Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon 1 J5 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 Nikon 1 J5 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 J5 can be obtained in three different colors (black, silver, 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 notably smaller (5 percent) than the Nikon 1 J5. Moreover, the Pentax Q is markedly lighter (22 percent) than the J5. In this context, it is worth noting that neither the J5 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 following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you want to switch the focus of the display and review another camera pair, you can move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

The price is, of course, an important factor in any camera decision. 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 J5 was launched at a markedly lower price (by 39 percent) than the Pentax Q, which puts it into a different market segment. 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 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. 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 Nikon 1 J5 features an one-inch sensor and the Pentax Q a 1/2.3-inch sensor. The sensor area in the Pentax Q is 76 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 5.6. The sensor in the J5 has a native 3:2 aspect ratio, while the one in the Pentax Q offers a 4:3 aspect.

With 20.7MP, the J5 offers a higher resolution than the Pentax Q (12MP), but the J5 nevertheless has larger individual pixels (pixel pitch of 2.37μm versus 1.53μm for the Pentax Q) due to its larger sensor. Moreover, the J5 is a much more recent model (by 3 years and 9 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 pixels. Coming back to sensor resolution, it should be mentioned that the J5 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Nikon 1 J5 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the J5 for good quality output (200 dots per inch) amounts to 27.8 x 18.6 inches or 70.7 x 47.1 cm, for very good quality (250 dpi) 22.3 x 14.8 inches or 56.6 x 37.7 cm, and for excellent quality (300 dpi) 18.6 x 12.4 inches or 47.1 x 31.4 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 J5 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Nikon 1 J5 has a native sensitivity range from ISO 160 to ISO 12800. The corresponding ISO settings for the Pentax Q are ISO 125 to ISO 6400 (no boost).

In terms of underlying technology, the J5 is build around a BSI-CMOS sensor, while the Pentax Q uses a CMOS imager. 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 determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). Of the two cameras under review, the J5 provides substantially higher image quality than the Pentax Q, with an overall score that is 18 points higher. This advantage is based on 0.9 bits higher color depth, 0.9 EV in additional dynamic range, and 1.3 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 also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the J5 provides a higher video resolution than the Pentax Q. It can shoot video footage at 4K/15p, while the Pentax is limited to 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The J5 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. 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 1 J5 and Pentax Q in connection with corresponding information for a sample of similar cameras.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The J5 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 reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the J5 is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).

The Nikon 1 J5 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 J5 and the Pentax Q write their files to SDXC cards. The J5 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 1 J5 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 J5 offers wifi support, while the Pentax Q does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Both the J5 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 J5 does not have a direct successor. Further information on the features and operation of the J5 and Pentax Q can be found, respectively, in the Nikon 1 J5 Manual (free pdf) or the online Pentax Q Manual.

Review summary

So how do things add up? Is the Nikon 1 J5 better than the Pentax Q or vice versa? Below is a summary of the relative strengths of each of the two contestants.

Advantages of the Nikon 1 J5:

• More detail: Offers more megapixels (20.7 vs 12MP) with a 34% higher linear resolution.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Better image quality: Scores substantially higher (18 points) in the DXO overall assessment.
• More dynamic range: Captures a larger spectrum of light and dark details (0.9 EV of extra DR).
• Better low-light sensitivity: Requires less light for good images (1.3 stops ISO advantage).
• Better video: Provides higher definition movie capture (4K/15p vs 1080/30p).
• Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
• More detailed LCD: Has a higher resolution rear screen (1037k vs 460k dots).
• More flexible LCD: Has a tilting screen for odd-angle shots in 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 (60 vs 1.5 flaps/sec) to capture the decisive moment.
• Less disturbing: Has an electronic shutter option for completely silent shooting.
• 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.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More affordable: Was introduced into a lower priced category (39 percent cheaper at launch).
• More modern: Reflects 3 years and 9 months of technical progress since the Pentax Q launch.

Reasons to prefer the Pentax Q:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• More framing options: Can be equipped with a hotshoe-mounted accessory-viewfinder.
• Less heavy: Has a lower weight (by 51g or 22 percent) and is thus easier to take along.
• Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• More heavily discounted: Has been around for much longer (launched in June 2011).

If the count of relative strengths (bullet points above) is taken as a measure, the J5 is the clear winner of the match-up (19 : 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 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 1 J5 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 J5 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 why hands-on reviews by experts are important. The adjacent summary-table relays the overall verdicts of several of the most popular 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. 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.
