Compare MX-1 versus RX1R top
Comparison MX-1 or RX1R rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony RX1R is somewhat smaller (1 percent) than the Pentax MX-1. However, the RX1R is markedly heavier (23 percent) than the MX-1. In this context, it is worth noting that neither the MX-1 nor the RX1R are weather-sealed.

The power pack in the RX1R 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.

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 82 percent) than the RX1R, which puts it into a different 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.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants 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 more expensive and 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 Sony RX1R a full frame sensor. The sensor area in the RX1R is 1891 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 4.5 and 1.0. The sensor in the MX-1 has a native 4:3 aspect ratio, while the one in the RX1R offers a 3:2 aspect.

Pentax MX-1 and Sony RX1R sensor measures

With 24MP, the RX1R offers a higher resolution than the MX-1 (12MP), but the RX1R nevertheless has larger individual pixels (pixel pitch of 5.97μm versus 1.89μm for the MX-1) due to its larger sensor. Moreover, the RX1R is a somewhat more recent model (by 5 months) than the MX-1, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the RX1R has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Sony RX1R implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the RX1R for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 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 Sony Cyber-shot DSC-RX1R are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 50-102400.

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.

MX-1 versus RX1R MP

For many cameras, data on sensor performance has been reported by DXO Mark. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. Of the two cameras under consideration, the RX1R offers substantially better image quality than the MX-1 (overall score 42 points higher). The advantage is based on 4.6 bits higher color depth, 2.3 EV in additional dynamic range, and 3.6 stops in additional low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The MX-1 and the RX1R 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 RX1R can be equipped with an optional viewfinder – the FDA-EV1MK. The adjacent table lists some of the other core features of the Pentax MX-1 and Sony RX1R along with similar information for a selection of comparators.

The MX-1 is equipped with a zoom lens, while the RX1R comes with a built-in prime. The MX-1 has a 28-112mm f/1.8-2.5 optic and the RX1R offers a 35mm f/2.0 (focal lengths in full frame equivalent terms). Hence, the Pentax provides a wider angle of view at the short end, as well as more tele-photo reach at the long end than the Sony. The MX-1 offers the faster maximum aperture.

The MX-1 writes its imaging data to SDXC cards, while the RX1R uses SDXC or Memory Stick PRO Duo cards.

It is notable that the RX1R has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The MX-1 does not feature such a mic input.

Both the MX-1 and the RX1R have been discontinued, but can regularly be found used on ebay. The RX1R was replaced by the Sony RX1R II, while the MX-1 does not have a direct successor. Further information on the features and operation of the MX-1 and RX1R can be found, respectively, in the Pentax MX-1 Manual (free pdf) or the online Sony RX1R Manual.

Review summary

So what conclusions can be drawn? Is there a clear favorite between the Pentax MX-1 and the Sony RX1R? Which camera is better? The listing below highlights the relative strengths of the two models.

ilogo

Advantages of the Pentax MX-1:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • 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.
  • Better light gathering: Has a lens with a wider maximum aperture (f/1.8 vs f/2.0).
  • Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
  • Less heavy: Is lighter (by 91g or 19 percent) and hence easier to carry around.
  • Sharper images: Has hand-shake reducing image stabilization built-in.
  • More affordable: Was introduced into a lower priced category (82 percent cheaper at launch).
  • More heavily discounted: Has been on the market for longer (launched in January 2013).

ilogo

Arguments in favor of the Sony Cyber-shot DSC-RX1R:

  • More detail: Has more megapixels (24 vs 12MP), which boosts linear resolution by 44%.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Better image quality: Scores substantially higher (42 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (4.6 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (2.3 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (3.6 stops ISO advantage).
  • Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
  • Better sound: Can connect to an external microphone for higher quality sound recording.
  • More framing options: Can be equipped with a hotshoe-mounted accessory-viewfinder.
  • More detailed LCD: Has a higher resolution rear screen (1229k vs 920k dots).
  • Faster burst: Shoots at higher frequency (5 vs 1 flaps/sec) to capture the decisive moment.
  • Easier travel charging: Can be conveniently charged via its USB port.
  • Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
  • More modern: Was introduced somewhat (5 months) more recently.

If the number of relative strengths (bullet points above) is taken as a guide, the RX1R is the clear winner of the contest (14 : 9 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. A professional wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

MX-1 09:14 RX1R

How about other alternatives? Do the specifications of the Pentax MX-1 and the Sony RX1R place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera and Best Prime Lens Compact 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 partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the MX-1 or the RX1R. 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.

Expert reviews

This is where reviews by experts come in. The adjacent summary-table relays the overall verdicts of several of the most popular camera 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.

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
