Sigma has announced an innovative new competitor in the full-frame mirrorless category with its L-mount Sigma fp, the smallest and lightest full-frame interchangeable lens camera to date.
The Sigma fp (‘fortissimo pianissimo’) is equipped with a 24.6MP BSI-CMOS sensor with a ‘conventional’ Bayer colour filter rather than using Sigma’s Foveon sensor technology. The sensor can capture 14-bit DNG files
It takes the final step in the migration to a fully digital camera design – ditching a mechanical shutter and the associated moving parts entirely. As a consequence any shutter shock is eliminated and the camera can be operated silently and at shutter speeds ‘up to’ 18fps. And of course there is no shutter to wear out!
Dimensions are 113 x 70 x 45mm and it weighs 420 grams including battery.
The camera has a ‘native’ ISO range of 100-25,600, expandable from to 6-102,400. The AF system – which supports Eye AF, is contrast-detect, and Sigma claims it can focus down to -5EV.
It has extensive in-camera image manipulation controls including a tone curve adjustment function in addition and ‘Fill Light’. There are also ‘Tone’ and ‘Color’ buttons for quick access to tone control and color mode menus.
On release, the Sigma fp will be supported by a range of lenses, with Sigma itself offering 14 L-mount lenses. Panasonic and Leica L-mount lenses are also compatible, and using the Sigma MC-21 converter, Sigma SA mount and Sigma’s Canon EF mount lenses can also be used. Cine lenses are also compatible via a mount converter.
Shooting video, the Sigma fp supports 12-bit UHD 4K/24p DNG video and offers sophisticated video features such as a waveform monitor, shutter angle control and timecode. There’s also a ‘director mode’ for previewing video at other aspect ratios. To help control heat distribution, Sigma has built a heat sink into the new model.
The Auto HDR function takes advantage of the electronic shutter to take multiple pictures of different exposures (3 frames for still photography and 2 frames for video) at once, which can then be merged into a single picture or video with a much broader dynamic range that achievable in normal shooting.
The Cinemagraph function, meanwhile, achieves a hybrid between still photography and video in the form of animated GIFs in which parts of a still image keep moving. With this function, the SIGMA fp is capable of creating Cinemagraphs in-camera.
(The Auto HDR function in the Cine mode and the Cinemagraph function are to become available via firmware update scheduled at a later date.)
Release is scheduled for sometime this spring, with no pricing details surfacing as yet.
