Canon 1D Mark IV versus Nikon D7100

The Canon EOS-1D Mark IV and the Nikon D7100 are two digital cameras that were revealed to the public, respectively, in October 2009 and February 2013. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-H (1D Mark IV) and an APS-C (D7100) sensor. The Canon has a resolution of 16 megapixel, whereas the Nikon provides 24 MP. 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 1D Mark IV vs Nikon D7100

An illustration of the physical size and weight of the Canon 1D Mark IV and the Nikon D7100 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 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 1D Mark IV – represents 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 considerably smaller (41 percent) than the Canon 1D Mark IV. Moreover, the D7100 is substantially lighter (38 percent) than the 1D Mark IV. 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 (1D Mark IV) and the Nikon Lens Catalog (D7100).

Concerning battery life, the 1D Mark IV gets 1500 shots out of its LP-E4 battery, while the D7100 can take 950 images on a single charge of its EN-EL15 power pack.

The camera’s price is obviously a critical decision-making factor. 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 D7100 was launched at a markedly lower price (by 76 percent) than the 1D Mark IV, 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: Canon 1D Mark IV vs Nikon D7100

The size of the imaging sensor is a crucial determinant of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have richer color-depth than smaller pixels 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 associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Canon 1D Mark IV features an APS-H sensor and the Nikon D7100 an APS-C sensor. The sensor area in the D7100 is 29 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.3 and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Despite having a smaller sensor, the D7100 offers a higher resolution of 24 megapixel, compared with 16 MP of the 1D Mark IV. 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 5.70μm for the 1D Mark IV). However, it should be noted that the D7100 is much more recent (by 3 years and 4 months) than the 1D Mark IV, 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.

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 consideration, the D7100 has a markedly higher DXO score than the 1D Mark IV (overall score 9 points higher), which will translate into better image quality. The advantage is based on 1.4 bits higher color depth, 1.7 EV in additional dynamic range, 0.1 stops of reduced low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the D7100 provides a faster frame rate than the 1D Mark IV. It can shoot movie footage at 1080/60p, while the Canon is limited to 1080/30p.

Feature comparison: Canon 1D Mark IV vs Nikon D7100

Beyond body and sensor, cameras can and do differ across a range of features. The 1D Mark IV 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 1D Mark IV, the Nikon D7100, and comparable cameras. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

Both the 1D Mark IV and the D7100 have been discontinued, but can regularly be found used on eBay. The D7100 was replaced by the Nikon D7200, while the 1D Mark IV does not have a direct successor.

Review summary: Canon 1D Mark IV vs Nikon D7100

So what is the bottom line? Is the Canon 1D Mark IV better than the Nikon D7100 or vice versa? Below is a summary of the relative strengths of each of the two contestants.

Reasons to prefer the Canon EOS-1D Mark IV:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Faster burst: Shoots at higher frequency (10 vs 6 flaps/sec) to capture the decisive moment.
• Longer lasting: Can take more shots (1500 versus 950) on a single battery charge.
• More heavily discounted: Has been available for much longer (launched in October 2009).

Arguments in favor of the Nikon D7100:

• More detail: Has more megapixels (24 vs 16MP), which boosts linear resolution by 23%.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Better image quality: Scores markedly higher (9 points) in the DXO overall evaluation.
• Richer colors: Generates noticeably more natural colors (1.4 bits more color depth).
• More dynamic range: Captures a broader range of light and dark details (1.7 EV of extra DR).
• Better video: Provides higher movie framerates (1080/60p versus 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).
• More compact: Is smaller (136x107mm vs 156x157mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 465g or 38 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 (76 percent cheaper at launch).
• More modern: Reflects 3 years and 4 months of technical progress since the 1D Mark IV launch.

If the count of relative strengths (bullet points above) is taken as a measure, the D7100 is the clear winner of the contest (13 : 4 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera.

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 1D Mark IV 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 expert reviews are important. The table below summarizes the assessments of some of the best known camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The above review scores should be interpreted with care, though. The ratings are only valid when refering to cameras in the same category and of the same age. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
