Sigma's ultra-compact full-frame mirrorless with L-Mount, the smallest FF body available.
The Sigma fp launched in 2019 as the world's smallest and lightest full-frame mirrorless camera. With a pocketable body, L-Mount compatibility, and Cinema DNG RAW video recording, it targeted creative professionals who needed a compact full-frame tool for both stills and cinema work.
Key features include the 24.6MP BSI-CMOS sensor, Cinema DNG 4K RAW internal recording, CinemagDNG 12-bit output, L-Mount compatibility, weather-sealed die-cast aluminium body, and USB-C connectivity. There is no EVF — all composition is via the rear 3.15-inch screen.
The fp is unique in the market as the only truly pocket-sized full-frame interchangeable-lens camera. It uses the L-Mount and is compatible with Sigma, Panasonic, and Leica L-Mount lenses. The fp L later added a 61MP sensor.
Niche used market. Check the rear screen, weather seals, and Cinema DNG recording. The lack of EVF and IBIS makes this a specialist tool. For general photography the Panasonic S5 II is more practical. The fp excels for cinema work and creative applications.
