Canon 7D vs Nikon D7100
The Canon EOS 7D and the Nikon D7100 are two enthusiast cameras that were officially introduced, respectively, in September 2009 and February 2013. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The Canon has a resolution of 17.9 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 7D and the Nikon D7100? 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 7D and the Nikon D7100 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth measures are rounded to the nearest millimeter.
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 (11 percent) than the Canon 7D. Moreover, the D7100 is markedly lighter (11 percent) than the 7D. 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. Yet, since both cameras are based around an APS-C sensor, their respective lenses will tend to have similar dimensions and heft. You can compare the optics available for the two cameras in the Canon EF Lens Catalog (7D) and the Nikon Lens Catalog (D7100).

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 D7100 was launched at a markedly lower price (by 29 percent) than the 7D, 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.
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 tend to be associated with larger, more expensive camera bodies and lenses.
Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the D7100 is 11 percent bigger. As a result of these sensor size differences, the cameras have format factors, respectively, of 1.6 (7D) and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
With 24MP, the D7100 offers a higher resolution than the 7D (17.9MP), but the D7100 has smaller individual pixels (pixel pitch of 3.91μm versus 4.31μm for the 7D). Yet, the D7100 is a much more recent model (by 3 years and 5 months) than the 7D, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units. 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.
The resolution advantage of the Nikon D7100 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D7100 for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the Canon 7D are 25.9 x 17.3 inches or 65.8 x 43.9 cm for good quality, 20.7 x 13.8 inches or 52.7 x 35.1 cm for very good quality, and 17.3 x 11.5 inches or 43.9 x 29.3 cm for excellent quality prints.
The Canon EOS 7D has a native sensitivity range from ISO 100 to ISO 6400, which can be extended to ISO 100-12800. The corresponding ISO settings for the Nikon D7100 are ISO 100 to ISO 6400, with the possibility to increase the ISO range to 50-25600.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. Of the two cameras under consideration, the D7100 offers substantially better image quality than the 7D (overall score 17 points higher). The advantage is based on 2.2 bits higher color depth, 2 EV in additional dynamic range, and 0.6 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.
|Canon 7D II||APS-C||20.0||5472||3648||1080/60p||22.4||11.8||1082||70|
|Canon 5D Mark II||Full Frame||21.0||5616||3744||1080/30p||23.7||11.9||1815||79|
Many modern cameras are not only capable of taking still images, but also of capturing video footage. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the D7100 provides a faster frame rate than the 7D. It can shoot movie footage at 1080/60p, while the Canon is limited to 1080/30p.
Beyond body and sensor, cameras can and do differ across a range of features. The 7D 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 viewfinders of both cameras offer the same field of view (100%), as well as the same magnification (0.63x). The table below summarizes some of the other core capabilities of the Canon 7D and Nikon D7100 in connection with corresponding information for a sample of similar cameras.
|Canon 7D II||optical||Y||3.0||1040||fixed||n||1/8000s||10.0||Y||n|
|Canon 5D Mark II||optical||Y||3.0||920||fixed||n||1/8000s||3.9||n||n|
The Nikon D7100 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.
The 7D writes its imaging data to Compact Flash cards, while the D7100 uses SDXC cards. The D7100 features dual card slots, which can be very useful in case a memory card fails. In contrast, the 7D only has one slot.
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 7D and Nikon D7100 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the D7100 has a headphone jack, which makes it possible to attach external headphones and monitor the quality of sound during the recording process. The 7D lacks such a headphone port.
Studio photographers will appreciate that the Canon 7D (unlike the D7100) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the 7D and the D7100 have been discontinued, but can regularly be found used on eBay. The 7D was replaced by the Canon 7D Mark II, while the D7100 was followed by the Nikon D7200. 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? Is the Canon 7D better than the Nikon D7100 or vice versa? Below is a summary of the relative strengths of each of the two contestants.
Advantages of the Canon EOS 7D:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Faster burst: Shoots at higher frequency (8 vs 6 flaps/sec) to capture the decisive moment.
- Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
- More heavily discounted: Has been available for much longer (launched in September 2009).
Reasons to prefer the Nikon D7100:
- More detail: Has more megapixels (24 vs 17.9MP), which boosts linear resolution by 16%.
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Better image quality: Scores substantially higher (17 points) in the DXO overall evaluation.
- Richer colors: Generates noticeably more natural colors (2.2 bits more color depth).
- More dynamic range: Captures a broader range of light and dark details (2 EV of extra DR).
- Better low-light sensitivity: Can shoot in dim conditions (0.6 stops ISO advantage).
- Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
- Better sound control: Has a headphone port that enables audio monitoring while recording.
- 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).
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- More compact: Is smaller (136x107mm vs 148x111mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 95g or 11 percent) and is thus easier to take along.
- Longer lasting: Gets more shots (950 versus 800) out of a single battery charge.
- Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
- More affordable: Was introduced into a lower priced category (29 percent cheaper at launch).
- More modern: Reflects 3 years and 5 months of technical progress since the 7D launch.
If the count of individual advantages (bullet points above) is taken as a guide, the D7100 is the clear winner of the contest (17 : 4 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.
How about other alternatives? Do the specifications of the Canon 7D and the Nikon D7100 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 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 7D 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 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.

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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
