Canon 7D vs Nikon Df
The Canon EOS 7D and the Nikon Df are two enthusiast cameras that were announced, respectively, in September 2009 and November 2013. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (7D) and a full frame (Df) sensor. The Canon has a resolution of 17.9 megapixels, whereas the Nikon provides 16.2 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 Df? 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 Df 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 size dimensions are rounded to the nearest millimeter.
The Df can be obtained in two different colors (black, silver), while the 7D 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 Df is somewhat smaller (4 percent) than the Canon 7D. Moreover, the Df is markedly lighter (12 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. 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 (7D) and the Nikon Lens Catalog (Df).
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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.

Any camera decision will naturally be influenced heavily by the price. 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 7D was launched at a markedly lower price (by 38 percent) than the Df, 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 size of the imaging sensor is a crucial determinant 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon 7D features an APS-C sensor and the Nikon Df a full frame sensor. The sensor area in the Df is 159 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
Despite having a smaller sensor, the Canon 7D offers a higher resolution of 17.9 megapixels, compared with 16.2 MP of the Nikon Df. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 4.31μm versus 7.29μm for the Df). Moreover, it should be noted that the Df is much more recent (by 4 years and 2 months) than the 7D, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.
The resolution advantage of the Canon 7D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 7D for good quality output (200 dots per inch) amounts to 25.9 x 17.3 inches or 65.8 x 43.9 cm, for very good quality (250 dpi) 20.7 x 13.8 inches or 52.7 x 35.1 cm, and for excellent quality (300 dpi) 17.3 x 11.5 inches or 43.9 x 29.3 cm. The corresponding values for the Nikon Df are 24.6 x 16.4 inches or 62.6 x 41.7 cm for good quality, 19.7 x 13.1 inches or 50.1 x 33.3 cm for very good quality, and 16.4 x 10.9 inches or 41.7 x 27.8 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 Df are ISO 100 to ISO 12800, with the possibility to increase the ISO range to 50-204800.
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"). Of the two cameras under consideration, the Df offers substantially better image quality than the 7D (overall score 23 points higher). The advantage is based on 2.6 bits higher color depth, 1.4 EV in additional dynamic range, and 1.9 stops in additional 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.
|Nikon Df||Full Frame||16.2||4928||3280||none||24.6||13.1||3279||89|

Many modern cameras are not only capable of taking still images, but can also record movies. The 7D indeed provides movie recording capabilities, while the Df does not. The highest resolution format that the 7D can use is 1080/30p.
Beyond body and sensor, cameras can and do differ across a range of features. The 7D and the Df 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%), but the viewfinder of the Df has a higher magnification than the one of the 7D (0.70x vs 0.63x), 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 7D and Nikon Df 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|
One difference between the cameras concerns the presence of an on-board flash. The 7D has one, while the Df does not. While the built-in flash of the 7D is not very powerful, it can at times be useful as a fill-in light.
The Nikon Df 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 Df uses SDXC cards.
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 Df and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

|Canon 5D Mark II||Y||mono||mono||Y||-||mini||2.0||-||-||-|
Both cameras feature a PC Sync terminal to control professional strobe lights, which will be appreciated by studio photographers.
Both the 7D and the Df have been discontinued, but can regularly be found used on eBay. The 7D was replaced by the Canon 7D Mark II, while the Df does not have a direct successor. 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 7D or the Nikon Df – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.
Reasons to prefer the Canon EOS 7D:
- More detail: Offers more megapixels (17.9 vs 16.2MP) with a 5% higher linear resolution.
- Broader imaging potential: Can record not only still images but also 1080/30p movies.
- Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
- Faster burst: Shoots at higher frequency (8 vs 5.5 flaps/sec) to capture the decisive moment.
- Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
- More affordable: Was introduced into a lower priced category (38 percent cheaper at launch).
- More heavily discounted: Has been available for much longer (launched in September 2009).
Advantages of the Nikon Df:
- Better image quality: Scores substantially higher (23 points) in the DXO overall evaluation.
- Richer colors: Generates noticeably more natural colors (2.6 bits more color depth).
- More dynamic range: Captures a broader range of light and dark details (1.4 EV of extra DR).
- Better low-light sensitivity: Can shoot in dim conditions (1.9 stops ISO advantage).
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.70x vs 0.63x).
- Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- Less heavy: Has a lower weight (by 100g or 12 percent) and is thus easier to take along.
- Longer lasting: Gets more shots (1400 versus 800) out of a single battery charge.
- More modern: Reflects 4 years and 2 months of technical progress since the 7D launch.
If the count of individual advantages (bullet points above) is taken as a guide, the Df emerges as the winner of the match-up (10 : 7 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision on a new camera. 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.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the 7D and the Df in practical situations. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.
This is where reviews by experts come in. The following table reports the overall ratings of the cameras as published by some of the major camera 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 were established in reference to similarly priced cameras that were available in the market at the time of the review. A score, therefore, has to be seen in close connection to the price and market introduction time 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.
