Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS 6D Mark II and the Nikon D5100? 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.

Body comparison: Canon 6D Mark II vs Nikon D5100

An illustration of the physical size and weight of the Canon 6D Mark II and the Nikon D5100 is provided in the side-by-side display below. 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 size dimensions are rounded to the nearest millimeter.

Compare 6D Mark II versus D5100 top
Comparison 6D Mark II or D5100 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon D5100 is notably smaller (22 percent) than the Canon 6D Mark II. Moreover, the D5100 is markedly lighter (27 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 D5100 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 (D5100).

Concerning battery life, the 6D Mark II gets 1200 shots out of its LP-E6N battery, while the D5100 can take 660 images on a single charge of its EN-EL14 power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.

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 D5100 was launched at a markedly lower price (by 63 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.

 

Sensor comparison: Canon 6D Mark II vs Nikon D5100

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. 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 tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Canon 6D Mark II features a full frame sensor and the Nikon D5100 an APS-C sensor. The sensor area in the D5100 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.

Canon 6D Mark II and Nikon D5100 sensor measures

With 26MP, the 6D Mark II offers a higher resolution than the D5100 (16.1MP), but the 6D Mark II nevertheless has larger individual pixels (pixel pitch of 5.76μm versus 4.80μm for the D5100) due to its larger sensor. Moreover, the 6D Mark II is a much more recent model (by 6 years and 2 months) than the D5100, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.

The resolution advantage of the Canon 6D Mark II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 6D Mark II for good quality output (200 dots per inch) amounts to 31.2 x 20.8 inch or 79.2 x 52.8 cm, for very good quality (250 dpi) 25 x 16.6 inch or 63.4 x 42.3 cm, and for excellent quality (300 dpi) 20.8 x 13.9 inch or 52.8 x 35.2 cm. The corresponding values for the Nikon D5100 are 24.6 x 16.3 inch or 62.6 x 41.5 cm for good quality, 19.7 x 13.1 inch or 50.1 x 33.2 cm for very good quality, and 16.4 x 10.9 inch or 41.7 x 27.6 cm for excellent quality prints.

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 D5100 are ISO 100 to ISO 6400, with the possibility to increase the ISO range to 100-25600.

6D Mark II versus D5100 MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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"). Of the two cameras under review, the 6D Mark II has a notably higher overall DXO score than the D5100 (overall score 5 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.9 bits higher color depth, 1.7 EV of lower dynamic range, and 1.3 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 cannot only take still pictures, but also record videos. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the 6D Mark II provides a higher frame rate than the D5100. It can shoot video footage at 1080/60p, while the Nikon is limited to 1080/30p.

 

Feature comparison: Canon 6D Mark II vs Nikon D5100

Apart from body and sensor, cameras can and do differ across a range of features. The 6D Mark II and the D5100 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 D5100 (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 0.51x), 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 D5100 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 D5100 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.

Both cameras have an articulated rear screen that can be turned to be front-facing. This feature will be particularly appreciated by vloggers and photographers who are interested in taking selfies.

The Canon 6D Mark II and the Nikon D5100 both have 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 D5100 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.

 

Connectivity comparison: Canon 6D Mark II vs Nikon D5100

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.

  • More compact: Is smaller (128x97mm vs 144x111mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 205g or 27 percent) and is thus easier to take along.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • More affordable: Was introduced into a lower priced category (63 percent cheaper at launch).
  • More heavily discounted: Has been around for much longer (launched in April 2011).

If the count of relative strengths (bullet points above) is taken as a measure, the 6D Mark II is the clear winner of the match-up (17 : 6 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 wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

How about other alternatives? Do the specifications of the Canon 6D Mark II and the Nikon D5100 place the cameras among the top in their class? Find out in the latest Best DSLR Camera listing whether the two cameras rank among the cream of the crop.

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the 6D Mark II or the D5100. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews: Canon 6D Mark II vs Nikon D5100

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 (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (-) not available.

The above review scores should be interpreted 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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
