Canon 20D versus Nikon Df

The Canon EOS 20D and the Nikon Df are two enthusiast cameras that were officially introduced, respectively, in August 2004 and November 2013. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (20D) and a full frame (Df) sensor. The Canon has a resolution of 8.2 megapixel, whereas the Nikon provides 16.2 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 20D vs Nikon Df

The side-by-side display below illustrates the physical size and weight of the Canon 20D and the Nikon Df. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth 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 20D – 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 Nikon Df is somewhat larger (4 percent) than the Canon 20D. However, the Df is slightly lighter (1 percent) than the 20D. It is noteworthy in this context that the Df is splash and dust-proof, while the 20D 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. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can find an overview of optics for the two cameras in the Canon EF Lens Catalog (20D) and the Nikon Lens Catalog (Df).

Concerning battery life, the 20D gets 700 shots out of its BP-511A battery, while the Df can take 1400 images on a single charge of its EN-EL14 power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

Any camera purchase 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 20D was launched at a markedly lower price (by 45 percent) than the Df, 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 20D vs Nikon Df

The size of the imaging sensor is a crucial determinant of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units in a sensor of the same technological generation. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better isolate a subject from the 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 20D features an APS-C sensor and the Nikon Df a full frame sensor. The sensor area in the Df is 154 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 1.0. 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.

Canon 20D and Nikon Df sensor measures

With 16.2MP, the Df offers a higher resolution than the 20D (8.2MP), but the Df nevertheless has larger individual pixels (pixel pitch of 7.29μm versus 6.42μm for the 20D) due to its larger sensor. Moreover, the Df is a much more recent model (by 9 years and 2 months) than the 20D, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.

20D versus Df 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 Df offers substantially better image quality than the 20D (overall score 27 points higher). The advantage is based on 2.7 bits higher color depth, 2.1 EV in additional dynamic range, and 2.2 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.

The Df offers Live View, so that it can project the live image that the sensor receives onto the rear screen for framing. The 20D lacks this capability. Both cameras are still-image focused and cannot record videos.
 

Feature comparison: Canon 20D vs Nikon Df

Apart from body and sensor, cameras can and do differ across a range of features. The 20D and the Df 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 Canon 20D, the Nikon Df, and comparable cameras. The full specs-sheets can be found in the camera manual or in the dpreview camera hub.

One difference between the cameras concerns the presence of an on-board flash. The 20D has one, while the Df does not. While the build-in flash of the 20D is not very powerful, it can at times be useful as a fill-in light.

The 20D writes its imaging data to Compact Flash cards, while the Df uses SDXC cards.

The Df is a recent model that features in the current product line-up of Nikon. In contrast, the 20D has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the 20D was succeeded by the Canon 30D.

Review summary: Canon 20D vs Nikon Df

So what conclusions can be drawn? Which of the two cameras – the Canon 20D or the Nikon Df – has the upper hand? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Reasons to prefer the Canon EOS 20D:

  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
  • More affordable: Was introduced into a lower priced category (45 percent cheaper at launch).
  • More heavily discounted: Has been available for much longer (launched in August 2004).

ilogo

Arguments in favor of the Nikon Df:

  • More detail: Has more megapixels (16.2 vs 8.2MP), which boosts linear resolution by 41%.
  • Better image quality: Scores substantially higher (27 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (2.7 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (2.1 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (2.2 stops ISO advantage).
  • Larger screen: Has a bigger rear LCD (3.2" vs 1.8") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (921k vs 118k dots).
  • Longer lasting: Gets more shots (1400 versus 700) 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 (2.0 vs 1.1).
  • More modern: Reflects 9 years and 2 months of technical progress since the 20D launch.

If the number of relative strengths (bullet points above) is taken as a guide, the Df is the clear winner of the contest (11 : 4 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.

20D 04:11 Df

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the 20D or the Df. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable. This is why expert reviews are important. The table below summarizes the assessments of some of the best known camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
