Sony Cyber-Shot DSC-RX10 III Digital Camera, Black {20.1MP}

RX10 III: 24-600mm f/2.4 superzoom in a weather-sealed body.

The RX10 III packages a 25x optical zoom spanning 24-600mm equivalent into a single weather-sealed body, and that lens opens to f/2.4 at the wide end. Reaching 600mm without changing glass is the defining reason to consider this camera, and Sony pairs it with a 20.1MP 1-inch stacked CMOS sensor and Bionz X processor. The electronic shutter hits 1/32000 sec, giving you room to shoot wide open in daylight without reaching for a filter.

Video shooters get 4K at up to 30p via XAVC S, 1080p at up to 120fps, and high-frame-rate modes that reach 240, 480, and 960fps for extreme slow-motion work. A headphone port and microphone input make this a workable solo production tool. The 2.36-million-dot EVF covers 100% of the frame, and the tilting 3-inch LCD adds flexibility for low and overhead angles.

Burst shooting tops out at 14fps in Speed Priority mode, with continuous AF available at 5fps. ISO runs 64-25600 in expanded range, and optical SteadyShot stabilization lets you handhold at the 600mm end at shutter speeds well below what physics would normally allow. For a fixed-lens camera, the RX10 III remains a genuinely serious tool for anyone who needs reach, weather sealing, and video capability without assembling a multi-lens kit.

Who It's For

Wildlife and birding photographers working from fixed positions get an effective 600mm reach with optical stabilization and burst shooting without any lens swap. Travel documentarians who need both wide establishing shots and compressed telephoto coverage in a single carry-on-friendly body will find the 24-600mm range covers almost every situation. Sports photographers shooting from the sidelines at predictable angles can exploit the 14fps Speed Priority burst and face-detection AF to build usable sequences. Videographers doing solo event or nature work benefit from 4K recording, S-Log 2 picture profiles, and the dedicated audio ports for a clean, self-contained production setup.

FAQ

What's the effective range of the 24-600mm lens, and is it really usable at 600mm?

The 24-600mm equivalent range covers everything from wide landscapes to extreme telephoto work. At 600mm, you'll get tight framing on distant subjects, but optical stabilization and the electronic shutter (1/32000 sec) make handheld shooting feasible. Expect to handhold at speeds around 1/60th or faster with stabilization on.

Can I shoot RAW, and what's the burst rate?

Yes, RAW is available. Burst rates depend on mode: 5fps in Continuous AF, 14fps in Speed Priority (though RAW slows this to roughly 8fps). You'll get usable bursts of at least three seconds before the camera throttles.

Does the camera have weather sealing, and what about the viewfinder?

The body is weather-sealed. The electronic viewfinder covers 100% of the frame at 2.36 million dots, so framing and focus confirmation are clear across the entire image.

What are the video capabilities, especially for slow-motion work?

4K records at up to 30p (XAVC S format). For slow-motion, you get 1080p at 120fps, plus extreme high-frame-rate modes at 240fps, 480fps, and 960fps. Headphone and microphone ports are built in, making solo video production viable.

Why was the built-in ND filter removed from the earlier model?

The RX10 II had a 3-stop built-in ND; the Mark III dropped it in favor of a longer zoom lens. The electronic shutter reaches 1/32000 sec, which largely compensates for daylight shooting at wide apertures. For video, you'll want to add an external ND filter to control shutter speeds properly.

How does autofocus perform, especially at telephoto distances?

The camera uses contrast-detect AF with 25 points. It's fast and accurate for static subjects, but struggles with low-contrast scenes and moving subjects at extreme telephoto-the lack of phase-detection AF means it can hunt at 600mm. Direct manual focus and lock-on AF tracking are available if you need them.

What's the ISO range, and how does it perform in low light?

Native ISO runs 100-12800; boosted range extends to 64-25600. The 20.1MP 1-inch sensor performs well at higher ISOs without excessive noise, making handheld shooting in dim conditions practical.
