Pentax K-5 versus Canon 80D

The Pentax K-5 and the Canon EOS 80D are two enthusiast cameras that were officially introduced, respectively, in September 2010 and February 2016. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The Pentax has a resolution of 16.1 megapixel, whereas the Canon provides 24 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: Pentax K-5 vs Canon 80D

The side-by-side display below illustrates the physical size and weight of the Pentax K-5 and the Canon 80D. 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 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 K-5 – represents 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 Canon 80D is notably larger (15 percent) than the Pentax K-5. However, the 80D is slightly lighter (4 percent) than the K-5. 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 K-5 gets 740 shots out of its D-LI90 battery, while the 80D can take 960 images on a single charge of its LP-E6N 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 listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The K-5 was somewhat cheaper (by 8 percent) than the 80D at launch, but both cameras fall into the same price category. 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-5 vs Canon 80D

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. 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 80D is 9 percent smaller. As a result of these sensor size differences, the cameras have format factors, respectively, of 1.5 (K-5) and 1.6. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.

Pentax K-5 and Canon 80D sensor measures

Despite having a smaller sensor, the 80D offers a higher resolution of 24 megapixel, compared with 16.1 MP of the K-5. This megapixel advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.75μm versus 4.81μm for the K-5). However, it should be noted that the 80D is much more recent (by 5 years and 4 months) than the K-5, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

K-5 versus 80D MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar image quality. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the 80D provides a faster frame rate than the K-5. It can shoot movie footage at 1080/60p, while the Pentax is limited to 1080/25p.

 

Feature comparison: Pentax K-5 vs Canon 80D

Apart from body and sensor, cameras can and do differ across a variety of features. The K-5 and the 80D 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 Pentax K-5, the Canon 80D, and comparable cameras.

One feature that differentiates the K-5 and the 80D is in-body image stabilization (IBIS). The K-5 reduces the risk of handshake-induced blur with all attached lenses, while the 80D has to rely on optical image stabilization in OIS-equipped lenses to achieve the same effect.

Both the K-5 and the 80D write their imaging data to SDXC cards.

The 80D is a current model that online retailers, such as amazon, will have in stock. In contrast, the K-5 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the K-5 was succeeded by the Pentax K-5 II.

Review summary: Pentax K-5 vs Canon 80D

So what conclusions can be drawn? Which of the two cameras – the Pentax K-5 or the Canon 80D – has the upper hand? The listing below highlights the relative strengths of the two models.

ilogo

Reasons to prefer the Pentax K-5:

  • More dynamic range: Captures a larger spectrum of light and dark details (0.9 EV of extra DR).
  • More compact: Is smaller (131x97mm vs 139x105mm) and thus needs less room in the bag.
  • Sharper images: Has hand-shake reducing image stabilization build-in.
  • More heavily discounted: Has been available for much longer (launched in September 2010).

ilogo

Arguments in favor of the Canon EOS 80D:

  • More detail: Has more megapixels (24 vs 16.1MP), which boosts linear resolution by 22%.
  • Better video: Provides higher movie framerates (1080/60p versus 1080/25p).
  • Better sound control: Has a headphone port that enables audio monitoring while recording.
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 921k dots).
  • More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • Longer lasting: Gets more shots (960 versus 740) out of a single battery charge.
  • Easier file upload: Has wifi build in for automatic backup or image transfer to the web.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • More modern: Reflects 5 years and 4 months of technical progress since the K-5 launch.

If the count of individual advantages (bullet points above) is taken as a guide, the 80D is the clear winner of the contest (10 : 4 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.

K-5 04:10 80D

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 K-5 and the 80D 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 where reviews by experts come in. The following table reports the overall rankings of the cameras as published by some of the major 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. 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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
