The Zacuto Kameleon Pro EVF is an electronic viewfinder that is compatible with DSLRs, mirrorless, and cine-style cameras. 

Co-designed with JTZ, this 1920 x 1080 resolution EVF supports up to DCI 4K input via HDMI and up to 1080p60 via SDI. The Kameleon Pro EVF features a 10,000:1 contrast ratio, 3D LUT support, joystick control, 4-pin LEMO power input, and four user-assignable buttons. Use the built-in S-Log2, S-Log3, C-Log, and V-Log presets, or import your preferred 3D LUT via the USB Type-C input port. Imaging tools include histogram, red peaking, three levels of edge enhancement peaking, facolourolor, anamorphic de-squeezing, and SMcolourolor bars. An auto-closing rubber eyecup helps prevent burn-in, and Zacuto's patented anti-fog technology keeps your view clear in humid or cold environments. The Kameleon Pro EVF's built-in -1 to +4 diopter enables you to get a comfortable view without your eyeglasses, and for greater vision correction, four stronger diopters are available separately.
