Panasonic Lumix DMC-GM1 Mirrorless MFT (Micro Four Thirds) Camera Body, Silver/Black {16MP}

The GM1 packs a real Micro Four Thirds sensor into a coat-pocket body.

At 99 x 55 x 30mm and 204 grams, the GM1 is genuinely pocketable in a way that most interchangeable-lens cameras are not. Panasonic didn't simply shrink an existing design, the entire body was engineered from scratch to hit these dimensions without gutting the sensor. The 16MP Four Thirds CMOS is the same generation used in the full-featured GX7, which means image quality doesn't follow the size downward. RAW support is included, and the ISO range runs from a boosted 125 up to 25600, giving shooters real latitude in mixed or low light.

The shutter system is worth understanding before you buy. The mechanical curtain tops out at 1/500 sec, but the electronic shutter reaches 1/16000 sec, useful for shooting wide open in bright conditions without a ND filter. The 3-inch touchscreen resolves at 1,036,000 dots, which is a notably sharp panel for navigating menus or reviewing RAW files in the field. Burst shooting runs at 5 fps across 23 AF points, which covers most situations outside fast-action sports.

The Micro Four Thirds mount is the real long-term argument here. The entire Panasonic and Olympus lens ecosystems are on the table, including Sigma's MFT offerings, fast primes, telephoto zooms, macro glass. A camera this small with that much glass behind it is a specific kind of useful that fixed-lens compacts simply can't match.

Who It's For

Travel photographers who are serious about image quality but unwilling to carry a larger kit will appreciate the GM1's full MFT mount in a body that fits a jacket pocket. Street photographers benefit from the low-profile rangefinder form factor and the electronic shutter's silent 1/16000 sec ceiling, which eliminates mechanical noise and handles harsh midday light. Existing Micro Four Thirds shooters looking for a compact second body can mount any lens already in their bag. Photographers stepping up from a point-and-shoot get RAW files, full manual exposure control, and a sensor meaningfully larger than any fixed-lens compact in this size class.

FAQ

How does the GM1's 16MP sensor compare to other pocket cameras?

It's a Four Thirds CMOS - substantially larger than the 1-inch sensors in cameras like the Sony RX100 II, which means better depth-of-field control and cleaner high-ISO files. Same sensor generation as the GX7, so image quality tracks with a full-featured Micro Four Thirds body, not a point-and-shoot.

What's the practical difference between the 1/500 mechanical shutter and 1/16000 electronic shutter?

The mechanical shutter handles normal shooting; the electronic shutter lets you shoot wide open in bright sun without a ND filter, and gives you faster flash sync than the 1/50 mechanical limit would otherwise allow.

Does the GM1 have an electronic viewfinder?

No viewfinder at all - it's touchscreen LCD only. The 3-inch 1,036,000-dot screen is sharp enough for reviewing RAW files in the field, but you're working off the rear panel in bright light.

Which lenses work with the GM1?

Any Micro Four Thirds mount lens - the full Panasonic and Olympus catalogs plus Sigma's MFT offerings. A 2x focal length multiplier applies, so a 50mm becomes a 100mm equivalent. Larger lenses may protrude below the body; Panasonic sells an optional grip plate that lets them sit flush.

What's the battery life realistically?

230 shots per charge on CIPA rating with the kit lens. That's lean for an interchangeable-lens camera, but expected given the small battery required to keep the body pocket-sized. Bring a spare.

Can I record 1080/60p video?

Maximum is 1080/60i (interlaced). Panasonic also offers 1080/24p, 720/60p, and lower resolutions - MPEG-4 and AVCHD formats, stereo audio from the top-mounted mic.

Does the GM1 have Wi-Fi?

Built-in Wi-Fi (802.11 b/g/n), no NFC. Micro HDMI and USB 2.0 for wired connectivity. No external microphone jack or hot shoe.
