Panasonic GM5 vs LX100
The Panasonic Lumix DMC-GM5 and the Panasonic Lumix DMC-LX100 are two digital cameras that were revealed to the public in September 2014. The GM5 is a mirrorless interchangeable lens camera, while the LX100 is a fixed lens compact. Both cameras are equipped with a Four Thirds sensor. The GM5 has a resolution of 15.8 megapixels, whereas the LX100 provides 12.7 MP.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.
Going beyond this snapshot of core features and characteristics, what are the differences between the Panasonic Lumix DMC-GM5 and the Panasonic Lumix DMC-LX100? 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 physical size and weight of the Panasonic GM5 and the Panasonic LX100 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth measures are rounded to the nearest millimeter.
Both cameras are available in two different colors (black, silver).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic LX100 is notably larger (28 percent) than the Panasonic GM5. In this context, it is worth noting that neither the GM5 nor the LX100 are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the LX100 has a lens built in, whereas the GM5 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the GM5 and their specifications in the Micro Four Thirds Lens Catalog.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

Any camera decision will obviously take relative prices into account. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. 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 imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 tend to be associated with larger, more expensive camera bodies and lenses.
Both cameras under consideration feature a Four Thirds sensor, but their sensors differ slightly in size. The sensor area in the LX100 is 18 percent smaller. As a result of these sensor size differences, the cameras have format factors, respectively, of 2.0 (GM5) and 2.2. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3. The LX100 has the particularity of featuring a switch that allows to toggle between multiple aspect ratios, while maintaining the same field of view and full image resolution.
With 15.8MP, the GM5 offers a higher resolution than the LX100 (12.7MP), but the GM5 has marginally smaller individual pixels (pixel pitch of 3.77μm versus 3.82μm for the LX100). It is noteworthy in this context that the two cameras were released in close succession, so that their sensors are from the same technological generation.
The resolution advantage of the Panasonic GM5 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GM5 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 LX100 are 20.6 x 15.4 inches or 52.2 x 39.2 cm for good quality, 16.4 x 12.4 inches or 41.8 x 31.4 cm for very good quality, and 13.7 x 10.3 inches or 34.8 x 26.1 cm for excellent quality prints.
The Panasonic Lumix DMC-GM5 has a native sensitivity range from ISO 200 to ISO 25600, which can be extended to ISO 100-25600. The Panasonic Lumix DMC-LX100 offers exactly the same ISO settings.
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. The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the LX100 provides a better video resolution than the GM5. It can shoot movie footage at 4K/30p, while the GM5 is limited to 1080/60p.
Beyond body and sensor, cameras can and do differ across a range of features. The two cameras under review are similar with respect to both having an electronic viewfinder. However, the one in the LX100 offers a substantially higher resolution than the one in the GM5 (2764k vs 1166k dots). The following table reports on some other key feature differences and similarities of the Panasonic GM5, the Panasonic LX100, and comparable cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The GM5 has a touchscreen, while the LX100 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, both cameras under consideration feature an 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 GM5 and the Panasonic LX100 both have 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 GM5 and the LX100 write their files to SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.
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-GM5 and Panasonic Lumix DMC-LX100 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

The LX100 is a recent model that features in the current product line-up of Panasonic. In contrast, the GM5 has been discontinued (but can be found pre-owned on eBay). There has not been a direct replacement model for the GM5 from Panasonic. 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 how do things add up? Which of the two cameras – the Panasonic GM5 or the Panasonic LX100 – 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.
Reasons to prefer the Panasonic Lumix DMC-GM5:
- More detail: Offers more megapixels (15.8 vs 12.7MP) with a 12% higher linear resolution.
- Better low-light sensitivity: Requires less light for good images (0.4 stops ISO advantage).
- Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
- More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
- More compact: Is smaller (99x60mm vs 115x66mm) and thus needs less room in the bag.
Arguments in favor of the Panasonic Lumix DMC-LX100:
- More dynamic range: Captures a broader range of light and dark details (0.8 EV of extra DR).
- Flexible image proportions: Has a multi-aspect sensor that allows for alternative image shapes.
- Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
- More detailed viewfinder: Has higher resolution electronic viewfinder (2764k vs 1166k dots).
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.70x vs 0.46x).
- Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/500s) to freeze action.
- Faster burst: Shoots at higher frequency (11 vs 5.8 flaps/sec) to capture the decisive moment.
- Ready to shoot: Has an integrated lens, whereas the GM5 necessitates an extra lens.
- Longer lasting: Gets more shots (300 versus 220) out of a single battery charge.
- Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
- Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
If the number of relative strengths (bullet points above) is taken as a guide, the LX100 is the clear winner of the contest (11 : 5 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision. A professional wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports 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 GM5 and the Panasonic LX100 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best Travel-Zoom Camera listings whether the two cameras rank among the cream of the crop.
In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it says little about, for example, the shooting experience and imaging performance of the GM5 and the LX100 in practical situations. 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 review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
