The Sony a7 IV does double duty with strong stills and video performance. An advanced hybrid mirrorless camera, the a7 IV has the resolution and AF performance that appeals to photographers along with robust 4K 60p video recording for filmmakers and content creators. This design benefits working in low-light conditions and works in conjunction with a broad sensitivity range of ISO 100-51200. The sensor's design also achieves an impressive dynamic range of approximately 15 stops and files can be recorded in raw, JPEG, or the 10-bit HEIF format. The quick processing also helps to reduce rolling shutter and other motion distortions for the clean rendering of moving subjects. This design benefits working in low-light conditions and works in conjunction with a broad sensitivity range of ISO 100-51200.

The sensor's design also achieves an impressive dynamic range of approximately 15 stops and files can be recorded in raw, JPEG, or the 10-bit HEIF format. The quick processing also helps to reduce rolling shutter and other motion distortions for the clean rendering of moving subjects. Also, the buffer permits recording up to 828 consecutive uncompressed raw + JPEG frames when using a CFexpress Type A card. Making full use of the high-resolution 33MP sensor and fast processing capabilities, UHD 4K 30p XAVC HS 10-bit recording is possible using the full width of the sensor, offering 7K oversampling for impressive sharpness and realism. No recording time limit allows for unlimited clip lengths and the camera's physical design features an improved heat-dissipating structure to promote longer possible recording times; longer than one hour of continuous 4K 60p 10-bit 4:2:2 recording, for example. HLG (Hybrid Log-Gamma) support permits recording within a wide color gamut for producing HDR-ready content directly from the camera. 

This focusing system is available for use in all recording modes, to benefit both video and still applications. Real-time Tracking is an AI-based subject recognition system that recognizes color, pattern, and subject distance information for high accuracy and focusing speed. Real-time Eye AF even maintains focus on a subject's eye when they leave and re-enter the frame, allowing for working in more spontaneous shooting situations. For more control over how focus shifts appear during recording, seven-step AF transition speeds and five-step AF subject shift sensitivity controls let you refine how quickly focus shifts from point to point and how smoothly focusing shifts occur. This viewfinder supports both standard 60 fps and 120 fps frame rates for smooth motion rendering and its physical design has a long 23mm eyepoint, 0.78x-magnification, and 37.3° field of view. 

The FE 28-70mm f/3.5-5.6 OSS Lens from Sony is a great go-to for full-frame E-mount shooters. The lens uses a variable f/3.5-5.6 maximum aperture range in order to achieve a lightweight and compact size and incorporates one extra-low dispersion element and three aspherical elements to minimize aberrations throughout the range. Also, it has a linear motor and internal focus that enable fast, reliable autofocusing. On top of this, the lens offers built-in Optical SteadyShot image stabilization to combat the effects of camera shake. One extra-low dispersion glass element is featured in the lens design to help reduce chromatic aberrations and color fringing for improved clarity and color neutrality. An internal focus mechanism and linear motor contribute to a faster, more responsive system and easier handling. Dust- and moisture-sealed design better permits working in inclement conditions and rubberized control rings benefit handling in colder temperatures.
