Sigma FP2 Review: Compact Full-Frame Hybrid Camera Tested at $2,199

PetaPixel's review of the $2,199 Sigma FP2 finds the compact full-frame camera delivers excellent image quality and autofocus despite a brick-like body and awkward add-on accessories. The 470-gram body carries a partially-stacked 24-megapixel sensor that reduces rolling-shutter artifacts, compensating for the absence of a mechanical shutter. A new battery, described as essentially identical to the Panasonic BLK22, lifts CIPA-rated endurance to 370 shots. The 2.1-million-dot rear LCD now articulates vertically for waist-level and overhead framing, and 1/4-20 threads across the chassis support cages, gimbals and accessories. Autofocus tracking, said to improve on the Sigma BF, handles eyes and inanimate objects reliably; burst shooting reaches 20 frames per second with a buffer of roughly 180 RAW frames. Video specs include 4Kp60, 120p with a crop, 6K open-gate up to 30p, H.264/H.265 and ProRes RAW HQ to external SSDs, plus waveforms and shutter-angle tools. Overheating limits 4Kp60 recording to 33 minutes, while 6K open-gate ran 90 minutes. The reviewer faults the side-mounted 5.76-million-dot EVF-21, the missing headphone jack, the lack of IBIS and the cost of attachments, and names the Panasonic S1 II and Panasonic S9 as alternatives.
