Body comparison

The physical size and weight of the Nikon D3400 and the Pentax K-S2 are illustrated 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 size dimensions are rounded to the nearest millimeter.

The D3400 can be obtained in two different colors (black, red), while the K-S2 is available in six color-versions (black, grey, pink, orange, green, white).

Compare D3400 versus K-S2 top
Comparison D3400 or K-S2 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Pentax K-S2 is notably smaller (8 percent) than the Nikon D3400. However, the K-S2 is substantially heavier (52 percent) than the D3400. It is noteworthy in this context that the K-S2 is splash and dust-proof, while the D3400 does not feature any corresponding weather-sealing.

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.

Concerning battery life, the D3400 gets 1200 shots out of its Nikon EN-EL14a battery, while the K-S2 can take 410 images on a single charge of its Pentax D-LI109 power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The D3400 was launched at a markedly lower price (by 33 percent) than the K-S2, 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. 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. 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.

Both cameras under consideration feature an APS-C sensor and have a format factor (sometimes also referred to as "crop factor") of 1.5. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Nikon D3400 and Pentax K-S2 sensor measures

While the two cameras under review share the same sensor size, the D3400 offers a higher resolution of 24 megapixels, compared with 20 MP of the K-S2. This megapixels advantage translates into a 10 percent gain in linear resolution. On the other hand, these sensor specs imply that the D3400 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.91μm versus 4.28μm for the K-S2). In this context, it should be noted, however, that the D3400 is a somewhat more recent model (by 1 year and 6 months) than the K-S2, and its sensor might have benefitted from technological advances during this time that at least partly compensate for the smaller pixel size. Coming back to sensor resolution, it should be mentioned that neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.

The resolution advantage of the Nikon D3400 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D3400 for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the Pentax K-S2 are 27.4 x 18.2 inches or 69.5 x 46.3 cm for good quality, 21.9 x 14.6 inches or 55.6 x 37.1 cm for very good quality, and 18.2 x 12.2 inches or 46.3 x 30.9 cm for excellent quality prints.

The Nikon D3400 has a native sensitivity range from ISO 100 to ISO 25600. The corresponding ISO settings for the Pentax K-S2 are ISO 100 to ISO 51200 (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.

D3400 versus K-S2 MP

For many cameras, data on sensor performance has been reported by DXO Mark. 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"). 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 cannot only take still pictures, but also record videos. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the D3400 provides a higher frame rate than the K-S2. It can shoot video footage at 1080/60p, 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 D3400 and the K-S2 are similar in the sense that both have an optical viewfinder. The latter is useful for getting a clear image for framing even in brightly lit environments. The viewfinder in the K-S2 offers a wider field of view (100%) than the one in the D3400 (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the K-S2 has a higher magnification (0.63x vs 0.57x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Nikon D3400 and Pentax K-S2 in connection with corresponding information for a sample of similar cameras.

One feature that differentiates the K-S2 and the D3400 is in-body image stabilization (IBIS). The K-S2 reduces the risk of handshake-induced blur with all attached lenses, while the D3400 offers no blur reduction with lenses that themselves do not provide optical image stabilization.

The K-S2 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 D3400 does not have a selfie-screen.

The Pentax K-S2 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 D3400 and the K-S2 write their files to SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.

It is notable that the K-S2 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the D3400 does not provide wifi capability.

Both the D3400 and the K-S2 have been discontinued, but can regularly be found used on ebay. The D3400 was replaced by the Nikon D3500, while the K-S2 does not have a direct successor. Further information on the features and operation of the D3400 and K-S2 can be found, respectively, in the Nikon D3400 Manual (free pdf) or the online Pentax K-S2 Manual.

Review summary

So how do things add up? Is the Nikon D3400 better than the Pentax K-S2 or vice versa? A synthesis of the relative strong points of each of the models is listed below.

ilogo

Reasons to prefer the Nikon D3400:

  • More detail: Offers more megapixels (24 vs 20MP) with a 10% higher linear resolution.
  • Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
  • Less heavy: Is lighter (by 233g or 34 percent) and hence easier to carry around.
  • Longer lasting: Can take more shots (1200 versus 410) on a single battery charge.
  • Easier wireless transfer: Supports Bluetooth for image sharing without cables.
  • More affordable: Was introduced into a lower priced category (33 percent cheaper at launch).
  • More modern: Is somewhat more recent (announced 1 year and 6 months after the K-S2).

ilogo

Advantages of the Pentax K-S2:

  • Better sound: Can connect to an external microphone for higher quality sound recording.
  • More complete view: Has a viewfinder with a larger field of view (100% vs 95%).
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.63x vs 0.57x).
  • 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 (1/6000s vs 1/4000s) to freeze action.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
  • 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 heavily discounted: Has been on the market for longer (launched in February 2015).

If the number of relative strengths (bullet points above) is taken as a guide, the K-S2 is the clear winner of the contest (12 : 7 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.

D3400 07:12 K-S2

How about other alternatives? Do the specifications of the Nikon D3400 and the Pentax K-S2 place the cameras among the top in their class? Find out in the latest Best DSLR 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 incomplete and does no justice, for example, to the way the D3400 or the K-S2 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 expert reviews 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.

Care should be taken when interpreting the review scores above, though. The assessments were made in relation to similar cameras of the same technological generation. A score, therefore, has to be seen in close connection to the price and market introduction time 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.
