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

An illustration of the physical size and weight of the Panasonic LX100 and the Panasonic GM5 is provided in the side-by-side display below. 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. 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 the basis or 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 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 imaging sensor is at the core of digital cameras and its size is one of the main determining factors of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units 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 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. The LX100 has the particularity of featuring a switch that allows to toggle between different aspect ratios, while maintaining the same field of view and full image resolution.

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.

LX100 versus GM5 MP

For many cameras, data on sensor performance has been reported by DXO Mark. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar image quality. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the LX100 provides a higher video resolution than the GM5. It can shoot video footage at 4K/30p, while the GM5 is limited to 1080/60p.

 

Feature comparison: Panasonic LX100 vs Panasonic GM5

Beyond body and sensor, cameras can and do differ across a range of features. The two cameras under consideration 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 table below summarizes some of the other core capabilities of the Panasonic LX100 and Panasonic GM5 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 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 and shutter burst refer to the use of the mechanical shutter. In addition, both cameras feature an electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (rolling shutter) or shooting under artificial light sources (flickering).

Both the LX100 and the GM5 write their imaging data to SDXC cards.

Review summary: Panasonic LX100 vs Panasonic GM5

So what conclusions can be drawn? Is the Panasonic LX100 better than the Panasonic GM5 or vice versa? Below is a summary of the relative strengths of each of the two contestants.


Advantages of the Panasonic Lumix DMC-LX100:

  • More dynamic range: Captures a larger spectrum 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).
  • Faster shutter: Has higher mechanical shutter speed (4000/sec vs 500/sec) to freeze action.
  • Faster burst: Shoots at higher frequency (11 vs 5.8 flaps/sec) to capture the decisive moment.
  • Ready to shoot: Has a lens build-in, whereas the GM5 requires a separate lens.
  • Longer lasting: Can take more shots (300 versus 220) on a single battery charge.
  • Sharper images: Has hand-shake reducing image stabilization build-in.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.


Reasons to prefer the Panasonic Lumix DMC-GM5:

  • More detail: Has more megapixels (15.8 vs 12.7MP), which boosts linear resolution by 12%.
  • Better low-light sensitivity: Can shoot in dim conditions (0.4 stops ISO advantage).
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
  • More compact: Is smaller (99x60mm vs 115x66mm) and will fit more readily into a bag.

If the count of relative strengths (bullet points above) is taken as a measure, the LX100 is the clear winner of the match-up (10 : 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.

LX100 10:05 GM5

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the LX100 or the GM5. 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 adjacent table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

Care should be taken when interpreting the review scores above, though. The assessments were made in relation to similar cameras of the same technological generation. Thus, a score needs to be put into the context of the launch date and the launch price 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.
