Body comparison

The side-by-side display below illustrates the physical size and weight of the Pentax K-1 II and the Sony NEX-C3. 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 width, height and depth measures are rounded to the nearest millimeter.

The K-1 II can be obtained in two different colors (black, silver), while the NEX-C3 is available in three color-versions (black, silver, pink).

Compare K-1 II versus NEX-C3 top
Comparison K-1 II or NEX-C3 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony NEX-C3 is considerably smaller (56 percent) than the Pentax K-1 II. Moreover, the NEX-C3 is substantially lighter (78 percent) than the K-1 II. It is worth mentioning in this context that the K-1 II is splash and dust resistant, while the NEX-C3 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 K-1 II gets 670 shots out of its Pentax D-LI90 battery, while the NEX-C3 can take 400 images on a single charge of its Sony NP-FW50 power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

Note: Measurements and pricing do not include easily detachable parts, such as add-on or 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 NEX-C3 was launched at a markedly lower price (by 70 percent) than the K-1 II, 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.

Sensor comparison

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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Pentax K-1 II features a full frame sensor and the Sony NEX-C3 an APS-C sensor. The sensor area in the NEX-C3 is 58 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Pentax K-1 II and Sony NEX-C3 sensor measures

With 36.2MP, the K-1 II offers a higher resolution than the NEX-C3 (16MP), but the K-1 II nevertheless has marginally larger individual pixels (pixel pitch of 4.88μm versus 4.78μm for the NEX-C3) due to its larger sensor. Moreover, the K-1 II is a much more recent model (by 6 years and 8 months) than the NEX-C3, 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 K-1 II has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Pentax K-1 II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the K-1 II for good quality output (200 dots per inch) amounts to 36.8 x 24.6 inches or 93.5 x 62.4 cm, for very good quality (250 dpi) 29.4 x 19.6 inches or 74.8 x 49.9 cm, and for excellent quality (300 dpi) 24.5 x 16.4 inches or 62.3 x 41.6 cm. The corresponding values for the Sony NEX-C3 are 24.6 x 16.3 inches or 62.4 x 41.5 cm for good quality, 19.6 x 13.1 inches or 49.9 x 33.2 cm for very good quality, and 16.4 x 10.9 inches or 41.6 x 27.6 cm for excellent quality prints.

Unlike the NEX-C3, the K-1 II has the capacity to capture high quality composite images by combining multiple shots after shifting its sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).

The Pentax K-1 II has a native sensitivity range from ISO 100 to ISO 819200. The corresponding ISO settings for the Sony Alpha NEX-C3 are ISO 100 to ISO 12800 (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.

K-1 II versus NEX-C3 MP

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the K-1 II has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the NEX-C3 relies on live view and the rear LCD for framing. That said, the NEX-C3 can be equipped with an optional viewfinder – the FDA-SV1. The following table reports on some other key feature differences and similarities of the Pentax K-1 II, the Sony NEX-C3, and comparable cameras.

One feature that is present on the K-1 II, but is missing on the NEX-C3 is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.

The NEX-C3 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 K-1 II does not have a selfie-screen.

The Pentax K-1 II 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 K-1 II writes its imaging data to SDXC cards, while the NEX-C3 uses SDXC or Memory Stick PRO Duo cards. The K-1 II features dual card slots, which can be very useful in case a memory card fails. In contrast, the NEX-C3 only has one slot. The K-1 II supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the NEX-C3 cannot take advantage of Ultra High Speed SD cards.

It is notable that the K-1 II has a microphone port, which is missing on the NEX-C3. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.

Studio photographers will appreciate that the Pentax K-1 II (unlike the NEX-C3) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Travel and landscape photographers will find it useful that the K-1 II has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.

The K-1 II is a recent model that features in the current product line-up of Pentax. In contrast, the NEX-C3 has been discontinued (but can be found pre-owned on ebay). There has not been a direct replacement model for the NEX-C3 from Sony. Further information on the features and operation of the K-1 II and NEX-C3 can be found, respectively, in the Pentax K-1 II Manual (free pdf) or the online Sony NEX-C3 Manual.

ilogo

Reasons to prefer the Sony Alpha NEX-C3:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Faster burst: Shoots at higher frequency (5.5 vs 4.4 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (110x60mm vs 137x110mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 785g or 78 percent) and is thus easier to take along.
  • More legacy lens friendly: Can use many non-native lenses via adapters.
  • More affordable: Was introduced into a lower priced category (70 percent cheaper at launch).
  • More heavily discounted: Has been around for much longer (launched in June 2011).

If the count of individual advantages (bullet points above) is taken as a guide, the K-1 II is the clear winner of the match-up (26 : 8 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision 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.

K-1 II 26:08 NEX-C3

How about other alternatives? Do the specifications of the Pentax K-1 II and the Sony NEX-C3 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-1 II or the NEX-C3 perform in practice. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.

Expert reviews

This is why expert reviews are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

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. 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.
