Canon 5D Mark II versus Nikon D7100

The Canon EOS 5D Mark II and the Nikon D7100 are two digital cameras that were officially introduced, respectively, in September 2008 and February 2013. Both are DSLR (Digital Single Lens Reflex) cameras that are based on a full frame (5D Mark II) and an APS-C sensor. The Canon has a resolution of 21 megapixel, whereas the Nikon provides 24 MP.

Body comparison

The physical size and weight of the Canon 5D Mark II and the Nikon D7100 are illustrated in the side-by-side display below. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth measures 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 – the 5D Mark II – represents the basis or 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 Nikon D7100 is notably smaller (16 percent) than the Canon 5D Mark II. Moreover, the D7100 is markedly lighter (10 percent) than the 5D Mark II. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.

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 find an overview of optics for the two cameras in the Canon EF Lens Catalog (5D Mark II) and the Nikon Lens Catalog (D7100).

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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 comparisons there.

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The D7100 was launched at a markedly lower price (by 66 percent) than the 5D 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

Sensor comparison

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. 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 Canon 5D Mark II features a full frame sensor and the Nikon D7100 an APS-C sensor. The sensor area in the D7100 is 58 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.

Sensor size

Despite having a smaller sensor, the D7100 offers a higher resolution of 24 megapixel, compared with 21 MP of the 5D Mark II. This megapixel advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.91μm versus 6.41μm for the 5D Mark II). However, it should be noted that the D7100 is much more recent (by 4 years and 5 months) than the 5D Mark II, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently. Coming back to sensor resolution, it should be mentioned that the D7100 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

Sensor resolution

Consistent information on actual sensor performance is available from DXO Mark for most cameras. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). Of the two cameras under consideration, the D7100 has a markedly higher DXO score than the 5D Mark II (overall score 4 points higher), which will translate into better image quality. The advantage is based on 0.5 bits higher color depth, 1.8 EV in additional dynamic range, 0.5 stops of reduced low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

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 D7100 provides a faster frame rate than the 5D Mark II. It can shoot movie footage at 1080/60p, while the Canon is limited to 1080/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The 5D Mark II and the D7100 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 following table reports on some other key feature differences and similarities of the Canon 5D Mark II, the Nikon D7100, and comparable cameras.

Both the 5D Mark II and the D7100 have been discontinued, but can regularly be found used on ebay. The 5D Mark II was replaced by the Canon 5D Mark III, while the D7100 was followed by the Nikon D7200.

Summary

So what is the bottom line? Is the Canon 5D Mark II better than the Nikon D7100 or vice versa? A synthesis of the relative strong points of each of the models is listed below.


logo checkmark

Arguments in favor of the Canon EOS 5D Mark II:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Better low-light sensitivity: Requires less light for good images (0.5 stops ISO advantage).
  • More heavily discounted: Has been available for much longer (launched in September 2008).

logo checkmark

Reasons to prefer the Nikon D7100:

  • More detail: Has more megapixels (24 vs 21MP), which boosts linear resolution by 7%.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Better image quality: Scores markedly higher (4 points) in the DXO overall evaluation.
  • More dynamic range: Captures a broader range of light and dark details (1.8 EV of extra DR).
  • Better video: Provides higher movie framerates (1080/60p vs 1080/30p).
  • Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (1229k vs 920k dots).
  • Faster burst: Shoots at higher frequency (6 vs 3.9 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (136x107mm vs 152x114mm) and will fit more readily into a bag.
  • Longer lasting: Gets more shots (950 versus 850) out of a single battery charge.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • More affordable: Was introduced into a lower priced category (66 percent cheaper at launch).
  • More modern: Reflects 4 years and 5 months of technical progress since the 5D Mark II launch.

If the count of individual advantages (bullet points above) is taken as a guide, the D7100 is the clear winner of the contest (13 : 3 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.

5D Mark II 03:13 D7100

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the 5D Mark II and the D7100 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 why hands-on reviews by experts are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites. You can find the full text of the reviews, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
