Panasonic Lumix DMC-ZS100 Digital Camera, Silver {20.1MP}

20MP 1-inch compact with 25-250mm reach and built-in EVF

The ZS100 answers a specific question: what if a jacket-pocket travel camera had a genuinely large sensor? Panasonic's answer is a 20.1MP 1-inch BSI CMOS sensor paired with a 25-250mm equivalent f/2.8 zoom, all in a body measuring 111 x 65 x 44mm and weighing 312g. That sensor advantage over smaller-sensor travel zooms is roughly two stops of light-gathering at equivalent focal lengths, which translates directly to cleaner files at higher ISOs and meaningfully more background separation in portraits.

The feature set runs deep for a camera this size. A built-in electronic viewfinder with 100% coverage handles bright-light shooting. RAW capture gives you full post-processing control. The electronic shutter reaches 1/16000 sec, and continuous shooting hits 10 fps. Panasonic's Post Focus mode, which racks focus across a scene and lets you select your focal point after the fact via the 3-inch touchscreen, is a genuinely useful tool than a novelty. 4K UHD video at 30p pairs with 5-axis hybrid optical stabilization in movie mode, making this a capable handheld video platform at a fraction of the bulk of a dedicated video rig.

ISO runs from 80 to 25600 in expanded mode, and the Depth from Defocus autofocus system tracked subjects reliably in real-world testing. Four customizable physical buttons plus five virtual ones mean you can build a control layout that fits how you actually shoot. For anyone who has outgrown a smartphone camera but refuses to carry a bag just to bring a camera, the ZS100 represents a considered trade-off: real sensor performance and real zoom range in a body that disappears into a coat pocket.

Who It's For

Travel photographers who want 250mm reach without checking a bag will find the ZS100's 10x optical zoom and 312g body a workable daily companion. Documentary and street shooters benefit from the 10 fps burst rate and Depth from Defocus autofocus for fast, unobtrusive shooting. Videographers shooting run-and-gun content get 4K UHD at 30p with 5-axis hybrid stabilization in a pocketable form factor. Photographers moving up from smartphone cameras who want RAW files, manual exposure modes, and a built-in EVF will find the 1-inch sensor delivers a measurable step up in image quality at improve ISOs.

FAQ

How does the ZS100's 1-inch sensor compare to smaller travel zoom cameras in low light?

The 1-inch BSI CMOS gathers roughly two stops more light than a 1/2.3-inch sensor at equivalent focal lengths, which means cleaner high-ISO files and better signal-to-noise ratio when you're forced to push ISO in dim conditions.

What is Post Focus and does it actually work?

Post Focus records a brief video clip while the camera racks focus across the scene, then lets you tap the LCD to select your focal point after capture and save that frame. It works reliably even with slight motion, and RAW is disabled when using it.

Can you use the electronic viewfinder for video?

Yes, the 100% coverage EVF works for video, but it's small (1.17M-dot equivalent with color tearing on pan) compared to competitors like the Sony RX100 III. Most shooters will prefer the 3-inch touchscreen for both stills and video work.

What's the autofocus system like for tracking moving subjects?

The 49-point Depth from Defocus AF system is genuinely fast and reliable for subject tracking. It's carried over from Panasonic's mirrorless cameras, and the touchscreen makes repositioning the focus point trivial.

Is the lens sharp across the frame at all focal lengths?

Center sharpness peaks around 70mm at f/5, and corner softness is the trade-off for fitting a 25-250mm zoom into a pocket body. Stopping to f/5.6 or f/8 gives more consistent results across the frame than shooting wide open.

How much can you customize the controls?

Extensively. Four physical buttons plus five virtual buttons can be reassigned, both lens and top dials are customizable, and the Quick Menu can be populated with any function. You can also place the histogram anywhere in the frame and set custom gridlines.

Does the 4K video stabilization actually work handheld?

The hybrid optical 5-axis stabilization in movie mode is effective for handheld 4K at 30p/24p. 1080/60p is also available, but the camera captures 4K reliably without a tripod in reasonable light.
