Olympus E-30 vs Pentax Q
The Olympus E-30 and the Pentax Q are two digital cameras that were officially introduced, respectively, in November 2008 and June 2011. The E-30 is a DSLR, while the Pentax Q is a mirrorless interchangeable lens camera. The cameras are based on a Four Thirds (E-30) 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 E-30 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
An illustration of the physical size and weight of the Olympus E-30 and the Pentax Q 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 measures are rounded to the nearest millimeter.
The Pentax Q can be obtained in two different colors (black, white), while the E-30 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 Pentax Q is considerably smaller (64 percent) than the Olympus E-30. Moreover, the Pentax Q is substantially lighter (74 percent) than the E-30. In this context, it is worth noting that neither the E-30 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.

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 Pentax Q was launched at a markedly lower price (by 50 percent) than the E-30, 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. 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 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-30 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-30 offers a slightly higher resolution than the Pentax Q (12MP), but the E-30 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 much more recent model (by 2 years and 7 months) than the E-30, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.
The Olympus E-30 has a native sensitivity range from ISO 100 to ISO 3200. 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.
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 review, the E-30 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 1.1 bits higher color depth, 0.7 EV of lower dynamic range, and 1.5 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. The Pentax Q indeed provides for movie recording, while the E-30 does not. The highest resolution format that the Pentax Q can use is 1080/30p.
Feature comparison
Apart from body and sensor, cameras can and do differ across a range of features. For example, the E-30 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the Pentax Q relies on live view and the rear LCD for framing. That said, the Pentax Q can be equipped with an optional viewfinder – the O-VF1. The table below summarizes some of the other core capabilities of the Olympus E-30 and Pentax Q in connection with corresponding information for a sample of similar cameras.

One feature that is present on the E-30, but is missing on the Pentax Q is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.
The E-30 has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the Pentax Q does not have a selfie-screen.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-30 writes its imaging data to Compact Flash or xD Picture cards, while the Pentax Q uses SDXC cards. The E-30 features dual card slots, which can be very useful in case a memory card fails. In contrast, the Pentax Q only has one slot.
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 Olympus E-30 and Pentax Q and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the E-30 and the Pentax Q have been discontinued, but can regularly be found used on ebay. The Pentax Q was replaced by the Pentax Q10, while the E-30 does not have a direct successor. Further information on the features and operation of the E-30 and Pentax Q can be found, respectively, in the Olympus E-30 Manual (free pdf) or the online Pentax Q Manual.
Review summary
So what conclusions can be drawn? Is the Olympus E-30 better than the Pentax Q or vice versa? The listing below highlights the relative strengths of the two models.
Advantages of the Olympus E-30:
- Better image quality: Scores markedly higher (8 points) in the DXO overall assessment.
- Richer colors: Generates images with noticeably better colors (1.1 bits more color depth).
- Better low-light sensitivity: Requires less light for good images (1.5 stops ISO advantage).
- Easier framing: Has an optical viewfinder for image composition and settings control.
- Easier setting verification: Features an LCD display on top to control shooting parameters.
- More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/2000s) to freeze action.
- Faster burst: Shoots at higher frequency (5 vs 1.5 flaps/sec) to capture the decisive moment.
- Longer lasting: Can take more shots (750 versus 230) on a single battery charge.
- Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
- More heavily discounted: Has been available for much longer (launched in November 2008).
Reasons to prefer the Pentax Q:
- More dynamic range: Captures a broader range of light and dark details (0.7 EV of extra DR).
- Broader imaging potential: Can capture not only stills but also 1080/30p video.
- 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 142x108mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 521g or 74 percent) and is thus easier to take along.
- More legacy lens friendly: Can use many non-native lenses via adapters.
- More affordable: Was introduced into a lower priced category (50 percent cheaper at launch).
- More modern: Reflects 2 years and 7 months of technical progress since the E-30 launch.
If the number of relative strengths (bullet points above) is taken as a guide, the E-30 emerges as the winner of the contest (12 : 10 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-30 and the Pentax Q place the cameras among the top in their class? Find out in the latest Best DSLR 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 technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the E-30 or the Pentax Q perform in practice. 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 hands-on reviews by experts 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.

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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
