The Panasonic Lumix DMC-GM1 is the smallest interchangeable lens digital camera you can buy. It's not as full-featured as some other models, but you can't argue with its size or performance.

• +

  Very small. Crisp touch-screen LCD. Hinged flash. Snappy performer. 5fps continuous shooting. Clean images through ISO 1600. 1/16,000-second electronic shutter. Sharp, compact kit lens. Raw shooting support. Wi-Fi.

• -

  Fixed screen with no EVF option. Lacks accessory shoe or mic input. Compressed control layout. Kit lens lacks manual focus ring. Limited burst shooting in Raw.

Panasonic have achieved something quite remarkable with the GM1. The way such impressive features have been squeezed into such a small body goes to show what is possible, and as well as being a great technological achievement in its own right, its put its own stamp on what we define as compact in...

  Robust magnesium chassis; Premium finish; Full Manual control; Wi-fi; Excellent functionality within the Panasonic Image app; Pin-point AF; Touchscreen functionality; Live preview of Creative Filters

• -

  No viewfinder; Poor battery life; No headphone port for audio monitoring; USB battery charging not permitted; Lack of handgrip

Written down it sounds like Panasonic has scored a coup no-one else has thought of, but really the GM1 simply fulfills the promise of mirrorless system cameras when they were first introduced several years ago - namely to deliver DSLR quality, control and interchangeable lens flexibility in a...

  Great image quality, as good as the Lumix GX7., Fast AF which works in lower light than most cameras., Touchscreen lets you tap to focus for stills and movies., 1080 movies with 24p, manual exposures and peaking., Timelapse, 7-frame AEB, HDR modes, lots of effects.

• -

  Other lenses may prevent tripod use., No panorama mode., Rear control wheel easy to press when turning., No 1080 video at 50p or 60p., No hotshoe nor means to mount viewfinder or mic., Modest battery life and no USB charging.

The GM1 offers many of the features and image quality of its Lumix GX7 sibling in a much smaller, lighter package. A few concessions have been made to reduce the size so drastically, namely a lower-capacity battery, but it's an excellent option for casual shooting.

  Poor noise reduction, JPEG rendering of yellows a bit washed out, Low battery capacity, Small controls can be fiddly, Focus mode dial not especially useful, Electronic shutter can produce banding under artificial light, Video resolution tops out at 1080 30p, Default dynamic range settings produce...

Panasonic deserves a round of applause for designing a very compact and lightweight interchangeable lens camera. Overall, the camera is capable of taking good pictures, but performance is a bit uneven.

The Panasonic Lumix DMC-GM1KS is very small, even though it has an APS-C-sized sensor. The camera is smaller than Nikon’s 1 series and even a bit smaller than the Pentax Q series, which has a compact camera sensor.

The Panasonic Lumix DMC-GM1 squeezes excellent image-quality comparable to modern mirrorless digital cameras and fast performance into a compact camera-size body. This alone justifies this digital camera as a compelling offer. This mirrorless produces well-exposed images with low noise.

  Low image noise until ISO 1600, Well-balanced metering, Good color and WB, Speedy autofocus, Fast and highly responsive, Short shutter-lag, Instant video capture, Calibratable LCD, Extremely compact for a mirrorless

• -

  Slight image softness from base ISO, Dynamic-range not as wide as competition, Modal EC interface, Small cramped controls, Preview not always Exposure-Priority, Wrong Live-Histogram, Video clips last second, Poor battery-life

The general impression of the Lumix DMC-GM1 is a very positive one—it feels like nit picking to describe the battery life as so-so at just over 200 images, which is no better than a humble snapshot camera costing a quarter of the price.

• +

  Compact and sturdy, Diminutiveness doesn’t unduly affected handling, Great image quality

• -

  So-so battery life, Touch sensitive on-screen icons and physical buttons are small, No eye-level viewfinder

The Panasonic GM1 surprised us all upon first glance -- it's a Panasonic GX7, for the most part, all crammed into an insanely small, practically-pocketable body! Indeed, the GM1 packs a lot of horsepower, including the same 16MP Live MOS sensor and Venus Engine image processor as the larger GX7,...

  Extremely small and lightweight design with large, Four Thirds sensor, Ultra-portable camera and lens combo, Incredible image quality for the size, Excellent high ISO performance for its class, Compact kit lens is sharp, even wide-open, Uses standard Micro Four Thirds mount; lets you use the full...

  Small body can be difficult to hold with larger lenses, Very weak flash, No hotshoe for attaching external flash, EVF or microphone, Poor macro performance with kit lens, Touch-AF is slow to re-focus by itself, No body-based, sensor-shift image stabilization like GX7; relies on lens-based OIS,...

The Panasonic Lumix GM1 is a camera extraordinary in many respects. It has the best balance between size and image quality of all cameras currently on the market and offers a performance and a range of advanced features into a truly pocket-sized camera body.

• +

  Microscopic, Excellent image quality, Fast AF and accurate, Excellent gust.

  Sync flash at only 1/50s, Some controls are not immediate, Build quality is not flawless.

This is similar to the review I published on a different vendor's website. I've been searching for an interchangeable lens pocket camera with good image quality for a while now. I've used first a GF3 (limited IQ), then a GX1 (which I loved), and then a GF6.

This is a great camera but much smaller than the pictures show. It was too small for me to hold comfortably and securely. If like me, you have large hands, you may want to consider the size carefully. It can be especially difficult with lenses besides the kit lens.

My first m43 camera. After a months usage I am getting to grips with it and results are improving. The 12-32mm kit lens is excellent. Sharp edge to edge and the wide angle of 24mm is very useful for landscapes. I have been shooting Jpeg+Raw and find the jpeg engine to be very good.
