Olympus E-PL1 vs Pentax Q
The Olympus PEN E-PL1 and the Pentax Q are two digital cameras that were officially introduced, respectively, in February 2010 and June 2011. Both the E-PL1 and the Pentax Q are mirrorless interchangeable lens cameras that are based on a Four Thirds (E-PL1) and a 1/2.3-inch (Pentax Q) sensor. The Olympus has a resolution of 12.2 megapixels, whereas the Pentax provides 12 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 Olympus PEN E-PL1 and the Pentax Q? 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.
The physical size and weight of the Olympus E-PL1 and the Pentax Q are illustrated 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 size dimensions are rounded to the nearest millimeter.
The E-PL1 can be obtained in four different colors (black, blue, yellow, white), while the Pentax Q is available in two color-versions (black, white).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Pentax Q is considerably smaller (33 percent) than the Olympus E-PL1. Moreover, the Pentax Q is substantially lighter (46 percent) than the E-PL1. In this context, it is worth noting that neither the E-PL1 nor the Pentax Q are weather-sealed.
The above size and weight comparisons are to some extent incomplete since they do not consider the interchangeable lenses that both of these cameras require. Hence, you might want to study and compare the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.
The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. 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 naturally be influenced heavily by the price. 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 E-PL1 was somewhat cheaper (by 8 percent) than the Pentax Q at launch, but both cameras fall into the same price category. 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.
The size of the sensor inside a digital camera is one of the key determinants 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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to isolate a subject from the 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 Olympus E-PL1 features a Four Thirds sensor and the Pentax Q a 1/2.3-inch sensor. The sensor area in the Pentax Q is 88 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 5.6. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.
Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.
With 12.2MP, the E-PL1 offers a slightly higher resolution than the Pentax Q (12MP), but the E-PL1 nevertheless has larger individual pixels (pixel pitch of 4.29μm versus 1.53μm for the Pentax Q) due to its larger sensor. However, the Pentax Q is a somewhat more recent model (by 1 year and 4 months) than the E-PL1, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels.
The Olympus PEN E-PL1 has a native sensitivity range from ISO 200 to ISO 3200. The corresponding ISO settings for the Pentax Q are ISO 125 to ISO 6400 (no boost).
For many 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"). Of the two cameras under review, the E-PL1 has a notably higher overall DXO score than the Pentax Q (overall score 7 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 1.3 bits higher color depth, 1 EV of lower dynamic range, and 1.4 stops in additional low light sensitivity. 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 are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the Pentax Q provides a better video resolution than the E-PL1. It can shoot movie footage at 1080/30p, while the Olympus is limited to 720/30p.
Beyond body and sensor, cameras can and do differ across a range of features. The E-PL1 and the Pentax Q 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. However, optional viewfinders – the VF-2 for the E-PL1 and the O-VF1 for the Pentax Q – are available as accessories. The adjacent table lists some of the other core features of the Olympus E-PL1 and Pentax Q along with similar information for a selection of comparators.
The Pentax Q 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.
The E-PL1 writes its imaging data to SDHC cards, while the Pentax Q uses SDXC cards.
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 Olympus PEN E-PL1 and Pentax Q and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the E-PL1 and the Pentax Q have been discontinued, but can regularly be found used on eBay. The E-PL1 was replaced by the Olympus E-PL2, while the Pentax Q was followed by the Pentax Q10. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Olympus and Pentax websites.
So how do things add up? Which of the two cameras – the Olympus E-PL1 or the Pentax Q – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.
Advantages of the Olympus PEN E-PL1:
- Better image quality: Scores markedly higher (7 points) in the DXO overall assessment.
- Richer colors: Generates images with noticeably better colors (1.3 bits more color depth).
- Better low-light sensitivity: Requires less light for good images (1.4 stops ISO advantage).
- Faster burst: Shoots at higher frequency (3 vs 1.5 flaps/sec) to capture the decisive moment.
- Longer lasting: Can take more shots (290 versus 230) on a single battery charge.
- More heavily discounted: Has been on the market for longer (launched in February 2010).
Arguments in favor of the Pentax Q:
- More dynamic range: Captures a broader range of light and dark details (1 EV of extra DR).
- Better video: Provides higher definition movie capture (1080/30p vs 720/30p).
- Larger screen: Has a bigger rear LCD (3.0" vs 2.7") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (460k vs 230k dots).
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- More compact: Is smaller (98x57mm vs 115x72mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 154g or 46 percent) and is thus easier to take along.
- More modern: Was introduced somewhat (1 year and 4 months) more recently.
If the number of relative strengths (bullet points above) is taken as a guide, the Pentax Q emerges as the winner of the match-up (8 : 6 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 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.

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 E-PL1 or the Pentax Q 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.
This is where reviews by experts come in. The table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (amateurphotographer [AP], cameralabs [CL], 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 assessments were made in relation to similar cameras of the same technological generation. A score, therefore, has to be seen in close connection to the price and market introduction time 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.
