Canon 5DS versus Pentax K-1

The Canon EOS 5DS and the Pentax K-1 are two digital cameras that were announced, respectively, in February 2015 and February 2016. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with a full frame sensor. The Canon has a resolution of 50.3 megapixel, whereas the Pentax provides 36.2 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Canon 5DS vs Pentax K-1

The physical size and weight of the Canon 5DS and the Pentax K-1 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 dimensions are rounded to the nearest millimeter. You can also toggle the display to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left – the 5DS – represents the basis or 100 percent across all the size and weight measures).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Pentax K-1 is notably smaller (15 percent) than the Canon 5DS. However, the K-1 is markedly heavier (9 percent) than the 5DS. 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 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 5DS gets 700 shots out of its LP-E6 battery, while the K-1 can take 760 images on a single charge of its D-LI90 power pack.

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, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

The camera’s price is obviously a critical decision-making factor. 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 K-1 was launched at a markedly lower price (by 51 percent) than the 5DS, 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: Canon 5DS vs Pentax K-1

The size of the sensor inside a digital camera is one of the key determinants of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have 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 associated with larger, more expensive camera bodies and lenses.

Both cameras under consideration feature a full frame sensor, but their sensors differ slightly in size. They nevertheless have the same format factor of 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Canon 5DS and Pentax K-1 sensor measures

With 50.3MP, the 5DS offers a higher resolution than the K-1 (36.2MP), but the 5DS has smaller individual pixels (pixel pitch of 4.14μm versus 4.88μm for the K-1). Moreover, the K-1 is a somewhat more recent model (by 1 year) than the 5DS, and its sensor might 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 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

Unlike the 5DS, the K-1 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).

5DS versus K-1 MP

For many cameras, data on sensor performance has been reported by DXO Mark. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. Of the two cameras under consideration, the K-1 has a markedly higher DXO score than the 5DS (overall score 9 points higher), which will translate into better image quality. The advantage is based on 0.7 bits higher color depth, 2.2 EV in additional dynamic range, and 0.5 stops in additional low light sensitivity. 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 are not only capable of taking still images, but can also record movies. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the 5DS provides a higher frame rate than the K-1. It can shoot video footage at 1080/60p, while the Pentax is limited to 1080/60i.

 

Feature comparison: Canon 5DS vs Pentax K-1

Beyond body and sensor, cameras can and do differ across a range of features. The 5DS and the K-1 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 following table reports on some other key feature differences and similarities of the Canon 5DS, the Pentax K-1, and comparable cameras. If you need more detail on the specs, you can find comprehensive listings, for example, in the dpreview camera hub.

One feature that differentiates the K-1 and the 5DS is in-body image stabilization (IBIS). The K-1 reduces the risk of handshake-induced blur with all attached lenses, while the 5DS has to rely on optical image stabilization in OIS-equipped lenses to achieve the same effect.

The 5DS writes its imaging data to Compact Flash or SDXC cards, while the K-1 uses SDXC cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails.

The 5DS is a current model that online retailers, such as amazon, will have in stock. In contrast, the K-1 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the K-1 was succeeded by the Pentax K-1 II.

Review summary: Canon 5DS vs Pentax K-1

So what conclusions can be drawn? Which of the two cameras – the Canon 5DS or the Pentax K-1 – has the upper hand? A synthesis of the relative strong points of each of the models is listed below.

ilogo

Arguments in favor of the Canon EOS 5DS:

  • More detail: Offers more megapixels (50.3 vs 36.2MP) with a 18% higher linear resolution.
  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Better video: Provides higher movie framerates (1080/60p versus 1080/60i).
  • Faster burst: Shoots at higher frequency (5 vs 4.4 flaps/sec) to capture the decisive moment.
  • Faster data transfer: Supports a more advanced USB protocol (3.0 vs 2.0).
  • More heavily discounted: Has been on the market for longer (launched in February 2015).

ilogo

Reasons to prefer the Pentax K-1:

  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • High quality composites: Can combine several shots after pixel-shifting its sensor.
  • Better image quality: Scores markedly higher (9 points) in the DXO overall evaluation.
  • More dynamic range: Captures a broader range of light and dark details (2.2 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (0.5 stops ISO advantage).
  • Better sound control: Has a headphone port that enables audio monitoring while recording.
  • More flexible LCD: Has full-flex screen for odd-angle shots in portrait or landscape orientation.
  • More compact: Is smaller (137x110mm vs 152x116mm) and will fit more readily into a bag.
  • Sharper images: Has stabilization technology build-in to reduce the impact of hand-shake.
  • Easier file upload: Has wifi build in for automatic backup or image transfer to the web.
  • More affordable: Was introduced into a lower priced category (51 percent cheaper at launch).
  • More modern: Was introduced somewhat (1 year) more recently.

If the number of relative strengths (bullet points above) is taken as a guide, the K-1 is the clear winner of the contest (12 : 6 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.

5DS 06:12 K-1

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the 5DS and the K-1 in practical situations. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased. This is why expert reviews are important. The table below summarizes the assessments of some of the best known camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The review scores listed above should be treated with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
