Canon 20D vs Nikon D300
The Canon EOS 20D and the Nikon D300 are two enthusiast cameras that were announced, respectively, in August 2004 and August 2007. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The Canon has a resolution of 8.2 megapixels, whereas the Nikon provides 12.2 MP. Read on to find out how these two cameras compare with respect to their body size, their sensors, their features, their input-output connections, and their reception by expert reviewers.

Body comparison: Canon 20D vs Nikon D300
The side-by-side display below illustrates the physical size and weight of the Canon 20D and the Nikon D300. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth measures are rounded to the nearest millimeter.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon D300 is notably larger (10 percent) than the Canon 20D. Moreover, the D300 is markedly heavier (20 percent) than the 20D. It is noteworthy in this context that the D300 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. Yet, since both cameras are based around an APS-C sensor, their respective lenses will tend to have similar dimensions and heft. You can compare the optics available for the two cameras in the Canon EF Lens Catalog (20D) and the Nikon Lens Catalog (D300).
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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. Alternatively, you can also navigate to the CAM-parator app and make your selection from the full list of cameras there.

Any camera decision will obviously take relative prices into account. 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 20D was launched at a somewhat lower price (by 17 percent) than the D300, which makes it more attractive for photographers on a tight budget. 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: Canon 20D vs Nikon D300
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. 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.
Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the D300 is 10 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.
With 12.2MP, the D300 offers a higher resolution than the 20D (8.2MP), but the D300 has smaller individual pixels (pixel pitch of 5.53μm versus 6.42μm for the 20D). Yet, the D300 is a much more recent model (by 3 years) 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.
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 Nikon D300 are ISO 200 to ISO 3200, with the possibility to increase the ISO range to 100-6400..
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 D300 has a markedly higher DXO score than the 20D (overall score 5 points higher), which will translate into better image quality. The advantage is based on 0.2 bits higher color depth, 1 EV in additional dynamic range, and 0.1 stops of reduced low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Feature comparison: Canon 20D vs Nikon D300
Apart from body and sensor, cameras can and do differ across a variety of features. The 20D and the D300 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.

Both cameras feature a PC Sync terminal to control professional strobe lights, which will be appreciated by studio photographers.
Both the 20D and the D300 have been discontinued, but can regularly be found used on eBay. The 20D was replaced by the Canon 30D, while the D300 was followed by the Nikon D300S.
Review summary: Canon 20D vs Nikon D300
So how do things add up? Is there a clear favorite between the Canon 20D and the Nikon D300? The listing below highlights the relative strengths of the two models.
Reasons to prefer the Canon EOS 20D:
- Less heavy: Is lighter (by 155g or 17 percent) and hence easier to carry around.
- More affordable: Was introduced into a lower priced segment (17 percent cheaper at launch).
- More heavily discounted: Has been available for much longer (launched in August 2004).
Advantages of the Nikon D300:
- More detail: Has more megapixels (12.2 vs 8.2MP), which boosts linear resolution by 22%.
- Better image quality: Scores markedly higher (5 points) in the DXO overall evaluation.
- More dynamic range: Captures a broader range of light and dark details (1 EV of extra DR).
- 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 (922k vs 118k dots).
- Faster burst: Shoots at higher frequency (6 vs 5 flaps/sec) to capture the decisive moment.
- Longer lasting: Gets more shots (1000 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 3 years of technical progress since the 20D launch.
If the number of relative strengths (bullet points above) is taken as a guide, the D300 is the clear winner of the contest (10 : 3 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision.
In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the 20D or the D300 handle or perform in practice. 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.

The above review scores should be interpreted with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
