Canon 6D Mark II vs Nikon D3400
The Canon EOS 6D Mark II and the Nikon D3400 are two digital cameras that were officially introduced, respectively, in June 2017 and August 2016. Both are DSLR (Digital Single Lens Reflex) cameras that are based on a full frame (6D Mark II) and an APS-C (D3400) sensor. The Canon has a resolution of 26 megapixels, whereas the Nikon provides 24 MP.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.
Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS 6D Mark II and the Nikon D3400? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.
An illustration of the physical size and weight of the Canon 6D Mark II 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 width, height and depth measures are rounded to the nearest millimeter.
The D3400 can be obtained in two different colors (black, red), while the 6D Mark II is only available in black.
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 (24 percent) than the Canon 6D Mark II. Moreover, the D3400 is substantially lighter (42 percent) than the 6D Mark II. It is worth mentioning in this context that the 6D Mark II is splash and dust resistant, 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 Canon EF Lens Catalog (6D Mark II) and the Nikon Lens Catalog (D3400).
The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

Any camera decision 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 launched at a markedly lower price (by 75 percent) than the 6D Mark II, which puts it into a different market segment. 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.
The size of the imaging sensor is a crucial determinant 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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its background. On the downside, larger sensors are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon 6D Mark II features a full frame sensor and the Nikon D3400 an APS-C sensor. The sensor area in the D3400 is 57 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
With 26MP, the 6D Mark II offers a slightly 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 pixels. 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 live view operation.
The Canon EOS 6D Mark II has a native sensitivity range from ISO 100 to ISO 40000, which can be extended to ISO 50-102400. The corresponding ISO settings for the Nikon D3400 are ISO 100 to ISO 25600 (no boost).
Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. 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. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, and both provide the same movie specifications (1080/60p).
Beyond body and sensor, cameras can and do differ across a range of features. The 6D Mark II 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 viewfinder in the 6D Mark II offers a wider field of view (98%) than the one in the D3400 (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the 6D Mark II has a higher magnification (0.72x vs 0.57x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Canon 6D Mark II and Nikon D3400 in connection with corresponding information for a sample of similar cameras.

One feature that is present on the 6D Mark II, 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 6D Mark II has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the D3400 does not have a selfie-screen.
The Canon 6D Mark II has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.
Concerning the storage of imaging data, both the 6D Mark II and the D3400 write their files to SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.
For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Canon EOS 6D Mark II and Nikon D3400 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 6D Mark II has a microphone port, which is missing on the D3400. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.
Travel and landscape photographers will find it useful that the 6D Mark II has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.
The 6D Mark II is a recent model that features in the current product line-up of Canon. In contrast, the D3400 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the D3400 was succeeded by the Nikon D3500. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Nikon websites.
So what conclusions can be drawn? Which of the two cameras – the Canon 6D Mark II or the Nikon D3400 – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.

If the count of individual advantages (bullet points above) is taken as a guide, the 6D Mark II is the clear winner of the match-up (18 : 7 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. A professional wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it says little about, for example, the shooting experience and imaging performance of the 6D Mark II 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 table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (amateurphotographer [AP], cameralabs [CL], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier point that a camera decision is often a very personal choice.

The review scores listed above should be treated with care, 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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
