Going beyond this snapshot of core features and characteristics, what are the differences between the Panasonic Lumix DMC-G10 and the Panasonic Lumix DMC-GM1? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.
The side-by-side display below illustrates the physical size and weight of the Panasonic G10 and the Panasonic GM1. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth measures are rounded to the nearest millimeter.
The GM1 can be obtained in three different colors (black, silver, red), while the G10 is only available in black.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic GM1 is considerably smaller (48 percent) than the Panasonic G10. Moreover, the GM1 is substantially lighter (47 percent) than the G10. In this context, it is worth noting that neither the G10 nor the GM1 are weather-sealed.
The above size and weight comparisons are to some extent incomplete since they do not consider the interchangeable lenses that both of these cameras require. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can compare the optics available in the Micro Four Thirds Lens Catalog. Mirrorless cameras, such as the two under consideration, have the additional advantage of having a short flange to focal plane distance, which makes it possible to mount many lenses from other systems onto the camera via adapters.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The G10 was launched at a markedly lower price (by 33 percent) than the GM1, which puts it into a different market segment. Usually, retail prices stay at first close to the launch price, but after several months, discounts become available. Later in the product cycle and, in particular, when the replacement model is about to appear, further discounting and stock clearance sales often push the camera price considerably down. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
The size of the sensor inside a digital camera is one of the key determinants of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixels in a sensor of the same technological generation. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to isolate a subject from the background. On the downside, larger sensors are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Both cameras under consideration feature a Four Thirds sensor and have a format factor (sometimes also referred to as "crop factor") of 2.0. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.
While the two cameras under review share the same sensor size, the GM1 offers a higher resolution of 15.8 megapixels, compared with 12 MP of the G10. This megapixels advantage translates into a 15 percent gain in linear resolution. On the other hand, these sensor specs imply that the GM1 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.77μm versus 4.33μm for the G10). However, it should be noted that the GM1 is much more recent (by 3 years and 7 months) than the G10, and its sensor will have benefitted from technological advances during this time that compensate for the smaller pixel size.
The resolution advantage of the Panasonic GM1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GM1 for good quality output (200 dots per inch) amounts to 23 x 17.2 inches or 58.3 x 43.8 cm, for very good quality (250 dpi) 18.4 x 13.8 inches or 46.7 x 35 cm, and for excellent quality (300 dpi) 15.3 x 11.5 inches or 38.9 x 29.2 cm. The corresponding values for the Panasonic G10 are 20 x 15 inches or 50.8 x 38.1 cm for good quality, 16 x 12 inches or 40.6 x 30.5 cm for very good quality, and 13.3 x 10 inches or 33.9 x 25.4 cm for excellent quality prints.
The Panasonic Lumix DMC-G10 has a native sensitivity range from ISO 100 to ISO 6400. The corresponding ISO settings for the Panasonic Lumix DMC-GM1 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 125-25600.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. Of the two cameras under consideration, the GM1 offers substantially better image quality than the G10 (overall score 14 points higher). The advantage is based on 1.1 bits higher color depth, 1.6 EV in additional dynamic range, and 0.7 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the GM1 provides a better video resolution than the G10. It can shoot movie footage at 1080/60i, while the G10 is limited to 720/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the G10 has an electronic viewfinder (202k dots), which can be very helpful when shooting in bright sunlight. In contrast, the GM1 relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Panasonic G10 and Panasonic GM1 in connection with corresponding information for a sample of similar cameras.
One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The GM1 has a touchscreen, while the G10 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.
The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the GM1 is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).
The Panasonic GM1 has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.
Concerning the storage of imaging data, both the G10 and the GM1 write their files to SDXC cards. The GM1 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the G10 cannot take advantage of Ultra High Speed SD cards.
For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Panasonic Lumix DMC-G10 and Panasonic Lumix DMC-GM1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the G10 has a hotshoe, while the GM1 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.
Both the G10 and the GM1 have been discontinued, but can regularly be found used on eBay. The G10 was replaced by the Panasonic G3, while the GM1 was followed by the Panasonic GM5. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Panasonic website.
So what is the bottom line? Which of the two cameras – the Panasonic G10 or the Panasonic GM1 – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.
Advantages of the Panasonic Lumix DMC-G10:
- Easier framing: Has an electronic viewfinder for image composition and settings control.
- Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/500s) to freeze action.
- Longer lasting: Can take more shots (380 versus 230) on a single battery charge.
- Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
- More affordable: Was introduced into a lower priced category (33 percent cheaper at launch).
- More heavily discounted: Has been available for much longer (launched in March 2010).
Reasons to prefer the Panasonic Lumix DMC-GM1:
- More detail: Has more megapixels (15.8 vs 12MP), which boosts linear resolution by 15%.
- Better image quality: Scores substantially higher (14 points) in the DXO overall evaluation.
- Richer colors: Generates noticeably more natural colors (1.1 bits more color depth).
- More dynamic range: Captures a broader range of light and dark details (1.6 EV of extra DR).
- Better low-light sensitivity: Can shoot in dim conditions (0.7 stops ISO advantage).
- Better video: Provides higher definition movie capture (1080/60i vs 720/30p).
- More detailed LCD: Has a higher resolution rear screen (1036k vs 460k dots).
- Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
- Faster burst: Shoots at higher frequency (5 vs 2.6 flaps/sec) to capture the decisive moment.
- Less disturbing: Has an electronic shutter option for completely silent shooting.
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- More compact: Is smaller (99x55mm vs 124x84mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 184g or 47 percent) and is thus easier to take along.
- Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
- Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
- More modern: Reflects 3 years and 7 months of technical progress since the G10 launch.
If the count of individual advantages (bullet points above) is taken as a guide, the GM1 is the clear winner of the contest (16 : 6 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera. A professional sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape shooter. Hence, the decision which camera is best and worth buying is often a very personal one.
How about other alternatives? Do the specifications of the Panasonic G10 and the Panasonic GM1 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera listing whether the two cameras rank among the cream of the crop.
In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the G10 or the GM1. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.
This is why expert reviews are important. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier point that a camera decision is often a very personal choice.

The above review scores should be interpreted with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
