Nikon D3400 versus Canon SL2

The Nikon D3400 and the Canon EOS Rebel SL2 (labelled Canon 200D in some countries) are two digital cameras that were revealed to the public, respectively, in August 2016 and June 2017. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. Both cameras offer a resolution of 24 megapixel. 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: Nikon D3400 vs Canon SL2

The side-by-side display below illustrates the physical size and weight of the Nikon D3400 and the Canon SL2. 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. You can also use the toggle button to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left – the D3400 – 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 Canon SL2 is notably smaller (7 percent) than the Nikon D3400. However, the SL2 is slightly heavier (2 percent) than the D3400. In this context, it is worth noting that neither the D3400 nor the SL2 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 find an overview of optics for the two cameras in the Nikon Lens Catalog (D3400) and the Canon EF Lens Catalog (SL2).

Concerning battery life, the D3400 gets 1200 shots out of its EN-EL14a battery, while the SL2 can take 650 images on a single charge of its LP-E17 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 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 D3400 was somewhat cheaper (by 9 percent) than the SL2 at launch, but both cameras fall into the same price category. 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: Nikon D3400 vs Canon SL2

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. 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 are more costly to manufacture and tend to 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 SL2 is 10 percent smaller. As a result of these sensor size differences, the cameras have format factors, respectively, of 1.5 (D3400) and 1.6. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Nikon D3400 and Canon SL2 sensor measures

Even though the D3400 has a larger sensor, both cameras offer the same resolution of 24 megapixel. This implies that the D3400 has a lower pixel density and larger individual pixels (with a pixel pitch of 3.91μm versus 3.72μm for the SL2), which gives it a potential advantage in terms of light gathering capacity. It should, however, be noted that the SL2 is a somewhat more recent model (by 10 months) than the D3400, and its sensor might have benefitted from technological advances during this time that at least partly compensate for the smaller pixel size. 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.

D3400 versus SL2 MP

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 review, the D3400 has a notably higher overall DXO score than the SL2 (overall score 7 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 1.2 bits higher color depth, 0.5 EV in additional dynamic range, and 0.2 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

If the count of relative strengths (bullet points above) is taken as a measure, the match-up finishes in a tie (5 points each). 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.

D3400 05:05 SL2

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 D3400 or the SL2 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. This is why hands-on reviews by experts are important. The adjacent table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

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. 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.
