Body comparison: Canon 20D vs Nikon D3400
The side-by-side display below illustrates the physical size and weight of the Canon 20D and the Nikon D3400. 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.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon D3400 is notably smaller (20 percent) than the Canon 20D. Moreover, the D3400 is substantially lighter (42 percent) than the 20D. In this context, it is worth noting that neither the 20D nor the D3400 are weather-sealed.
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 (D3400).
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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.

The price is, of course, an important factor in any camera decision. 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 D3400 was launched at a markedly lower price (by 67 percent) than the 20D, 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.
Sensor comparison: Canon 20D vs Nikon D3400
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. 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 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 D3400 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.
With 24MP, the D3400 offers a higher resolution than the 20D (8.2MP), but the D3400 has smaller individual pixels (pixel pitch of 3.91μm versus 6.42μm for the 20D). Yet, the D3400 is a much more recent model (by 12 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. Coming back to sensor resolution, it should be mentioned that the D3400 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
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 D3400 are ISO 100 to ISO 25600 (no boost).
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. Of the two cameras under consideration, the D3400 offers substantially better image quality than the 20D (overall score 24 points higher). The advantage is based on 2.9 bits higher color depth, 2.9 EV in additional dynamic range, and 0.7 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.

One feature that is present on the 20D, but is missing on the D3400 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 20D writes its imaging data to Compact Flash cards, while the D3400 uses SDXC cards.
Connectivity comparison: Canon 20D vs Nikon D3400

It is notable that the D3400 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the 20D does not offer wifi capability.
Studio photographers will appreciate that the Canon 20D (unlike the D3400) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the 20D and the D3400 have been discontinued, but can regularly be found used on eBay. The 20D was replaced by the Canon 30D, while the D3400 was followed by the Nikon D3500.
Review summary: Canon 20D vs Nikon D3400
So how do things add up? Is the Canon 20D better than the Nikon D3400 or vice versa? The listing below highlights the relative strengths of the two models.
Reasons to prefer the Canon EOS 20D:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Easier setting verification: Features an LCD display on top to control shooting parameters.
- Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
- 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).
Arguments in favor of the Nikon D3400:
- More detail: Has more megapixels (24 vs 8.2MP), which boosts linear resolution by 71%.
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Better image quality: Scores substantially higher (24 points) in the DXO overall evaluation.
- Richer colors: Generates noticeably more natural colors (2.9 bits more color depth).
- More dynamic range: Captures a broader range of light and dark details (2.9 EV of extra DR).
- Better low-light sensitivity: Can shoot in dim conditions (0.7 stops ISO advantage).
- Broader imaging potential: Can capture not only stills but also 1080/60p 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 (921k vs 118k dots).
- More compact: Is smaller (124x98mm vs 144x106mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 325g or 42 percent) and is thus easier to take along.
- Longer lasting: Gets more shots (1200 versus 700) out of a single battery charge.
- Faster data transfer: Supports a more advanced USB protocol (2.0 vs 1.1).
- Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
- Easier wireless transfer: Supports Bluetooth for image sharing without cables.
- More affordable: Was introduced into a lower priced category (67 percent cheaper at launch).
- More modern: Reflects 12 years of technical progress since the 20D launch.
If the count of relative strengths (bullet points above) is taken as a measure, the D3400 is the clear winner of the contest (17 : 5 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision on a new camera.
In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the 20D or the D3400 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.

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