SIGMA fp: The world's smallest and lightest full-frame mirrorless digital camera
The SIGMA fp measures just 11.26 x 6.99 x 4.53 cm and weighs a mere 370 g without a battery or memory card. The SIGMA Corporation has integrated a 35 mm 24.6 MP full-frame sensor, although it is a BSI CMOS sensor with a Bayer filter rather than a more specialist SIGMA Foveon sensor. The latter can capture red, green and blue pixels on three stacked, partially transparent layers, while the former is something that the majority of OEMs use.
The CMOS sensor has a light sensitivity of ISO 100 - 25,600 and can capture pictures as 14-bit DNG RAW. The SIGMA fp can also shoot at up to 18 FPS, but it can only buffer up to 12 photos, meaning that you must take a break after less than a second.
The SIGMA Corporation has designed the fp for flexibility, allowing it to be customised with interchangeable lenses and accessories. The company claims that the camera is compatible with over 50 lenses when using the Leica L-Mount, a standard that Leica, Panasonic and SIGMA launched as an Alliance in 2018. The SIGMA Corporation has gone into detail about the fp, which you can find here. It has not currently divulged pricing, but it does suggest contacting local SIGMA suppliers for more information.
