Note: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

The price is, of course, an important factor in any camera decision. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The two cameras under review were launched at the same price and fall into the same 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.

Sensor comparison

The size of the imaging sensor is a crucial determinant 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Both cameras under consideration feature a 1/1.7-inch sensor, but their sensors differ slightly in size. The sensor area in the MX-1 is 2 percent bigger. As a result of these sensor size differences, the cameras have format factors, respectively, of 4.65 (LX7) and 4.5. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3. The LX7 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.

Panasonic LX7 and Pentax MX-1 sensor measures

With 12MP, the MX-1 offers a higher resolution than the LX7 (10MP), but the MX-1 has smaller individual pixels (pixel pitch of 1.89μm versus 2.05μm for the LX7). Yet, the MX-1 is a somewhat more recent model (by 5 months) than the LX7, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.

The resolution advantage of the Pentax MX-1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the MX-1 for good quality output (200 dots per inch) amounts to 20 x 15 inches or 50.8 x 38.1 cm, for very good quality (250 dpi) 16 x 12 inches or 40.6 x 30.5 cm, and for excellent quality (300 dpi) 13.3 x 10 inches or 33.9 x 25.4 cm. The corresponding values for the Panasonic LX7 are 18.2 x 13.7 inches or 46.3 x 34.7 cm for good quality, 14.6 x 10.9 inches or 37.1 x 27.8 cm for very good quality, and 12.2 x 9.1 inches or 30.9 x 23.2 cm for excellent quality prints.

The Panasonic Lumix DMC-LX7 has a native sensitivity range from ISO 80 to ISO 6400, which can be extended to ISO 80-12800. The corresponding ISO settings for the Pentax MX-1 are ISO 100 to ISO 12800 (no boost).

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

LX7 versus MX-1 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 imaging performance. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras cannot only take still pictures, but also record videos. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the LX7 provides a higher frame rate than the MX-1. It can shoot video footage at 1080/60p, while the Pentax is limited to 1080/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The LX7 and the MX-1 are similar in the sense that neither of the two has a viewfinder. The images are, thus, framed using live view on the rear LCD. That said, the LX7 can be equipped with an optional viewfinder – the DMW-LVF2. The following table reports on some other key feature differences and similarities of the Panasonic LX7, the Pentax MX-1, and comparable cameras.

The Panasonic LX7 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.

Both the LX7 and the MX-1 have zoom lenses built in. The LX7 has a 24-90mm f/1.4-2.3 optic and the MX-1 offers a 28-112mm f/1.8-2.5 (focal lengths in full frame equivalent terms). Hence, the Panasonic provides a wider angle of view at the short end than the Pentax, but less tele-photo reach at the long end. The LX7 offers the faster maximum aperture.

Concerning the storage of imaging data, both the LX7 and the MX-1 write their files to SDXC cards.

Connectivity comparison

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-LX7 and Pentax MX-1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the LX7 has a hotshoe, while the MX-1 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

Both the LX7 and the MX-1 have been discontinued, but can regularly be found used on ebay. The LX7 was replaced by the Panasonic LX10, while the MX-1 does not have a direct successor. Further information on the features and operation of the LX7 and MX-1 can be found, respectively, in the Panasonic LX7 Manual (free pdf) or the online Pentax MX-1 Manual.

Review summary

So how do things add up? Is the Panasonic LX7 better than the Pentax MX-1 or vice versa? The listing below highlights the relative strengths of the two models.

ilogo

Reasons to prefer the Panasonic Lumix DMC-LX7:

  • Flexible image proportions: Has a multi-aspect sensor that allows for alternative image shapes.
  • Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
  • More framing options: Can be equipped with a hotshoe-mounted accessory-viewfinder.
  • Faster burst: Shoots at higher frequency (11 vs 1 flaps/sec) to capture the decisive moment.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • Better light gathering: Has a lens with a wider maximum aperture (f/1.4 vs f/1.8).
  • Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
  • Less heavy: Is lighter (by 93g or 24 percent) and hence easier to carry around.
  • Longer lasting: Can take more shots (330 versus 290) on a single battery charge.
  • Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
  • More heavily discounted: Has been on the market for longer (launched in July 2012).

ilogo

Arguments in favor of the Pentax MX-1:

  • More detail: Has more megapixels (12 vs 10MP), which boosts linear resolution by 10%.
  • Better low-light sensitivity: Can shoot in dim conditions (0.5 stops ISO advantage).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
  • More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
  • More modern: Was introduced somewhat (5 months) more recently.

If the count of relative strengths (bullet points above) is taken as a measure, the LX7 is the clear winner of the match-up (11 : 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 wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

LX7 11:06 MX-1

How about other alternatives? Do the specifications of the Panasonic LX7 and the Pentax MX-1 place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera listing 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 remains incomplete and does no justice, for example, to the way the LX7 or the MX-1 perform in practice. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.

Expert reviews

This is why hands-on reviews by experts are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). 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.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

Care should be taken when interpreting the review scores above, though. The ratings are only valid when referring to cameras in the same category and of the same age. A score, therefore, has to be seen in close connection to the price and market introduction time 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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
