Canon 77D vs Pentax 645D

The Canon EOS 77D and the Pentax 645D are two digital cameras that were officially introduced, respectively, in February 2017 and March 2010. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (77D) and a medium format (645D) sensor. The Canon has a resolution of 24 megapixels, whereas the Pentax provides 39.5 MP.

Below is an overview of the main specs of the two cameras as a starting point for the comparison.

Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS 77D and the Pentax 645D? 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

The side-by-side display below illustrates the physical size and weight of the Canon 77D and the Pentax 645D. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter.

Size Canon 77D vs Pentax 645D
Compare 77D versus 645D top
Comparison 77D or 645D rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Pentax 645D is notably larger (39 percent) than the Canon 77D. Moreover, the 645D is substantially heavier (174 percent) than the 77D. It is noteworthy in this context that the 645D is splash and dust-proof, while the 77D 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 77D gets 600 shots out of its LP-E17 battery, while the 645D can take 800 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.

(1) Number of images that can be taken on a full battery charge according to the CIPA-standard; (2) Official announcement.

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 77D was launched at a markedly lower price (by 91 percent) than the 645D, 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon 77D features an APS-C sensor and the Pentax 645D a medium format sensor. The sensor area in the 645D is 337 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 0.79. The sensor in the 77D has a native 3:2 aspect ratio, while the one in the 645D offers a 4:3 aspect.

Canon 77D and Pentax 645D sensor measures

With 39.5MP, the 645D offers a higher resolution than the 77D (24MP), but the 645D nevertheless has larger individual pixels (pixel pitch of 6.06μm versus 3.72μm for the 77D) due to its larger sensor. However, the 77D is a much more recent model (by 6 years and 11 months) than the 645D, and its sensor will 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 the 645D has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Pentax 645D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 645D for good quality output (200 dots per inch) amounts to 36.3 x 27.2 inches or 92.3 x 69.1 cm, for very good quality (250 dpi) 29.1 x 21.8 inches or 73.8 x 55.3 cm, and for excellent quality (300 dpi) 24.2 x 18.1 inches or 61.5 x 46.1 cm. The corresponding values for the Canon 77D are 30 x 20 inches or 76.2 x 50.8 cm for good quality, 24 x 16 inches or 61 x 40.6 cm for very good quality, and 20 x 13.3 inches or 50.8 x 33.9 cm for excellent quality prints.

The 77D has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Canon EOS 77D has a native sensitivity range from ISO 100 to ISO 25600, which can be extended to ISO 100-51200. The corresponding ISO settings for the Pentax 645D are ISO 100 to ISO 1600 (no boost).

77D versus 645D 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 645D has a markedly higher DXO score than the 77D (overall score 4 points higher), which will translate into better image quality. The advantage is based on 1 bits higher color depth, 0.7 EV of lower dynamic range, and 0.4 stops in additional low light sensitivity. 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 cannot only take still pictures, but also record videos. The 77D indeed provides movie recording capabilities, while the 645D does not. The highest resolution format that the 77D can use is 1080/60p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The 77D and the 645D 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 645D offers a wider field of view (98%) than the one in the 77D (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the 645D has a higher magnification (0.78x vs 0.51x), 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 Canon 77D and Pentax 645D in connection with corresponding information for a sample of similar cameras.

One difference between the cameras concerns the presence of an on-board flash. The 77D has one, while the 645D does not. While the built-in flash of the 77D is not very powerful, it can at times be useful as a fill-in light.

The 77D has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the 645D does not have a selfie-screen.

The Canon 77D and the Pentax 645D 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 77D and the 645D write their files to SDXC cards. The 645D features dual card slots, which can be very useful in case a memory card fails. In contrast, the 77D only has one slot. The 77D supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the 645D cannot take advantage of Ultra High Speed SD cards.

Connectivity comparison

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 Canon EOS 77D and Pentax 645D and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 77D offers wifi support, while the 645D does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Studio photographers will appreciate that the Pentax 645D (unlike the 77D) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

The 77D is a recent model that features in the current product line-up of Canon. In contrast, the 645D has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the 645D was succeeded by the Pentax 645Z. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Pentax websites.

Review summary

So what conclusions can be drawn? Is the Canon 77D better than the Pentax 645D or vice versa? The listing below highlights the relative strengths of the two models.

ilogo

Advantages of the Canon EOS 77D:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • More dynamic range: Captures a larger spectrum of light and dark details (0.7 EV of extra DR).
  • Broader imaging potential: Can record not only still images but also 1080/60p movies.
  • Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 921k dots).
  • More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
  • Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Faster burst: Shoots at higher frequency (6 vs 1.1 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (131x100mm vs 156x117mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 940g or 64 percent) and hence easier to carry around.
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
  • 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 affordable: Was introduced into a lower priced category (91 percent cheaper at launch).
  • More modern: Reflects 6 years and 11 months of technical progress since the 645D launch.

ilogo

Reasons to prefer the Pentax 645D:

  • More detail: Has more megapixels (39.5 vs 24MP), which boosts linear resolution by 26%.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Better image quality: Scores markedly higher (4 points) in the DXO overall evaluation.
  • Better low-light sensitivity: Can shoot in dim conditions (0.4 stops ISO advantage).
  • More complete view: Has a viewfinder with a larger field of view (98% vs 95%).
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.78x vs 0.51x).
  • Longer lasting: Gets more shots (800 versus 600) out of a single battery charge.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
  • More heavily discounted: Has been around for much longer (launched in March 2010).

If the number of relative strengths (bullet points above) is taken as a guide, the 77D is the clear winner of the match-up (18 : 11 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.

77D 18:11 645D

How about other alternatives? Do the specifications of the Canon 77D and the Pentax 645D 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 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 77D or the 645D 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

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.

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

The above review scores should be interpreted with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. 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.
