Conclusion: 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. With that said, we feel you’re giving up way too much in terms of quality and usability – especially for $750 MSRP. The 16MP MFT sensor just doesn’t deliver the detail you’d expect at this price level.
Excerpt: If you're a photographer who wants a camera that's the size of a point-and-shoot, but with the flexibility and larger sensor of an interchangeable lens camera, then the Panasonic GM1 might just be the camera for you. Panasonic has introduced the “micro-est” of Micro Four Thirds cameras with their diminutive yet powerful Lumix GM1 -- the latest addition to their already healthy lineup of Micro Four Thirds cameras.
Summary: 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. Moreover, unlike all the super-compact on the market (except for the Pentax Q7, which however, has a sensor far smaller), can accept interchangeable lenses, and then allows to choose between the whole range...
Pros: Microscopic, Excellent image quality, Fast AF and accurate, Excellent gust.
Cons: Sync flash at only 1/50s, Some controls are not immediate, Build quality is not flawless.
Summary: 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.
Pros: Extremely small and lightweight camera body, Very good image quality, Reliable transfer of image files over Wi-Fi, Truly silent shutter mode, Good touchscreen, Nice level of Q.menu and virtual Fn button customizability, Compatible with all Micro Four Thirds lenses, Kit zoom is highly compact with collapsible design, good image quality, Reliable iAuto mode for beginner/hands-off types
Cons: 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 slight highlight clipping, Slow 1/50 flash sync speed
Summary: 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 smaller body.
Pros: 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., Built-in Wifi with smartphone remote control., Silent shutter option with maximum speed of 1/16,000., Small, light kit zoom with 24mm wide angle and good quality., Compatible with extensive Micro Four Thir...
Cons: 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.
Conclusion: The littlest Lumix may be physically overshadowed by flagship M43 cameras, but it still manages to hang with the best of them. Discounting the quirky-cute but underperforming Pentax Q cameras, the GM1 is the most compact compact system camera—emphasis on system —we've seen yet. No other small camera provides photographers with such a wide array of options. The only limiting factor is how awkward this little thing can get with a honkin' huge lens attached.
Summary: 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 compact system camera.
Conclusion: It's interesting to see Panasonic marketing this camera squarely at the likes of the Sony RX100 II, which up until now has had fantastic success, while Panasonic's own premium compact (fixed lens) cameras have taken a bit of a backseat. Will all that change now? With a similar price point, it'll be interesting to see. Stay tuned.
