Sony a7 a7 IV Black 2021 Review

The Sony a7 IV is one of the best hybrid cameras you can buy, with killer autofocus, strong battery life, and versatile 4K video. The 33MP sensor is fine, not groundbreaking, and the 4K60 crop is a pain. But for the money (especially around $1,800), it's a top pick for creators who don't want to compromise much.

The Sony a7 IV is that rare camera that doesn't force you to pick sides. It's got a 33MP full-frame sensor that's solid for stills and more than enough for most video work, plus an autofocus system that just sticks to subjects like glue. 759 AF points, real-time eye tracking for humans and animals, and a fast 10fps burst make it feel snappy and modern in the hand. And with a fully articulating touchscreen and a crisp 3.7M-dot EVF, it's built to help you shoot however you like.

But the real trick is the video side: 4K 60p in 10-bit with S-Cinetone color, a full-size HDMI port, and support for XAVC HS and S-I codecs. It's a content creator's dream, whether you're vlogging, streaming, or shooting short films. The in-body stabilization isn't the strongest ever, but it's good for handheld footage. All this in a weather-sealed body that weighs about 658g, so it's portable without feeling flimsy.

The autofocus is best-in-class, plain and simple. It locks on instantly and barely lets go, which is a lifesaver for fast-moving subjects or run-and-gun video work. 10fps burst shooting puts it right in the middle of the pack, fine for most action but not class-leading. The battery life is a real standout: 520 shots per charge is near the top of the charts for mirrorless cameras. Video quality is impressive with that 10-bit 4K, though you'll face a Super35 crop when shooting 60p, which can be a hassle if you need wide-angle shots. The sensor resolution is about average for today's full-frame market, but it's plenty for almost anything you'd throw at it. For product photography, however, it's a bit underwhelming compared to higher-resolution rivals.

Pricing for the a7 IV is all over the place across retailers, ranging from around $1,771 to a baffling $321,986. At the low end, it's a fantastic value for a hybrid camera that does this much. You're getting professional-level video features, top-tier autofocus, and access to Sony's massive E-mount lens library. If you can snag it near the $1,800 mark, it's a steal. Just avoid the wildly inflated listings, and maybe factor in an external charger and an extra battery.

Against the Canon EOS R6 Mark III, the a7 IV holds its own with a higher-res sensor and a broader range of affordable third-party lenses, though Canon's ergonomics and menus feel more refined. The Panasonic GH7 is a video beast with uncropped 4K60 and internal ProRes, but it's stuck in Micro Four Thirds world, so low-light and depth of field control aren't as strong. Nikon's Z9 is in another league for speed and video, but it's huge, heavy, and way more expensive. The Fujifilm X-H2S is a fast APS-C alternative with fantastic film simulations, but you lose full-frame dynamic range. The OM System OM-1 Mark II is lighter and tougher, but its smaller sensor can't match the Sony's image quality in mixed light. For a balanced hybrid, the a7 IV still sits near the top of the pile.

If you need a dedicated product photography camera with high resolution and fine detail rendering, this isn't it, our numbers show it's just mediocre there. People who despise menu diving and want the most comfortable grip around should seriously consider the Canon R6 Mark III instead. And if uncropped 4K60 is non-negotiable, Panasonic or an a7S III are better bets.

If you're a hybrid shooter who splits time between photos and videos, the a7 IV should be on your shortlist. It's a camera that feels at home in a studio, on a gimbal, or hanging from a strap at a wedding. Streamers, YouTubers, and multi-hyphenate creatives will love the autofocus and 10-bit color. Just know that it's not a specialist's tool: product photographers might want more resolution, and videographers who demand uncropped 4K60 will need to look elsewhere.
