Panasonic LX100 versus Panasonic GM5

The Panasonic Lumix DMC-LX100 and the Panasonic Lumix DMC-GM5 are two digital cameras that were announced in September 2014. The LX100 is a fixed lens compact, while the GM5 is a mirrorless interchangeable lens camera. Both cameras are equipped with a Four Thirds sensor. The LX100 has a resolution of 12.7 megapixel, whereas the GM5 provides 15.8 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Panasonic LX100 vs Panasonic GM5

The physical size and weight of the Panasonic LX100 and the Panasonic GM5 are illustrated in the side-by-side display below. Three consecutive perspectives from the front, the top, and the back are presented. All width, height and depth dimensions are rounded to the nearest millimeter. You can also use the toggle button to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left – the LX100 – represents 100 percent across all the size and weight measures).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic GM5 is notably smaller (22 percent) than the Panasonic LX100. In this context, it is worth noting that neither the LX100 nor the GM5 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the LX100 has a lens build 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 find an overview of optics for the GM5 and their specifications in the Micro Four Thirds Lens Catalog.

Concerning battery life, the LX100 gets 300 shots out of its DMW-BLG10 battery, while the GM5 can take 220 images on a single charge of its DMW-BLH7 power pack.

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. 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.

Sensor comparison: Panasonic LX100 vs Panasonic GM5

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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its background. On the downside, larger sensors tend to be more expensive and 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.

Panasonic LX100 and Panasonic GM5 sensor measures

While the two cameras under review share the same sensor size, the GM5 offers a higher resolution of 15.8 megapixel, compared with 12.7 MP of the LX100. This megapixel advantage translates into a 12 percent gain in linear resolution. On the other hand, these sensor specs imply that the GM5 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.77μm versus 4.21μm 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.

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the LX100 or the GM5 handle or perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased. This is why hands-on reviews by experts are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
