Canon 20D vs Ricoh GR

The Canon EOS 20D and the Ricoh GR are two digital cameras that were officially introduced, respectively, in August 2004 and April 2013. The 20D is a DSLR, while the GR is a fixed lens compact. Both cameras are equipped with an APS-C sensor. The Canon has a resolution of 8.2 megapixels, whereas the Ricoh provides 16.1 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 20D and the Ricoh GR? 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 20D and the Ricoh GR 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.

Compare 20D versus GR top
Comparison 20D or GR rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Ricoh GR is considerably smaller (53 percent) than the Canon 20D. In this context, it is worth noting that neither the 20D nor the GR are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the GR has a lens built in, whereas the 20D is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the 20D and their specifications in the Canon EF Lens Catalog.

Concerning battery life, the 20D gets 700 shots out of its BP-511A battery, while the GR can take 290 images on a single charge of its DB65 power pack. The power pack in the GR can be charged via the USB port, which can be very convenient when travelling.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. 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.

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

Any camera decision will obviously take relative prices into account. 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 GR was launched at a lower price than the 20D, despite having a lens built in. 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

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. 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 GR is 9 percent bigger. As a result of these sensor size differences, the cameras have format factors, respectively, of 1.6 (20D) and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

In terms of underlying technology, both cameras are build around CMOS sensors.

Canon 20D and Ricoh GR sensor measures

With 16.1MP, the GR offers a higher resolution than the 20D (8.2MP), but the GR has smaller individual pixels (pixel pitch of 4.79μm versus 6.42μm for the 20D). Yet, the GR is a much more recent model (by 8 years and 7 months) than the 20D, 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 GR has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Ricoh GR implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GR for good quality output (200 dots per inch) amounts to 24.6 x 16.3 inch or 62.6 x 41.5 cm, for very good quality (250 dpi) 19.7 x 13.1 inch or 50.1 x 33.2 cm, and for excellent quality (300 dpi) 16.4 x 10.9 inch or 41.7 x 27.6 cm. The corresponding values for the Canon 20D are 17.5 x 11.7 inch or 44.5 x 29.7 cm for good quality, 14 x 9.3 inch or 35.6 x 23.7 cm for very good quality, and 11.7 x 7.8 inch or 29.7 x 19.8 cm for excellent quality prints.

The Canon EOS 20D has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 100-3200. The corresponding ISO settings for the Ricoh GR are ISO 100 to ISO 25600 (no boost).

20D versus GR MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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"). Of the two cameras under consideration, the GR offers substantially better image quality than the 20D (overall score 16 points higher). The advantage is based on 1.7 bits higher color depth, 2.5 EV in additional 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 are not only capable of taking still images, but can also record movies. The GR indeed provides for movie recording, while the 20D does not. The highest resolution format that the GR can use is 1080/30p.

 

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the 20D has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the GR relies on live view and the rear LCD for framing. That said, the GR can be equipped with an optional viewfinder – the GV-1. The following table reports on some other key feature differences and similarities of the Canon 20D, the Ricoh GR, and comparable cameras.

One feature that is present on the 20D, but is missing on the GR is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.

The Ricoh GR 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 20D writes its imaging data to Compact Flash cards, while the GR uses SDXC 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 20D and Ricoh GR and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Canon 20D (unlike the GR) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the 20D and the GR have been discontinued, but can regularly be found used on eBay. The 20D was replaced by the Canon 30D, while the GR was followed by the Ricoh GR II. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Ricoh websites.

Review summary

So what is the bottom line? Is the Canon 20D better than the Ricoh GR or vice versa? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Reasons to prefer the Canon EOS 20D:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Easier framing: Has an optical viewfinder for image composition and settings control.
  • Easier setting verification: Features an LCD display on top to control shooting parameters.
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
  • Faster burst: Shoots at higher frequency (5 vs 4 flaps/sec) to capture the decisive moment.
  • More flexible: Can take a variety of interchangeable lenses, including specialty optics.
  • Longer lasting: Can take more shots (700 versus 290) on a single battery charge.
  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • More heavily discounted: Has been available for much longer (launched in August 2004).

ilogo

Arguments in favor of the Ricoh GR:

  • More detail: Has more megapixels (16.1 vs 8.2MP), which boosts linear resolution by 40%.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Better image quality: Scores substantially higher (16 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (1.7 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (2.5 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (0.4 stops ISO advantage).
  • Broader imaging potential: Can capture not only stills but also 1080/30p video.
  • Larger screen: Has a bigger rear LCD (3.0" vs 1.8") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (1230k vs 118k dots).
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • Ready to shoot: Comes with an integrated lens, while the 20D requires a separate lens.
  • More compact: Is smaller (117x61mm vs 144x106mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight even though it has a lens built in (unlike the 20D).
  • Easier travel charging: Can be conveniently charged via its USB port.
  • Faster data transfer: Supports a more advanced USB protocol (2.0 vs 1.1).
  • More affordable: Was introduced at a lower price, despite coming with a built-in lens.
  • More modern: Reflects 8 years and 7 months of technical progress since the 20D launch.

If the count of relative strengths (bullet points above) is taken as a measure, the GR is the clear winner of the contest (16 : 9 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.

20D 09:16 GR

How about other alternatives? Do the specifications of the Canon 20D and the Ricoh GR place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Prime Lens Compact Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the 20D and the GR in practical situations. 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 expert reviews are important. The adjacent summary-table relays the overall verdicts of several of the most popular 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.
