Going beyond this snapshot of core features and characteristics, what are the differences between the Panasonic Lumix DMC-G2 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.
An illustration of the physical size and weight of the Panasonic G2 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 perspectives from the front, the top, and the back are available. All size dimensions are rounded to the nearest millimeter.
The G2 can be obtained in three different colors (black, blue, red), 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 (46 percent) than the Panasonic G2. Moreover, the Pentax Q is substantially lighter (58 percent) than the G2. In this context, it is worth noting that neither the G2 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.

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The G2 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Panasonic G2 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.
In terms of underlying technology, both cameras are build around CMOS sensors.
Even though the G2 has a larger sensor, both cameras offer the same resolution of 12 megapixels. This implies that the G2 has a lower pixel density and larger individual pixels (with a pixel pitch of 4.33μm versus 1.53μm for the Pentax Q), which gives it a potential advantage in terms of light gathering capacity. It should, however, be noted that the Pentax Q is a somewhat more recent model (by 1 year and 3 months) than the G2, and its sensor might have benefitted from technological advances during this time that at least partly compensate for the smaller pixel size.
The Panasonic Lumix DMC-G2 has a native sensitivity range from ISO 100 to ISO 6400. The corresponding ISO settings for the Pentax Q are ISO 125 to ISO 6400 (no boost).
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 G2 has a notably higher overall DXO score than the Pentax Q (overall score 6 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 1 bits higher color depth, 0.8 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 can also record movies. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the Pentax Q provides a better video resolution than the G2. It can shoot movie footage at 1080/30p, while the Panasonic is limited to 720/30p.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the G2 has an electronic viewfinder (1440k dots), which can be very helpful 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 Panasonic G2 and Pentax Q in connection with corresponding information for a sample of similar cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The G2 has a touchscreen, while the Pentax Q has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The G2 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.
Concerning the storage of imaging data, both the G2 and the Pentax Q write their files to 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 Panasonic Lumix DMC-G2 and Pentax Q and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the G2 and the Pentax Q have been discontinued, but can regularly be found used on eBay. The G2 was replaced by the Panasonic G3, 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 Panasonic and Pentax websites.
So how do things add up? Is there a clear favorite between the Panasonic G2 and the Pentax Q? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.
Advantages of the Panasonic Lumix DMC-G2:
- Better image quality: Scores markedly higher (6 points) in the DXO overall assessment.
- Better low-light sensitivity: Requires less light for good images (1.4 stops ISO advantage).
- Easier framing: Has an electronic viewfinder for image composition and settings control.
- More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
- Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
- Faster burst: Shoots at higher frequency (2.6 vs 1.5 flaps/sec) to capture the decisive moment.
- Longer lasting: Can take more shots (360 versus 230) on a single battery charge.
- More heavily discounted: Has been on the market for longer (launched in March 2010).
Reasons to prefer the Pentax Q:
- More dynamic range: Captures a broader range of light and dark details (0.8 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 124x84mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 248g or 58 percent) and is thus easier to take along.
- Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
- More modern: Was introduced somewhat (1 year and 3 months) more recently.
If the count of relative strengths (bullet points above) is taken as a measure, the G2 emerges as the winner of the contest (10 : 7 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.
How about other alternatives? Do the specifications of the Panasonic G2 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 technical specifications can provide a useful overview of the capabilities of different cameras, it says little about, for example, the shooting experience and imaging performance of the G2 and the Pentax Q in practical situations. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.
This is where reviews by experts come in. The following table reports the overall ratings of the cameras as published by some of the major 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.
The above review scores should be interpreted with care, 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 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.
