The Sony A7 IV is the most-deployed prosumer full-frame mirrorless in adult video production as of 2026. 33-megapixel sensor, 4K 60p (with crop), 10-bit 4:2:2 internal recording, robust autofocus with eye-detection that works through scenes. Released 2021, still current. Body-only $2,500 new; commonly available used in the $1,800–$2,100 range.
Why it became the default. Strong combination of video specs, photo capability (paysite content frequently needs both video and stills from the same shoot), autofocus reliability for moving subjects, and a mature lens ecosystem (Sony E-mount native plus extensive third-party support from Sigma, Tamron, and others). The ergonomics improved meaningfully over earlier A7-series bodies; operators who hesitated on previous-generation Sonys often committed at A7 IV.
What to pair it with. A standard zoom (24–70 f/2.8 or 28–75 f/2.8) for primary work; an 85mm or 85–105 prime for portrait-style framing; a 35mm or 24mm prime for POV and tight-quarters work. Add proper lighting, a microphone, and a tripod or gimbal depending on style.
Limitations. The 4K 60p mode applies a Super35 crop — on a full-frame body that costs you wide-angle reach at high frame rates. The internal ProRes-equivalent codecs are not present (if you need that, the A7S III or the newer A1/A9 III are different tools).
Bottom line. Default prosumer body for adult video production in 2026. See our camera comparison for budget-tier alternatives and the broader equipment context.
