Sony Alpha a7 IV Black 2021 Review

The Sony a7 IV is a brilliant hybrid that nails photos and video, as long as you don't ask it to record a feature-length film. Buy it for the autofocus, stay for the image quality.

The Sony a7 IV is the Swiss Army knife of full-frame mirrorless cameras, and for most hybrid shooters, it's still the one to beat. It combines a rich 33MP sensor, mind-reading autofocus, and beautiful 4K video into a body that feels just right. But there's a catch: push the video too long and it'll overheat faster than a phone on a dashboard. If you're cool with that trade-off, this camera is an absolute powerhouse.

The 33MP sensor lands in our database at a middling 59th percentile for raw resolution, but don't let that fool you. Day-to-day, it punches well above its weight with gorgeous color and dynamic range. What truly shocked us, though, is the autofocus. With 759 phase-detect points and real-time tracking that snags eyes like a magnet, it's close to best-in-class. The battery life is also a standout, consistently exceeding the 500-shot rating in real-world use. For video, the 4K 60p footage is crisp and detailed, though the camera tends to wave a white flag after around 30 minutes of continuous recording, cutting power to cool down.

At around $1,700 from reputable dealers, the a7 IV is a steal for a full-frame hybrid this capable. But we've seen prices as absurd as $628,213 from some third-party sellers, so please don't get scammed. For what you're getting (stellar AF, strong video features, and that huge E-mount lens library), it's absolutely worth it. Just buy it from a real store, not a scalper.

The Canon EOS R6 Mark III gives it a run for its money with better burst speeds and less whining about heat, but Sony's autofocus and lens selection still edge it out for most people. If you really need resolution, the Fujifilm X-H2 packs a 40MP sensor into a crop body and costs less, but you sacrifice that full-frame look. The Nikon Z9 is a different beast entirely, meant for pros who can justify its size and price tag. For a compact, do-everything camera, the a7 IV is the sweet spot.

If you're looking for a dedicated video workhorse, this isn't it. The overheating will drive you nuts. Grab a Panasonic LUMIX GH7 or a Sony FX3 instead. And if you're a resolution purist printing billboards, a higher-megapixel body like the Sony a7R V makes more sense.

The Sony a7 IV is the hybrid camera to get right now if you split your time evenly between photos and video. It's not flawless (that overheating issue is real), but for stills and short video clips, it's a joy. If your workflow demands long, uninterrupted recording, look at a dedicated video body. For everyone else, this is the one.
