Olympus E-PL2 vs Pentax Q
The Olympus PEN E-PL2 and the Pentax Q are two digital cameras that were officially introduced, respectively, in January 2011 and June 2011. Both the E-PL2 and the Pentax Q are mirrorless interchangeable lens cameras that are based on a Four Thirds (E-PL2) 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-PL2 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.
Body comparison
The side-by-side display below illustrates the physical size and weight of the Olympus E-PL2 and the Pentax Q. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All size dimensions are rounded to the nearest millimeter.
The E-PL2 can be obtained in four different colors (black, silver, red, 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 (32 percent) than the Olympus E-PL2. Moreover, the Pentax Q is substantially lighter (50 percent) than the E-PL2. In this context, it is worth noting that neither the E-PL2 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 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 naturally be influenced heavily by the price. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The E-PL2 was somewhat cheaper (by 8 percent) than the Pentax Q at launch, but both cameras fall into the same price category. 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 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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better isolate a subject from the 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 Olympus E-PL2 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.
With 12.2MP, the E-PL2 offers a slightly higher resolution than the Pentax Q (12MP), but the E-PL2 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 5 months) than the E-PL2, 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-PL2 has a native sensitivity range from ISO 200 to ISO 6400. The corresponding ISO settings for the Pentax Q are ISO 125 to ISO 6400 (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.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 review, the E-PL2 has a notably higher overall DXO score than the Pentax Q (overall score 8 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 1.2 bits higher color depth, 0.9 EV of lower dynamic range, and 1.6 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the Pentax Q provides a better video resolution than the E-PL2. It can shoot movie footage at 1080/30p, while the Olympus is limited to 720/30p.
Feature comparison
Apart from body and sensor, cameras can and do differ across a range of features. The E-PL2 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-PL2 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-PL2 and Pentax Q along with similar information for a selection of comparators.

Further information on the features and operation of the E-PL2 and Pentax Q can be found, respectively, in the Olympus E-PL2 Manual (free pdf) or the online Pentax Q Manual.
Review summary
So how do things add up? Which of the two cameras – the Olympus E-PL2 or the Pentax Q – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.
Arguments in favor of the Olympus PEN E-PL2:
- Better image quality: Scores markedly higher (8 points) in the DXO overall assessment.
- Richer colors: Generates images with noticeably better colors (1.2 bits more color depth).
- Better low-light sensitivity: Requires less light for good images (1.6 stops ISO advantage).
- Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
- Faster burst: Shoots at higher frequency (3 vs 1.5 flaps/sec) to capture the decisive moment.
- Longer lasting: Can take more shots (280 versus 230) on a single battery charge.
- More heavily discounted: Has been on the market for longer (launched in January 2011).
Advantages of the Pentax Q:
- More dynamic range: Captures a broader range of light and dark details (0.9 EV of extra DR).
- Better video: Provides higher definition movie capture (1080/30p vs 720/30p).
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- More compact: Is smaller (98x57mm vs 114x72mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 182g or 50 percent) and is thus easier to take along.
- More modern: Was introduced somewhat (5 months) more recently.
If the count of relative strengths (bullet points above) is taken as a measure, the E-PL2 comes out slightly ahead of the Pentax Q (7 : 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.
How about other alternatives? Do the specifications of the Olympus E-PL2 and the Pentax Q place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera listing 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 remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the E-PL2 or the Pentax Q. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.
Expert reviews
This is why expert reviews are important. The following table reports the overall ratings of the cameras as published by some of the major 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 assessments were made in relation to similar cameras of the same technological generation. Thus, a score needs to be put into the context of the launch date and the launch price 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, please note that some of the review sites have changed their methodology and reporting over time.
