Canon SL2 versus Nikon D3400

The Canon EOS Rebel SL2 (called Canon 200D in some regions) and the Nikon D3400 are two digital cameras that were revealed to the public, respectively, in June 2017 and August 2016. 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: Canon SL2 vs Nikon D3400

An illustration of the physical size and weight of the Canon SL2 and the Nikon D3400 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All size 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 side – the SL2 – represents the basis for the calculations 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 D3400 is notably larger (7 percent) than the Canon SL2. However, the D3400 is slightly lighter (2 percent) than the SL2. In this context, it is worth noting that neither the SL2 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 find an overview of optics for the two cameras in the Canon EF Lens Catalog (SL2) and the Nikon Lens Catalog (D3400).

Concerning battery life, the SL2 gets 650 shots out of its LP-E17 battery, while the D3400 can take 1200 images on a single charge of its EN-EL14a power pack.

The camera’s price is obviously a critical decision-making factor. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

 

Sensor comparison: Canon SL2 vs Nikon D3400

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 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. 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 11 percent bigger. As a result of these sensor size differences, the cameras have format factors, respectively, of 1.6 (SL2) 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 SL2 and Nikon D3400 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.

The SL2 has on-sensor phase detect pixels, which results in relatively fast and reliable autofocus acquisition during video recording.

SL2 versus D3400 MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 has a markedly higher DXO score than the SL2 (overall score 7 points higher), which will translate into better image quality. The 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 adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, and both provide the same movie specifications (1080/60p).

 

Feature comparison: Canon SL2 vs Nikon D3400

Beyond body and sensor, cameras can and do differ across a range of features. The SL2 and the D3400 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 table below summarizes some of the other core capabilities of the Canon SL2 and Nikon D3400 in connection with corresponding information for a sample of similar cameras.

Reasons to prefer the Nikon D3400:

  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Better image quality: Scores markedly higher (7 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (1.2 bits more color depth).
  • Longer lasting: Gets more shots (1200 versus 650) out of a single battery charge.
  • More heavily discounted: Has been on the market for longer (launched in August 2016).

If the count of relative strengths (bullet points above) is taken as a measure, the SL2 emerges as the winner of the contest (8 : 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.

SL2 08:05 D3400

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the SL2 and the D3400 in practical situations. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased. This is where reviews by experts come in. The following table reports the overall rankings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. Thus, a score needs to be put into the context of the launch date and the launch price 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.
