Canon 200D versus Pentax 645D

The Canon EOS 200D (called Canon SL2 in some regions) and the Pentax 645D are two digital cameras that were revealed to the public, respectively, in June 2017 and March 2010. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (200D) and a medium format (645D) sensor. The Canon has a resolution of 24 megapixel, whereas the Pentax provides 39.5 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 200D vs Pentax 645D

An illustration of the physical size and weight of the Canon 200D and the Pentax 645D is provided 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 size dimensions are rounded to the nearest millimeter. If you prefer, you can also use the toggle button to switch to a comparison in percentage terms (in this case, the camera on the left – the 200D – 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 Pentax 645D is considerably larger (61 percent) than the Canon 200D. Moreover, the 645D is substantially heavier (227 percent) than the 200D. It is noteworthy in this context that the 645D is splash and dust-proof, while the 200D 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 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 200D gets 650 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 adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. If you would like to visualize and compare a different camera combination, just use the right or left arrows in the table to switch to the respective camera.

Any camera purchase will naturally be influenced heavily by the price. 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 200D was launched at a markedly lower price (by 95 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

 

Sensor comparison: Canon 200D vs Pentax 645D

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

Of the two cameras under consideration, the Canon 200D 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 200D has a native 3:2 aspect ratio, while the one in the 645D offers a 4:3 aspect.

Canon 200D and Pentax 645D sensor measures

With 39.5MP, the 645D offers a higher resolution than the 200D (24MP), but the 645D nevertheless has larger individual pixels (pixel pitch of 6.06μm versus 3.72μm for the 200D) due to its larger sensor. However, the 200D is a much more recent model (by 7 years and 3 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 200D has on-sensor phase detect pixels, which results in relatively fast and reliable autofocus acquisition during video recording.

200D 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. The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar image quality. 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 also of capturing video footage. The 200D indeed provides movie recording capabilities, while the 645D does not. The highest resolution format that the 200D can use is 1080/60p.

 

Feature comparison: Canon 200D vs Pentax 645D

Apart from body and sensor, cameras can and do differ across a range of features. The 200D 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 adjacent table lists some of the other core features of the Canon 200D and Pentax 645D along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The 200D has one, while the 645D does not. While the build-in flash of the 200D is not very powerful, it can at times be useful as a fill-in light.

Both the 200D and the 645D write their imaging data to SDXC cards. The 645D features dual card slots, which can be very useful in case a memory card fails. In contrast, the 200D only has one slot.

The 200D is a recent model that features in the current product line-up of Canon. In contrast, the 645D has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the 645D was succeeded by the Pentax 645Z.

Review summary: Canon 200D vs Pentax 645D

So how do things add up? Which of the two cameras – the Canon 200D or the Pentax 645D – has the upper hand? The listing below highlights the relative strengths of the two models.

ilogo

Advantages of the Canon EOS 200D:

  • 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 (0.8 EV of extra DR).
  • Broader imaging potential: Can record not only still images but also 1080/60p movies.
  • Better video autofocus: Features on-sensor phase-detection for more confident movie autofocus.
  • 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: Is equipped with a touch-sensitive rear screen to facilitate handling.
  • Faster burst: Shoots at higher frequency (5 vs 1.1 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (122x93mm vs 156x117mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 1027g or 69 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 build 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.
  • More affordable: Was introduced into a lower priced category (95 percent cheaper at launch).
  • More modern: Reflects 7 years and 3 months of technical progress since the 645D launch.

ilogo

Arguments in favor of 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.
  • Easier setting verification: Features a control panel on top to check shooting parameters.
  • Longer lasting: Gets more shots (800 versus 650) out of a single battery charge.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • 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 count of relative strengths (bullet points above) is taken as a measure, the 200D is the clear winner of the match-up (16 : 7 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.

200D 16:07 645D

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 200D or the 645D handle or perform in practice. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate. This is why expert reviews are important. The adjacent table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

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. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
