With a compact design for solo shooters, travel applications, and to serve as an ideal B cam, the Sony FX3 borrows from both the Cinema Line and Alpha series of cameras to create an optimized portable cinema camera. The FX3 features all of the imaging attributes you'd expect from this class but sports a newly designed body that's hand-holdable, with a streamlined and minimal profile, and has a "cage-free" design, indicating the ability to secure various accessories directly to the camera body. Its 12.1MP Exmor R BSI CMOS sensor (10.2MP effective in video mode) pairs with a BIONZ XR processor to achieve UHD 4K video capture with internal 10-bit 4:2:2 sampling or 16-bit raw output. The sensor's BSI design heightens clarity and sensitivity, with an expandable ISO 80-409600 range and greater-than 15-stop dynamic range for working in mixed lighting conditions. Benefitting color and tonal control, an S-Cinetone mode can be used for matching to VENICE, FX9, or FX6 sources and there is also S-Log3/2 gamut support and 10-bit HLG for simple HDR productions. The sensor and processor also work together to greatly reduce rolling shutter and the sensor's design incorporates a Fast Hybrid AF system for intelligent and quick focusing performance and subject tracking. Beyond the physical design just being compact, it's also built to maximize efficiency and operability through the inclusion of an articulating 3.0" touchscreen LCD, a removable shoe-mounted top handle with dual XLR mic inputs, and 5-axis mechanical image stabilization for smoother handheld recording. The 28-70mm f/2.8 DG DN Contemporary Lens for Sony E-Mount from Sigma is a versatile wide-angle to portrait-length zoom characterized by its f/2.8 constant maximum aperture. The design suits working in available lighting conditions while affording increased control over depth of field. More lightweight and compact than similar 24-70mm lenses, it's optical design incorporates two FLD and two SLD low-dispersion elements plus three aspherical elements that reduce a variety of aberrations to achieve high sharpness, enhanced clarity, and improved color accuracy. It features just one lightweight focusing element, which keeps the AF unit small. This, along with a quiet and fast stepping motor, makes for responsive and near-silent autofocus performance, an ideal combination for filmmakers looking for a high-performance, lightweight, and easy-to-handle camera system that works well with a gimbal or other accessories. Each optical surface features Super Multi-Layer and Nano Porous coatings to improve contrast and color rendering by suppressing lens flare and ghosting for optimal light transmission, and an added water- and oil-repellent coating on the front optic helps keep the lens free from smudges and droplets. The weather-sealed design benefits working in trying environmental conditions, and a nine-blade rounded diaphragm contributes a pleasing bokeh quality when using wider apertures.
