DJ-Optical, which sells its lenses on eBay, has a new ultra-slim manual-focus pancake lens that looks quite stylish.
Shown off earlier this year at the 2026 China P&E Imaging Show, per Leica Rumors, the new DJ-Optical Ultra Slim 35mm f/3.5 Pancake Lens is a manual focus prime for Leica M mount. It is just 15 millimeters (0.59 inches) long, not counting the mount itself.
The manual focus lens has eight elements arranged across five groups. That’s quite a bit of glass for such a thin lens. It includes one ED element and a trio of high-refractive index elements. The aperture ranges from f/3.5 to f/16, with eight aperture blades. Although it is rangefinder-coupled and focuses down to 0.7 meters, it can focus as close as 0.5 meters in live view. It can also be easily adapted to non-M cameras, though any adapter adds a bit of length to the pancake lens.
