Beautiful 4K imaging
High-resolution quality of 4K movies17
Full-pixel readout with no pixel binning makes it possible to condense approximately 2.4 times18 the amount of data required for 4K (the equivalent of the amount of data required for 6K) into 3840 x 2160 4K output. This oversampling process plus full-frame pixel readout without binning results in the highest possible 4K movie image quality.
Efficient workflow and professional reliability
In addition to a magnesium alloy body that assures the camera’s all-around toughness and reliability, largely amplified versatile features enhance operability, supporting severe usage in professional photography.
Quad-VGA OLED Tru-Finder™
The new high-resolution 3686k-dot electronic viewfinder (EVF) shows a clear image with fine detail. The legendary ZEISS® T* Coating greatly reduces reflections. Smooth EVF images captured at a 120fps19 frame rate even allow you to easily track a subject in fast motion. Fluorine coating on the outer lens provides improved protection from dirt.
5-axis image stabilisation
New body-integrated, five-axis image stabilisation unit offers a 5.0-stop20 shutter speed advantage. The live-view monitor image is also stabilised, so you can compose images easily even when shooting a fast-moving subject. (1) Yaw (2) Pitch (3) Roll

FTP file transfer
A new terminal for wired LAN connection lets you transfer still images to an FTP server for viewing and management. Since FTPS (File Transfer Protocol over SSL/TLS) is supported, image files can be encrypted while being transferred.
My Menu and new menu interface
A new My Menu feature lets you register up to 30 menu items for instant recall, arrange items in any order and delete unused items. Also, primary menus have been reorganised for smoother search and operation.
Sony FE 24-105mm f/4 G OSS Lens
A compact, lightweight and comprehensive zoom
From 24 mm to 105 mm and F4 aperture throughout the zoom, the high-performance G Lens offers consistently high image quality. In addition to outstanding optical performance, it has a compact, lightweight design for portability and mobility befitting the E-mount system. Fast, precise AF and high reliability add to the broad utility of this fine zoom lens.
Excellent corner-to-corner imaging throughout the zoom range
Advanced optics achieve consistently high corner-to-corner resolution throughout the zoom range. Four aspherical elements effectively reduce aberration, while ED (Extra-low Dispersion) glass elements minimise chromatic aberration. A circular aperture and carefully controlled spherical aberration shape add expressive potential with beautiful, smooth background bokeh and natural highlights that complement outstanding in-focus sharpness and clarity.
A one-lens solution for mobile, versatile shooting
Excellent optical performance and a high zoom ratio are packed into a compact, lightweight design weighing only 663 grams (23.4 oz). The design extends to E-mount bodies for outstanding system mobility and handling ease. This one high-performance lens lets you shoot a wide range of subjects and situations. A minimum focus distance of 0.38 metres (1.25 ft) and built-in optical image stabilisation further enhance all-around versatility.
Constant F4 and fast, precise, quiet AF for stills and movies
A bright constant F4 maximum aperture throughout the zoom range keeps the brightness even when focal length is changed. Sony’s Direct Drive SSM (DDSSM) AF drive system offers fast, precise, quiet focusing. And a precision optical design minimises focus breathing. All of this makes the FE 24-105mm F4 G OSS an excellent choice for both stills and movies.
Professional reliability and operability
A fluorine coating on the front element prevents contaminants such as oils, grime and water from sticking to the front of the lens and makes them easier to remove if they do become attached to the lens surface. A dust and moisture resistant design1 and customisable focus hold button further contribute to professional operability and reliability.
