High-quality video recording
Record video in stunning 4K quality at up to 60p, with full pixel readout and no pixel binning. Discerning filmmakers can use the α 7 IV to record content in 10-bit depth and 4:2:2 color sampling, and produce cinema-quality images via S-CINETONE/S-LOG 3 image profiles without much post-production effort.
The α 7 IV also offers unique video tools such as a Digital Focus Map and innovative Breathing Compensation, available only on Sony E-mount lenses. Thanks to the heat dissipation structure, video recording over a long period of time is no problem.
Shake-free images
The built-in 5-axis optical image stabilization (IBIS) ensures shake-free images. When shooting handheld video, the Active mode provides reliable support and compensates for camera shake. But shake can also be eliminated afterwards thanks to the recording of gyro and lens data.
Live streaming made easy

The SIGMA 28-70mm F2.8 DG DN | Contemporary redefines the standard zoom lens for mirrorless cameras:
It combines outstanding optical performance and a continuous aperture of F2.8 with a lightweight and compact body.
Design-wise, the 28-70mm F2.8 DG DN | Contemporary is based on the 24-70mm F2.8 DG DN | Art, but with a focal length range starting at 28mm. This makes the lens body significantly smaller and lighter, while maintaining the same outstanding optical performance.
The slightly smaller wide-angle range of the 28-70mm F2.8 DG DN | Contemporary compared to the 24-70mm F2.8 DG DN | Art has made it possible to significantly reduce the size of the 28-70mm body. The Contemporary concept balances performance and handiness.
The new Lens features a single, lightweight focusing element, so the AF unit can also be kept small. Together with a quiet and fast stepper motor, this ensures responsive and virtually silent autofocus performance.
The 28-70mm F2.8 DG DN | Contemporary weighs 470g on its own and just 890g when combined with the SIGMA fp, for example. At less than 1kg, such an outstandingly lightweight camera system gives photographers an enormous amount of freedom and flexibility to realize their creative visions. It is also a perfect choice for filmmakers looking for a powerful, lightweight and easy-to-handle camera system that also works well with a gimbal and other accessories.
Based on the design of the Art product line
The optical design of the SIGMA 28-70mm F2.8 DG DN | Contemporary is based on the 24-70mm F2.8 DG DN | Art, which is renowned for its outstanding optical performance across the entire focal length range. The 28-70mm F2.8 DG DN | Contemporary follows the core concept of the Contemporary product line: it was designed to offer the right balance of performance and handiness. In a body that is light enough for everyday use, this fast standard zoom lens thus delivers outstanding image quality that rivals lenses in the Art product line.
Outstanding build quality with attention to detail
The body of the SIGMA 28-70mm F2.8 DG DN | Contemporary, which was designed to be portable above all else, consists primarily of lightweight components.
Although conventional wisdom holds that it is more difficult to ensure processing accuracy with plastic parts than with metal parts, no compromises were made in the processing quality of the 28-70mm F2.8 DG DN | Contemporary. One reason for this is the use of the special polycarbonate TSC (Thermally Stable Composite), which has comparable thermal shrinkage to aluminum. This reduces the differences in thermal shrinkage between metallic and non-metallic components, ensuring consistent performance even under extreme temperature fluctuations. The use of polycarbonates in the construction of zoom and focus rings can make them appear less premium in practice. However, when these parts are carefully machined for precision and appropriately adjusted in motion by lubricants, the rings provide precise mechanics with an exceptionally high-quality feel.
Highest Optical Performance
The 28-70mm F2.8 DG DN | Contemporary makes use of state-of-the-art technology and features a modern optical design that includes three aspherical, two FLD and two SLD elements.
Despite the overall lower number of elements than the 24-70mm F2.8 DG DN | Art, the design still results in extensive correction of longitudinal chromatic aberration and sagital coma that cannot be corrected by camera. This allows users to create images that are consistently sharp from the center to the edge of the shot. In addition to the anti-ghosting design, the Super Multi-Layer and Nano-Porous coatings ensure well-controlled flare for high-contrast results even when backlit. The front lens of the Lens features a water- and oil-repellent coating.
The Everyday Companion
The SIGMA 28-70mm F2.8 DG DN | Contemporary offers a new and improved photographic experience to mirrorless camera photographers who need a fast standard zoom lens. Its high-quality, intuitive construction makes the lens as exciting to use as the incredible images it can produce - inspiring you to realize its creative potential.
Ghosting and Reflection Minimizing Design
An ideal lens directs incident light through all the lenses and onto the sensor. If, on the other hand, some of the light is reflected by individual lenses, not only does the light yield decrease; the reflections within the Lens create ghost images and aperture spots, or they reduce contrast. Such effects would be particularly noticeable in backlit shots.
To prevent this, our 28-70mm F2.8 DG DN | Contemporary uses Super Multi-Layer Coating (SML) and Nano Porous Coating, which reduce flare and ghosting. The result is clear, sharp, high-contrast images without distracting lens flares.
Compatible with the latest full-frame mirrorless cameras
The 28-70mm F2.8 DG DN | Contemporary is compatible with full-frame mirrorless cameras with L-mount or Sony E-mount.
A stepper motor is used for fast focusing. The autofocus with automatic eye detection used in newer mirrorless cameras is also supported; this makes precise focusing of portraits, for example, child's play.
With impressive image quality in 33 megapixel resolution, video recording in 4K 60p, precise handling and fast sharing functions, the Sony Alpha 7 IV sets new standards for full-frame cameras as the perfect hybrid camera.
