Canon 500D vs Pentax 645Z

The Canon EOS 500D (called Canon T1i in some regions) and the Pentax 645Z are two digital cameras that were announced, respectively, in March 2009 and April 2014. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (500D) and a medium format (645Z) sensor. The Canon has a resolution of 15.1 megapixels, whereas the Pentax provides 51.1 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 500D and the Pentax 645Z? 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

An illustration of the physical size and weight of the Canon 500D and the Pentax 645Z is provided in the side-by-side display below. 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.

Size Canon 500D vs Pentax 645Z
Compare 500D versus 645Z top
Comparison 500D or 645Z rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Pentax 645Z is considerably larger (44 percent) than the Canon 500D. Moreover, the 645Z is substantially heavier (198 percent) than the 500D. It is noteworthy in this context that the 645Z is splash and dust-proof, while the 500D 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 500D gets 400 shots out of its LP-E5 battery, while the 645Z can take 650 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.

Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The 500D was launched at a markedly lower price (by 91 percent) than the 645Z, 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

The size of the imaging sensor is a crucial determinant 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.

Of the two cameras under consideration, the Canon 500D features an APS-C sensor and the Pentax 645Z a medium format sensor. The sensor area in the 645Z is 333 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 500D has a native 3:2 aspect ratio, while the one in the 645Z offers a 4:3 aspect.

Canon 500D and Pentax 645Z sensor measures

With 51.1MP, the 645Z offers a higher resolution than the 500D (15.1MP), but the 645Z nevertheless has larger individual pixels (pixel pitch of 5.30μm versus 4.69μm for the 500D) due to its larger sensor. Moreover, the 645Z is a much more recent model (by 5 years) than the 500D, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the 645Z has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Pentax 645Z implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 645Z for good quality output (200 dots per inch) amounts to 41.3 x 31 inch or 104.9 x 78.6 cm, for very good quality (250 dpi) 33 x 24.8 inch or 83.9 x 62.9 cm, and for excellent quality (300 dpi) 27.5 x 20.6 inch or 69.9 x 52.4 cm. The corresponding values for the Canon 500D are 23.8 x 15.8 inch or 60.4 x 40.2 cm for good quality, 19 x 12.7 inch or 48.3 x 32.2 cm for very good quality, and 15.8 x 10.6 inch or 40.2 x 26.8 cm for excellent quality prints.

The Canon EOS 500D has a native sensitivity range from ISO 100 to ISO 6400, which can be extended to ISO 100-12800. The corresponding ISO settings for the Pentax 645Z are ISO 100 to ISO 204800 (no boost).

500D versus 645Z MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). Of the two cameras under consideration, the 645Z offers substantially better image quality than the 500D (overall score 38 points higher). The advantage is based on 4.3 bits higher color depth, 3.2 EV in additional dynamic range, and 2.8 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 645Z provides a faster frame rate than the 500D. It can shoot movie footage at 1080/60i, while the Canon is limited to 1080/20p.

 

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The 500D and the 645Z 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 645Z offers a wider field of view (98%) than the one in the 500D (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the 645Z has a higher magnification (0.78x vs 0.54x), 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 500D and Pentax 645Z 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 500D has one, while the 645Z does not. While the built-in flash of the 500D is not very powerful, it can at times be useful as a fill-in light.

The Pentax 645Z 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 500D writes its imaging data to SDHC cards, while the 645Z uses SDXC cards. The 645Z features dual card slots, which can be very useful in case a memory card fails. In contrast, the 500D only has one slot. The 645Z supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the 500D 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 500D and Pentax 645Z and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 645Z has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The 500D does not feature such a mic input.

Studio photographers will appreciate that the Pentax 645Z (unlike the 500D) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

The 645Z is a recent model that features in the current product line-up of Pentax. In contrast, the 500D has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the 500D was succeeded by the Canon 550D. 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 500D better than the Pentax 645Z or vice versa? The listing below highlights the relative strengths of the two models.

ilogo

Advantages of the Canon EOS 500D:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Faster burst: Shoots at higher frequency (3.4 vs 3 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (129x98mm vs 156x117mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 1030g or 66 percent) and hence easier to carry around.
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
  • More affordable: Was introduced into a lower priced category (91 percent cheaper at launch).
  • More heavily discounted: Has been available for much longer (launched in March 2009).

ilogo

Reasons to prefer the Pentax 645Z:

  • More detail: Has more megapixels (51.1 vs 15.1MP), which boosts linear resolution by 81%.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Better image quality: Scores substantially higher (38 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (4.3 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (3.2 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (2.8 stops ISO advantage).
  • Better video: Provides higher movie framerates (1080/60i versus 1080/20p).
  • Better sound: Can connect to an external microphone for higher quality sound recording.
  • 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 0.54x).
  • Easier setting verification: Features a control panel on top to check shooting parameters.
  • Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (1037k vs 920k dots).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • Longer lasting: Gets more shots (650 versus 400) out of a single battery charge.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • Faster data transfer: Supports a more advanced USB protocol (3.0 vs 2.0).
  • 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.
  • Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
  • More modern: Reflects 5 years of technical progress since the 500D launch.

If the number of relative strengths (bullet points above) is taken as a guide, the 645Z is the clear winner of the contest (22 : 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. 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.

500D 07:22 645Z

How about other alternatives? Do the specifications of the Canon 500D and the Pentax 645Z 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 500D or the 645Z 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.

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 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
