Pentax MX-1 vs Olympus E-M5

The Pentax MX-1 and the Olympus OM-D E-M5 are two digital cameras that were officially introduced, respectively, in January 2013 and February 2012. The MX-1 is a fixed lens compact, while the E-M5 is a mirrorless interchangeable lens camera. The cameras are based on a 1/1.7-inch (MX-1) and a Four Thirds (E-M5) sensor. The Pentax has a resolution of 12 megapixels, whereas the Olympus provides 15.9 MP.

Below is an overview of the main specs of the two cameras as a starting point for the comparison.

Going beyond this snapshot of core features and characteristics, what are the differences between the Pentax MX-1 and the Olympus OM-D E-M5? 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

An illustration of the physical size and weight of the Pentax MX-1 and the Olympus E-M5 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth dimensions are rounded to the nearest millimeter.

The E-M5 can be obtained in two different colors (black, silver), while the MX-1 is only available in black.

Compare MX-1 versus E-M5 top
Comparison MX-1 or E-M5 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-M5 is considerably larger (46 percent) than the Pentax MX-1. It is noteworthy in this context that the E-M5 is splash and dust-proof, while the MX-1 does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the MX-1 has a lens built in, whereas the E-M5 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the E-M5 and their specifications in the Micro Four Thirds Lens Catalog.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

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

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 lower price than the E-M5, despite having a lens built in. 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. 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. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have 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 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 Olympus E-M5 a Four Thirds sensor. The sensor area in the E-M5 is 423 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 4.5 and 2.0. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

In terms of underlying technology, both cameras are build around CMOS sensors.

Pentax MX-1 and Olympus E-M5 sensor measures

With 15.9MP, the E-M5 offers a higher resolution than the MX-1 (12MP), but the E-M5 nevertheless has larger individual pixels (pixel pitch of 3.76μm versus 1.89μm for the MX-1) due to its larger sensor. However, the MX-1 is a somewhat more recent model (by 10 months) than the E-M5, 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 Olympus E-M5 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the E-M5 for good quality output (200 dots per inch) amounts to 23 x 17.3 inch or 58.5 x 43.9 cm, for very good quality (250 dpi) 18.4 x 13.8 inch or 46.8 x 35.1 cm, and for excellent quality (300 dpi) 15.4 x 11.5 inch or 39 x 29.3 cm. The corresponding values for the Pentax MX-1 are 20 x 15 inch or 50.8 x 38.1 cm for good quality, 16 x 12 inch or 40.6 x 30.5 cm for very good quality, and 13.3 x 10 inch 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 Olympus OM-D E-M5 are ISO 200 to ISO 25600 (no boost).

MX-1 versus E-M5 MP

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"). Of the two cameras under consideration, the E-M5 offers substantially better image quality than the MX-1 (overall score 22 points higher). The advantage is based on 2.4 bits higher color depth, 1 EV in additional dynamic range, and 2 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.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the E-M5 provides a faster frame rate than the MX-1. It can shoot movie footage at 1080/60i, 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 E-M5 has an electronic viewfinder (1440k 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 following table reports on some other key feature differences and similarities of the Pentax MX-1, the Olympus E-M5, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The MX-1 has one, while the E-M5 does not. While the built-in flash of the MX-1 is not very powerful, it can at times be useful as a fill-in light.

Concerning the storage of imaging data, both the MX-1 and the E-M5 write their files to SDXC cards. The E-M5 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 Olympus OM-D E-M5 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the E-M5 has a hotshoe, which makes it possible to easily attach optional accessories, such as an external flash gun. The MX-1 does not feature such an accessory-socket.

Both the MX-1 and the E-M5 have been discontinued, but can regularly be found used on eBay. The E-M5 was replaced by the Olympus E-M5 II, while the MX-1 does not have a direct successor. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Pentax and Olympus websites.


Review summary

So what is the bottom line? Is the Pentax MX-1 better than the Olympus E-M5 or vice versa? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Reasons to prefer the Pentax MX-1:

  • More detailed LCD: Has a higher resolution rear screen (920k vs 610k dots).
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
  • Ready to shoot: Has a lens built-in, whereas the E-M5 requires a separate lens.
  • More compact: Is smaller (122x61mm vs 122x89mm) and thus needs less room in the bag.
  • Less heavy: Is lighter even though it comes with a built-in lens (unlike the E-M5).
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
  • More affordable: Was introduced at a lower price, despite coming with a built-in lens.
  • More modern: Is somewhat more recent (announced 10 months after the E-M5).

ilogo

Arguments in favor of the Olympus OM-D E-M5:

  • More detail: Has more megapixels (15.9 vs 12MP), which boosts linear resolution by 15%.
  • Better image quality: Scores substantially higher (22 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (2.4 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (1 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (2 stops ISO advantage).
  • Better video: Provides higher movie framerates (1080/60i versus 1080/30p).
  • Easier framing: Has an electronic viewfinder for image composition and settings control.
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • Faster burst: Shoots at higher frequency (9 vs 1 flaps/sec) to capture the decisive moment.
  • More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
  • Longer lasting: Gets more shots (360 versus 290) out of a single battery charge.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
  • Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
  • More heavily discounted: Has been on the market for longer (launched in February 2012).

If the count of relative strengths (bullet points above) is taken as a measure, the E-M5 is the clear winner of the contest (15 : 8 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.

MX-1 08:15 E-M5

How about other alternatives? Do the specifications of the Pentax MX-1 and the Olympus E-M5 place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera and Best Mirrorless Interchangeable Lens Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the MX-1 and the E-M5 in practical situations. 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 why expert reviews are important. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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.

The above review scores should be interpreted with care, 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 comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
