Going beyond this snapshot of core features and characteristics, what are the differences between the Pentax K-3 and the Samsung NX1? 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: Pentax K-3 vs Samsung NX1

The physical size and weight of the Pentax K-3 and the Samsung NX1 are illustrated 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 width, height and depth measures are rounded to the nearest millimeter.

The K-3 can be obtained in two different colors (black, silver), while the NX1 is only available in black.

Compare K-3 versus NX1 top
Comparison K-3 or NX1 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Samsung NX1 is notably larger (8 percent) than the Pentax K-3. However, the NX1 is markedly lighter (31 percent) than the K-3. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.

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 power pack in the NX1 can be charged via the USB port, which can be very convenient when travelling.

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

Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.

The price is, of course, an important factor in any camera decision. 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 K-3 was launched at a somewhat lower price (by 13 percent) than the NX1, 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: Pentax K-3 vs Samsung NX1

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. 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 more expensive and lead to bigger and heavier cameras and lenses.

Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the NX1 is 1 percent bigger. They nevertheless have the same format factor of 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Pentax K-3 and Samsung NX1 sensor measures

With 28MP, the NX1 offers a higher resolution than the K-3 (24.1MP), but the NX1 has smaller individual pixels (pixel pitch of 3.63μm versus 3.90μm for the K-3). Yet, the NX1 is a somewhat more recent model (by 11 months) than the K-3, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units. 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 Samsung NX1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the NX1 for good quality output (200 dots per inch) amounts to 32.4 x 21.6 inch or 82.3 x 54.9 cm, for very good quality (250 dpi) 25.9 x 17.3 inch or 65.8 x 43.9 cm, and for excellent quality (300 dpi) 21.6 x 14.4 inch or 54.9 x 36.6 cm. The corresponding values for the Pentax K-3 are 30.1 x 20 inch or 76.4 x 50.8 cm for good quality, 24.1 x 16 inch or 61.1 x 40.6 cm for very good quality, and 20.1 x 13.3 inch or 50.9 x 33.9 cm for excellent quality prints.

The NX1 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Pentax K-3 has a native sensitivity range from ISO 100 to ISO 51200. The corresponding ISO settings for the Samsung NX1 are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 100-51200.

K-3 versus NX1 MP

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"). The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the NX1 provides a better video resolution than the K-3. It can shoot movie footage at 4K/30p, while the Pentax is limited to 1080/60i.

 

Feature comparison: Pentax K-3 vs Samsung NX1

Beyond body and sensor, cameras can and do differ across a range of features. For example, the NX1 has an electronic viewfinder (2360k dots), while the K-3 has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The viewfinders of both cameras offer the same field of view (100%), but the viewfinder of the NX1 has a higher magnification than the one of the K-3 (0.69x vs 0.63x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The following table reports on some other key feature differences and similarities of the Pentax K-3, the Samsung NX1, and comparable cameras.

One feature that differentiates the K-3 and the NX1 is in-body image stabilization (IBIS). The K-3 reduces the risk of handshake-induced blur with all attached lenses, while the NX1 has to rely on optical image stabilization in OIS-equipped lenses to achieve the same effect.

The Pentax K-3 and the Samsung NX1 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 K-3 and the NX1 write their files to SDXC cards. The K-3 features dual card slots, which can be very useful in case a memory card fails. In contrast, the NX1 only has one slot. The NX1 supports UHS-II cards (on its first slot), while the K-3 can use UHS-I cards.

 

Connectivity comparison: Pentax K-3 vs Samsung NX1

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 K-3 and Samsung NX1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the NX1 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the K-3 does not offer wifi capability.

Studio photographers will appreciate that the Pentax K-3 (unlike the NX1) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the K-3 and the NX1 have been discontinued, but can regularly be found used on eBay. The K-3 was replaced by the Pentax K-3 II, while the NX1 does not have a direct successor. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Pentax and Samsung websites.


Review summary: Pentax K-3 vs Samsung NX1

So what conclusions can be drawn? Is there a clear favorite between the Pentax K-3 and the Samsung NX1? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

ilogo

  • More heavily discounted: Has been on the market for longer (launched in October 2013).

ilogo

Arguments in favor of the Samsung NX1:

  • More detail: Has more megapixels (28 vs 24.1MP), which boosts linear resolution by 8%.
  • Better video: Provides higher definition movie capture (4K/30p vs 1080/60i).
  • Better live-view autofocus: Features on-sensor phase-detection for quicker and more confident autofocus.
  • More framing info: Has an electronic viewfinder that displays shooting data.
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.69x vs 0.63x).
  • 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.
  • Faster burst: Shoots at higher frequency (15 vs 8.3 flaps/sec) to capture the decisive moment.
  • Less heavy: Has a lower weight (by 250g or 31 percent) and is thus easier to take along.
  • Easier travel charging: Can be conveniently charged via its USB port.
  • More legacy lens friendly: Can use many non-native lenses via adapters.
  • 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.
  • Easier wireless transfer: Supports Bluetooth for image sharing without cables.
  • Faster buffer clearing: Supports a more advanced SD data transfer standard (UHS-II vs UHS-I).
  • More modern: Was introduced somewhat (11 months) more recently.

If the count of relative strengths (bullet points above) is taken as a measure, the NX1 is the clear winner of the contest (15 : 8 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 Pentax K-3 and the Samsung NX1 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 technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the K-3 or the NX1 perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews: Pentax K-3 vs Samsung NX1

This is why hands-on reviews by experts are important. 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 review scores listed above should be treated with care, 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 comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
