If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon 6D Mark II is notably larger (32 percent) than the Nikon D3400. Moreover, the 6D Mark II is substantially heavier (72 percent) than the D3400. It is noteworthy in this context that the 6D Mark II is splash and dust-proof, while the D3400 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 compare the optics available for the two cameras in the Nikon Lens Catalog (D3400) and the Canon EF Lens Catalog (6D Mark II).

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The D3400 was launched at a markedly lower price (by 75 percent) than the 6D Mark II, 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: Nikon D3400 vs Canon 6D Mark II

The size of the sensor inside a digital camera is one of the key determinants of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and 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.

Of the two cameras under consideration, the Nikon D3400 features an APS-C sensor and the Canon 6D Mark II a full frame sensor. The sensor area in the 6D Mark II is 135 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 1.0. 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.

Nikon D3400 and Canon 6D Mark II sensor measures

With 26MP, the 6D Mark II offers a higher resolution than the D3400 (24MP), but the 6D Mark II nevertheless has larger individual pixels (pixel pitch of 5.76μm versus 3.91μm for the D3400) due to its larger sensor. Moreover, the 6D Mark II 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 further 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 6D Mark II has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during video recording.

The Nikon D3400 has a native sensitivity range from ISO 100 to ISO 25600 The corresponding ISO settings for the Canon EOS 6D Mark II are ISO 100 to ISO 40000, with the possibility to increase the ISO range to 50-102400..

One difference between the cameras concerns the presence of an on-board flash. The D3400 has one, while the 6D Mark II does not. While the built-in flash of the D3400 is not very powerful, it can at times be useful as a fill-in light.

The 6D Mark II has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the D3400 does not have a selfie-screen.

Concerning the storage of imaging data, both the D3400 and the 6D Mark II write their files to SDXC cards.

  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • More modern: Was introduced somewhat (10 months) more recently.

If the count of individual advantages (bullet points above) is taken as a guide, the 6D Mark II is the clear winner of the contest (13 : 7 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.

D3400 07:13 6D Mark II

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the D3400 and the 6D Mark II in practical situations. 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 are only valid when referring to cameras in the same category and of the same age. 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, please note that some of the review sites have changed their methodology and reporting over time.
