Panasonic Lumix S DC-S1MK Black 2021

The Panasonic Lumix S1 is a tank of a full-frame mirrorless camera with outstanding image quality and seriously good video features, especially after the V-Log firmware update. The 5.76M-dot EVF is one of the best we've seen, and the build quality is basically unmatched. At current street prices around $1,650, it's a steal for hybrid shooters who don't need a flip-out screen or class-leading autofocus. If you can handle the weight and don't mind a deliberate shooting style, this is a lot of camera for the money.

The 24.2MP sensor delivers image quality that owners consistently rave about, and our database backs that up with solid, middle-of-the-pack sensor performance. But the real story is what Panasonic's Venus Engine does with that data. The DFD contrast-detect autofocus system with 225 points is quick for stills, landing well above average in our rankings. It's not going to embarrass a stacked-sensor sports body, but for most people shooting portraits, landscapes, or events, it's more than capable. The 9fps mechanical burst rate is about average, so if you're deep into wildlife or fast action, you might feel a little constrained. For everyone else, it's plenty.

Video is where the S1 gets interesting. Out of the box you get 4K60p with 10-bit 4:2:0 internal recording, and a firmware update unlocks V-Log and 4:2:2 10-bit internal recording. That update, by the way, is a recurring theme among happy owners. It essentially transforms the camera into a much more serious video tool. The 5.5 stops of in-body stabilization is a standout, keeping handheld footage smooth and making those high-resolution stills sharp even in dicey light. The 5.76M-dot EVF is one of the best on the market, huge and crisp, which makes manual focusing a genuine pleasure.

Stacked against the Canon EOS R6 Mark III, the S1 gives you a better EVF and more robust build, but Canon's Dual Pixel autofocus is simply more reliable for video tracking. The Sony a7 V will be lighter and have a more mature lens ecosystem, but you'll likely pay more for comparable video specs. The Fujifilm X-H2 is a compelling APS-C alternative with higher resolution and faster burst rates, but you lose that full-frame depth of field and low-light advantage. And the Nikon Z9 is in a completely different stratosphere for speed and autofocus, but it's also much more expensive and even heavier. The S1 carves out a niche as the tank-like hybrid that prioritizes image quality and video features over outright speed or portability.

Pricing on the S1 is all over the map right now, with a spread from $1,650 to over a million dollars across vendors. Obviously, ignore the absurd high end. The real sweet spot is around that $1,650 mark, which is a frankly ridiculous deal for a full-frame camera with this video feature set and build quality. For context, that's less than many APS-C flagships. If you can find it at that price from a reputable seller, the value proposition is hard to beat. Just make sure you're getting a body that's ready for the firmware update, because that's what really unlocks its potential.

Panasonic's Lumix S1 is one of those cameras that feels like it was built to survive a minor apocalypse and still nail a 4K60 shot. It's a full-frame mirrorless workhorse aimed squarely at hybrid shooters who split their time evenly between stills and video, and who don't want to baby their gear. The magnesium alloy body is fully weather-sealed, and at just over a kilogram, it has a reassuring heft that screams durability. This isn't the lightest option for a day of street photography, but for studio work, event coverage, or shooting in rough conditions, the build quality is basically best-in-class. We're talking top of the charts here, and it feels like it.

Vloggers and solo content creators who need to see themselves while filming should probably look elsewhere. The triaxial tilt screen is fine for waist-level shooting, but it doesn't flip around to the front, and that's a dealbreaker for a lot of people. Combine that with autofocus that can hunt during video, and you've got a frustrating setup for self-shooting. A Canon EOS R6 Mark III or even a Sony ZV-E1 would serve you much better for that kind of work. Also, if you're a dedicated sports or wildlife photographer who needs blazing fast burst rates and sticky subject tracking, the S1's 9fps and contrast-detect AF will feel limiting. Look at a used Sony a9 or a Nikon Z8 instead.

If you're a hybrid shooter who values build quality and video features above all else, and you don't mind a little heft, the S1 is a phenomenal deal at current street prices. The image quality is lovely, the EVF is a joy, and that firmware update turns it into a legitimate filmmaking tool. It's a camera that rewards a deliberate, thoughtful shooting style. Pair it with the 24-105mm f/4 kit lens and you've got a weather-sealed setup that can handle almost anything.

But if you're a run-and-gun vlogger who needs reliable face tracking while walking and talking, or a sports photographer who needs 20+ fps bursts, this isn't your camera. The lack of a flip-out screen and the occasional autofocus wobbles during video will drive you nuts. For those use cases, look at the Canon R6 Mark III or a used Sony a7 IV. The S1 is for people who want a solid, dependable tool that excels at both stills and video, and who don't need the lightest or fastest option on the market.
