Nikon D5100 vs Pentax Q
The Nikon D5100 and the Pentax Q are two digital cameras that were announced, respectively, in April 2011 and June 2011. The D5100 is a DSLR, while the Pentax Q is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (D5100) and a 1/2.3-inch (Pentax Q) sensor. The Nikon has a resolution of 16.1 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 Nikon D5100 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 Nikon D5100 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 Pentax Q can be obtained in two different colors (black, white), while the D5100 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 (55 percent) than the Nikon D5100. Moreover, the Pentax Q is substantially lighter (68 percent) than the D5100. In this context, it is worth noting that neither the D5100 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 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 Pentax Q was launched at a somewhat lower price (by 13 percent) than the D5100, which makes it more attractive for photographers on a tight budget. 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.
Sensor comparison
The size of the imaging sensor is a crucial determinant 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 associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Nikon D5100 features an APS-C sensor and the Pentax Q a 1/2.3-inch sensor. The sensor area in the Pentax Q is 92 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 5.6. The sensor in the D5100 has a native 3:2 aspect ratio, while the one in the Pentax Q offers a 4:3 aspect.
With 16.1MP, the D5100 offers a higher resolution than the Pentax Q (12MP), but the D5100 nevertheless has larger individual pixels (pixel pitch of 4.80μm versus 1.53μm for the Pentax Q) due to its larger sensor. It is noteworthy in this context that the two cameras were released in close succession, so that their sensors are from the same technological generation.
The resolution advantage of the Nikon D5100 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D5100 for good quality output (200 dots per inch) amounts to 24.6 x 16.3 inches or 62.6 x 41.5 cm, for very good quality (250 dpi) 19.7 x 13.1 inches or 50.1 x 33.2 cm, and for excellent quality (300 dpi) 16.4 x 10.9 inches or 41.7 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 Nikon D5100 has a native sensitivity range from ISO 100 to ISO 6400, which can be extended to ISO 100-25600. 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 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 D5100 provides substantially higher image quality than the Pentax Q, with an overall score that is 33 points higher. This advantage is based on 3.3 bits higher color depth, 2.5 EV in additional dynamic range, and 2.6 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 also of capturing video footage. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, and both provide the same movie specifications (1080/30p).
Feature comparison
Beyond body and sensor, cameras can and do differ across a range of features. For example, the D5100 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 Nikon D5100 and Pentax Q in connection with corresponding information for a sample of similar cameras.

One feature that differentiates the Pentax Q and the D5100 is in-body image stabilization (IBIS). The Pentax Q reduces the risk of handshake-induced blur with all attached lenses, while the D5100 offers no blur reduction with lenses that themselves do not provide optical image stabilization.
The D5100 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 Nikon D5100 and the Pentax Q both have 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 D5100 and the Pentax Q write their files to SDXC cards. The D5100 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the Pentax Q cannot take advantage of Ultra High Speed SD cards.
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 Nikon D5100 and Pentax Q and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the D5100 has a microphone port, which is missing on the Pentax Q. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.
Both the D5100 and the Pentax Q have been discontinued, but can regularly be found used on ebay. The D5100 was replaced by the Nikon D5200, while the Pentax Q was followed by the Pentax Q10. Further information on the features and operation of the D5100 and Pentax Q can be found, respectively, in the Nikon D5100 Manual (free pdf) or the online Pentax Q Manual.
Review summary
So what conclusions can be drawn? Which of the two cameras – the Nikon D5100 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.
Reasons to prefer the Nikon D5100:
- More detail: Offers more megapixels (16.1 vs 12MP) with a 18% higher linear resolution.
- Better image quality: Scores substantially higher (33 points) in the DXO overall assessment.
- Richer colors: Generates images with noticeably better colors (3.3 bits more color depth).
- More dynamic range: Captures a larger spectrum of light and dark details (2.5 EV of extra DR).
- Better low-light sensitivity: Requires less light for good images (2.6 stops ISO advantage).
- Better sound: Can connect to an external microphone for higher quality sound recording.
- Easier framing: Has an optical viewfinder for image composition and settings control.
- More detailed LCD: Has a higher resolution rear screen (921k vs 460k dots).
- 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 (1/4000s vs 1/2000s) to freeze action.
- Faster burst: Shoots at higher frequency (4 vs 1.5 flaps/sec) to capture the decisive moment.
- Longer lasting: Can take more shots (660 versus 230) on a single battery charge.
- Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
Advantages of the Pentax Q:
- More compact: Is smaller (98x57mm vs 128x97mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 380g or 68 percent) and is thus easier to take along.
- Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
- More legacy lens friendly: Can use many non-native lenses via adapters.
- More affordable: Was released into a lower priced segment (13 percent cheaper at launch).
If the count of individual advantages (bullet points above) is taken as a guide, the D5100 is the clear winner of the match-up (14 : 5 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 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 Nikon D5100 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 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 D5100 or the Pentax Q. 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 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 (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 ratings are only valid when referring to cameras in the same category and of the same age. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
