which adapters work, which cameras are worth using, and what the format actually looks like in motion.
The emphasis is video and cinema use. Photography is welcome when it helps answer format, lens, coverage, or camera questions, but the centre of gravity is moving-image work.
A History Lesson: To understand the 1-inch format better read our article on the history of the 1-inch format.
While full-frame has become all the rage, the 1-inch format and its specific look remains useful and valuable. People may be drawn to the one inch format because it offers a smaller, lighter, less expensive, and more practical alternative to full frame, while still being capable of serious cinematic images. Its look is often closer to Super 16 than to modern full frame, with more depth of field, less exaggerated background blur, a more immediate documentary feeling, and a stronger sense of the subject existing inside its environment rather than being visually isolated from it. The smaller format can also make handheld work, long zoom ranges, compact lenses, and easier stabilization more practical. The tradeoff is that it usually cannot match full frame for low light performance, dynamic range, very shallow depth of field, or the breadth of available professional lens options.
