Going beyond this snapshot of core features and characteristics, what are the differences between the Pentax MX-1 and the Leica C-LUX? 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.

Body comparison

The physical size and weight of the Pentax MX-1 and the Leica C-LUX are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth measures are rounded to the nearest millimeter.

The C-LUX can be obtained in two different colors (gold, blue), while the MX-1 is only available in black.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Leica C-LUX is somewhat larger (2 percent) than the Pentax MX-1. However, the C-LUX is markedly lighter (13 percent) than the MX-1. In this context, it is worth noting that neither the MX-1 nor the C-LUX are weather-sealed.

The power pack in the C-LUX can be charged via the USB port, which can be very convenient when travelling.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

Any camera decision will obviously take relative prices into account. 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 MX-1 was launched at a markedly lower price (by 52 percent) than the C-LUX, which puts it into a different market segment. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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.

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.

Of the two cameras under consideration, the Pentax MX-1 features a 1/1.7-inch sensor and the Leica C-LUX an one-inch sensor. The sensor area in the C-LUX is 170 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 4.5 and 2.7. The sensor in the MX-1 has a native 4:3 aspect ratio, while the one in the C-LUX offers a 3:2 aspect.

With 20MP, the C-LUX offers a higher resolution than the MX-1 (12MP), but the C-LUX nevertheless has larger individual pixels (pixel pitch of 2.41μm versus 1.89μm for the MX-1) due to its larger sensor. Moreover, the C-LUX is a much more recent model (by 5 years and 5 months) than the MX-1, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.

The resolution advantage of the Leica C-LUX implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the C-LUX for good quality output (200 dots per inch) amounts to 27.4 x 18.2 inches or 69.5 x 46.3 cm, for very good quality (250 dpi) 21.9 x 14.6 inches or 55.6 x 37.1 cm, and for excellent quality (300 dpi) 18.2 x 12.2 inches or 46.3 x 30.9 cm. The corresponding values for the Pentax MX-1 are 20 x 15 inches or 50.8 x 38.1 cm for good quality, 16 x 12 inches or 40.6 x 30.5 cm for very good quality, and 13.3 x 10 inches or 33.9 x 25.4 cm for excellent quality prints.

The Pentax MX-1 has a native sensitivity range from ISO 100 to ISO 12800. The corresponding ISO settings for the Leica C-LUX are ISO 125 to ISO 12800, with the possibility to increase the ISO range to 80-25600.

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.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 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 C-LUX provides a better video resolution than the MX-1. It can shoot movie footage at 4K/30p, while the Pentax is limited to 1080/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the C-LUX has an electronic viewfinder (2330k dots), which can be very helpful when shooting in bright sunlight. In contrast, the MX-1 relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Pentax MX-1 and Leica C-LUX in connection with corresponding information for a sample of similar cameras.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The C-LUX has a touchscreen, while the MX-1 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, the C-LUX is one of those camera that have an additional 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 Leica C-LUX 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 MX-1 and the C-LUX have zoom lenses built in. The MX-1 has a 28-112mm f/1.8-2.5 optic and the C-LUX offers a 24-360mm f/3.3-6.4 (focal lengths in full frame equivalent terms). Hence, the Leica provides a wider angle of view at the short end, as well as more tele-photo reach at the long end than the Pentax. The MX-1 offers the faster maximum aperture.

Concerning the storage of imaging data, both the MX-1 and the C-LUX write their files to SDXC cards. The C-LUX supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the MX-1 cannot take advantage of Ultra High Speed SD 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 Pentax MX-1 and Leica C-LUX and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the C-LUX offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the MX-1 does not provide wifi capability.

Both the MX-1 and the C-LUX have been discontinued, but can regularly be found used on ebay. Neither of the two has a direct successor, so they represent the end of the respective camera lines from Pentax and Leica. Further information on the features and operation of the MX-1 and C-LUX can be found, respectively, in the Pentax MX-1 Manual (free pdf) or the online Leica C-LUX Manual.

Review summary

So what is the bottom line? Is there a clear favorite between the Pentax MX-1 and the Leica C-LUX? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

Advantages of the Pentax MX-1:

If the count of relative strengths (bullet points above) is taken as a measure, the C-LUX is the clear winner of the contest (21 : 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape 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 Pentax MX-1 and the Leica C-LUX place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera and Best Superzoom 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 remains incomplete and does no justice, for example, to the way the MX-1 or the C-LUX 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.

The review scores listed above should be treated with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
