General

About This Camera

Panasonic's 2025 Lumix S1R II is a full frame mirrorless camera built around a 44.3 megapixel sensor. It belongs in the high resolution class, a fit for photographers who crop heavily, print large or want room to reframe after the shot.

The video specification is equally ambitious, reaching 8K, so the camera suits anyone who wants detailed stills and demanding footage from a single body.

Carrying it takes some commitment: the camera comes in at 712 grams, worth factoring into travel plans and long handheld sessions.

Video

About the Video

The headline recording option is 8K at 30p, supplied with a 14 stop dynamic range figure. That range gives anyone grading footage real latitude to recover highlights and lift shadows without the image falling apart.

For everyday projects, 4K 60p records in 4:2:2 10-bit, a sampling depth that holds up well through grading. When you need slow motion, 4K 120p is available, though a 1.1x crop slightly narrows the field of view.

Open gate recording captures a wide 6.4K frame that can be reframed for different delivery ratios. Panasonic lists 8.1K and 7.2K open gate modes for future firmware, so 6.4K is the option available now.

Internal 5.8K ProRes RAW HQ recording removes the need for an external recorder when you want maximum flexibility in post, which keeps the rig simpler on location.

Optics

About the Optics

The full frame sensor's high resolution defines the stills experience. Files carry enough detail for large prints, and heavy cropping still leaves room to spare for tighter compositions or straightened horizons. For photographers who reframe after capture, that margin is the main practical payoff.

In-body stabilisation shifts the sensor to counter camera shake, helping handheld shots stay sharp at shutter speeds you would otherwise avoid. Because the mechanism sits in the body, it works with any lens you mount rather than depending on stabilised glass. It does not freeze a moving subject, so it helps most with static scenes, landscapes and interiors.

Framing runs through an electronic viewfinder, which shows exposure and colour changes as you adjust settings before the shutter fires. That live preview lets you judge the result in the moment instead of checking the back of the camera afterwards, and it fits the mirrorless design, which offers no optical viewing path.

About the Features

Sealing against dust and moisture lets the S1R II keep working through changing outdoor conditions, which matters for landscape and travel shoots where you cannot choose your weather. It resists the elements rather than repelling them, so it still deserves care in sustained heavy rain.

Wi-Fi is built in, so images can leave the camera without a cable. For photographers who hand off work soon after capture, that wireless link is the practical upshot, useful while still on location.

Both features align with the rest of the camera. A high resolution body built for landscape and detail work is the natural beneficiary of dust and moisture sealing, and built-in Wi-Fi rounds out a camera that already handles demanding stills and 8K video.
