Who the Sony a7 IV is for

The Sony a7 IV is a 33MP full-frame mirrorless camera, a versatile all-rounder.

A 33MP full-frame hybrid that became the benchmark all-rounder for enthusiasts, succeeding the long-running a7 III.
Real-time Eye AF for humans, animals and birds with reliable subject tracking across stills and video.
4K 10-bit internal recording, in-body stabilization and a vari-angle screen aimed at hybrid shooters.

Best for

Video and filmmaking — 4K up to 60p, 10-bit internal and Log.
Vlogging and handheld video — flip-out screen and a mic input.
Travel and the outdoors — in-body stabilisation plus weather sealing.
Low-light and events — a large full-frame sensor and ISO to 51,200.

Keep in mind

Single card slot — no in-camera backup, which matters for critical paid jobs.

What Full-Frame means in practice

A full-frame sensor at 33MP gives the shallowest depth of field of the three formats at any given framing and aperture, and the most sensor area to gather light with. That is the physical reason full-frame bodies tend to be the larger and heavier option: the lenses that cover the format have to be bigger too.

Video, stabilisation and weather sealing

4K runs to 60p, giving headroom for smooth motion or a modest slow-motion cut. 10-bit recording internally means colour survives grading rather than banding when pushed. A log profile is available, which trades a flat-looking file for latitude in post.

In-body stabilisation steadies any lens mounted on it, including primes with no stabilisation of their own. The body is weather-sealed.
