Pentax Q vs Sony NEX-5T
The Pentax Q and the Sony Alpha NEX-5T are two digital cameras that were officially introduced, respectively, in June 2011 and August 2013. Both the Pentax Q and the NEX-5T are mirrorless interchangeable lens cameras that are based on a 1/2.3-inch (Pentax Q) and an APS-C (NEX-5T) sensor. The Pentax has a resolution of 12 megapixels, whereas the Sony provides 16 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 Q and the Sony Alpha NEX-5T? 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 Pentax Q and the Sony NEX-5T is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear 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 NEX-5T is also available in two color-versions, but different ones (black, silver).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony NEX-5T is notably larger (17 percent) than the Pentax Q. Moreover, the NEX-5T is substantially heavier (53 percent) than the Pentax Q. In this context, it is worth noting that neither the Pentax Q nor the NEX-5T 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. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

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 Pentax Q was somewhat cheaper (by 7 percent) than the NEX-5T 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 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. 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 associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Pentax Q features a 1/2.3-inch sensor and the Sony NEX-5T an APS-C sensor. The sensor area in the NEX-5T is 1204 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 5.6 and 1.5. The sensor in the Pentax Q has a native 4:3 aspect ratio, while the one in the NEX-5T offers a 3:2 aspect.
With 16MP, the NEX-5T offers a higher resolution than the Pentax Q (12MP), but the NEX-5T nevertheless has larger individual pixels (pixel pitch of 4.78μm versus 1.53μm for the Pentax Q) due to its larger sensor. Moreover, the NEX-5T is a much more recent model (by 2 years and 2 months) than the Pentax Q, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.
The resolution advantage of the Sony NEX-5T implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the NEX-5T for good quality output (200 dots per inch) amounts to 24.6 x 16.3 inches or 62.4 x 41.5 cm, for very good quality (250 dpi) 19.6 x 13.1 inches or 49.9 x 33.2 cm, and for excellent quality (300 dpi) 16.4 x 10.9 inches or 41.6 x 27.6 cm. The corresponding values for the Pentax Q are 20 x 15 inches or 50.8 x 38.1 cm for good quality, 16 x 12 inches or 40.6 x 30.5 cm for very good quality, and 13.3 x 10 inches or 33.9 x 25.4 cm for excellent quality prints.
The Pentax Q has a native sensitivity range from ISO 125 to ISO 6400. The corresponding ISO settings for the Sony Alpha NEX-5T are ISO 100 to ISO 25600 (no boost).
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 consideration, the NEX-5T offers substantially better image quality than the Pentax Q (overall score 31 points higher). The advantage is based on 3.4 bits higher color depth, 1.9 EV in additional dynamic range, and 2.4 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. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the NEX-5T provides a faster frame rate than the Pentax Q. It can shoot movie footage at 1080/60p, while the Pentax is limited to 1080/30p.
Beyond body and sensor, cameras can and do differ across a range of features. The Pentax Q and the NEX-5T 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 O-VF1 for the Pentax Q and the FDA-EV1S for the NEX-5T – are available as accessories. The table below summarizes some of the other core capabilities of the Pentax Q and Sony NEX-5T in connection with corresponding information for a sample of similar cameras.
One difference between the cameras concerns the presence of an on-board flash. The Pentax Q has one, while the NEX-5T does not. While the built-in flash of the Pentax Q is not very powerful, it can at times be useful as a fill-in light.The NEX-5T has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking 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 Pentax Q writes its imaging data to SDXC cards, while the NEX-5T uses SDXC or Memory Stick PRO Duo 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 Pentax Q and Sony Alpha NEX-5T and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.
| WiFi |
It is notable that the NEX-5T offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the Pentax Q does not provide wifi capability.
Both the Pentax Q and the NEX-5T have been discontinued, but can regularly be found used on eBay. The Pentax Q was replaced by the Pentax Q10, while the NEX-5T was followed by the Sony A5100. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Pentax and Sony websites.
So what conclusions can be drawn? Is the Pentax Q better than the Sony NEX-5T or vice versa? Below is a summary of the relative strengths of each of the two contestants.
Advantages of the Pentax Q:
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- More compact: Is smaller (98x57mm vs 111x59mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 96g or 35 percent) and hence easier to carry around.
- Sharper images: Has hand-shake reducing image stabilization built-in.
- Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
- More heavily discounted: Has been available for much longer (launched in June 2011).
Reasons to prefer the Sony Alpha NEX-5T:
- More detail: Has more megapixels (16 vs 12MP), which boosts linear resolution by 18%.
- Better image quality: Scores substantially higher (31 points) in the DXO overall evaluation.
- Richer colors: Generates noticeably more natural colors (3.4 bits more color depth).
- More dynamic range: Captures a broader range of light and dark details (1.9 EV of extra DR).
- Better low-light sensitivity: Can shoot in dim conditions (2.4 stops ISO advantage).
- Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
- More detailed LCD: Has a higher resolution rear screen (922k vs 460k dots).
- More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
- Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
- 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 (10 vs 1.5 flaps/sec) to capture the decisive moment.
- Longer lasting: Gets more shots (330 versus 230) out of a single battery charge.
- Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
- Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
- More modern: Reflects 2 years and 2 months of technical progress since the Pentax Q launch.
If the count of individual advantages (bullet points above) is taken as a guide, the NEX-5T is the clear winner of the contest (16 : 6 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision. 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 Pentax Q and the Sony NEX-5T 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it says little about, for example, the shooting experience and imaging performance of the Pentax Q and the NEX-5T 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 why hands-on reviews by experts are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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.

Care should be taken when interpreting the review scores above, though. The ratings are only valid when referring to cameras in the same category and of the same age. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
