Panasonic LX100 versus Panasonic GX7

The Panasonic Lumix DMC-LX100 and the Panasonic Lumix DMC-GX7 are two enthusiast cameras that were officially introduced, respectively, in September 2014 and August 2013. The LX100 is a fixed lens compact, while the GX7 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 GX7 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 GX7

The physical size and weight of the Panasonic LX100 and the Panasonic GX7 are illustrated in the side-by-side display below. Three consecutive views from the front, the top, and the rear side are shown. All size 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 GX7 is notably larger (15 percent) than the Panasonic LX100. In this context, it is worth noting that neither the LX100 nor the GX7 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 GX7 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 GX7 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 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 LX100 was launched at a lower price than the GX7, despite having a lens build in. 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 GX7

The size of the imaging sensor is a crucial determinant 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 tend to be associated with larger, more expensive camera bodies 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 GX7 sensor measures

While the two cameras under review share the same sensor size, the GX7 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 GX7 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). Moreover, it should be noted, that the LX100 is a somewhat more recent model (by 1 year and 1 month) than the GX7, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of individual pixels.

LX100 versus GX7 MP

For most cameras, data on sensor performance has been reported by DXO Mark. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar image quality. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

The LX100 is a current model that online retailers, such as amazon, will have in stock. In contrast, the GX7 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the GX7 was succeeded by the Panasonic GX85.

Review summary: Panasonic LX100 vs Panasonic GX7

So how do things add up? Is the Panasonic LX100 better than the Panasonic GX7 or vice versa? A synthesis of the relative strong points of each of the models is listed below.


Reasons to prefer the Panasonic Lumix DMC-LX100:

  • Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
  • Faster burst: Shoots at higher frequency (11 vs 5 flaps/sec) to capture the decisive moment.
  • Ready to shoot: Has a lens build-in, whereas the GX7 requires a separate lens.
  • More compact: Is smaller (115x66mm vs 123x71mm) and thus needs less room in the bag.
  • Less heavy: Is lighter even though it comes with a build-in lens (unlike the GX7).
  • More affordable: Was introduced at a lower price, despite coming with a build-in lens.
  • More modern: Is somewhat more recent (announced 1 year and 1 month after the GX7).


Advantages of the Panasonic Lumix DMC-GX7:

  • 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).
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 921k dots).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
  • Longer lasting: Gets more shots (350 versus 300) out of a single battery charge.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • More heavily discounted: Has been on the market for longer (launched in August 2013).

If the number of relative strengths (bullet points above) is taken as a guide, the GX7 emerges as the winner of the match-up (10 : 7 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision on a new camera.

LX100 07:10 GX7

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the LX100 or the GX7 handle or perform in practice. 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 rankings of the cameras as published by some of the major 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 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.
