Smartflex 8x10 is the world's largest SLR, built for portrait film
Smartflex’s 8x10 SLR bucks the compact-camera rush with a 12.3-pound body, a mirror-prism finder, and support for portrait film giants.
While most camera talk in 2026 has leaned toward smaller bodies and retro compacts, Smartflex went in the opposite direction and built something so large it almost feels like a challenge. The Smartflex 8x10 is being billed as the world’s largest SLR, and Reflx Lab says it is the first 8x10-format SLR built in more than a century. For portrait film photographers, that is not just a stunt. It is a very specific answer to a very specific way of working.
The Smartflex 810 is aimed at an untapped niche in 8x10 portrait photography, where the attraction is not portability but control, ritual, and the ability to work with the biggest lenses in the format. Unlike most large-format cameras, which depend on a ground glass viewing screen, Smartflex uses an internal mirror-and-prism system to deliver a true single-lens reflex experience. The camera comes with a waist-level finder by default, with an eye-level finder planned, so the workflow stays close to the old reflex tradition while avoiding some of the slow, upside-down composition that defines a conventional view camera.
The numbers make the scale clear. Digital Camera World put the Smartflex 8x10 at 12.3 pounds, or 5.6 kilograms, before a lens is attached. Smartflex’s own body page says the shell itself weighs just over 2 kilograms and is reinforced with carbon-fiber panels and lightweight 3D-printing materials. The company also says the camera can support lenses in the 8 to 10 kilogram range, and it can be paired with a specially designed 300mm f/2.8 lens or an extension board for 600mm work. The 10×10-inch curtain shutter tops out at 1/1000 second, with a T-setting for wet plate work.
Smartflex says the 8x10 has completed testing and is officially available, with 15 sets of components prepared in advance after lessons from its Kickstarter experience. Reflx Lab calls it the second 8x10 large-format SLR in history, after the Graflex 810 from 1901, a name that still carries weight among camera history obsessives. That is the real appeal of the Smartflex 8x10: it is absurdly oversized, mechanically serious, and built for photographers who still want composition to happen at the glass, only with a mirror, a prism, and a century of old-school ambition behind it.
