Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon Df and the Canon EOS M3? 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

The side-by-side display below illustrates the physical size and weight of the Nikon Df and the Canon M3. 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 dimensions are rounded to the nearest millimeter.

The Df can be obtained in two different colors (black, silver), while the M3 is also available in two color-versions, but different ones (black, white).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon M3 is considerably smaller (52 percent) than the Nikon Df. Moreover, the M3 is substantially lighter (52 percent) than the Df. It is worth mentioning in this context that the Df is splash and dust resistant, while the M3 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. Hence, you might want to study and compare the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.

Concerning battery life, the Df gets 1400 shots out of its Nikon EN-EL14 battery, while the M3 can take 250 images on a single charge of its Canon LP-E17 power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The M3 was launched at a markedly lower price (by 75 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.

Sensor comparison

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. 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Nikon Df features a full frame sensor and the Canon M3 an APS-C sensor. The sensor area in the M3 is 61 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 1.6. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Despite having a smaller sensor, the M3 offers a higher resolution of 24 megapixels, compared with 16.2 MP of the 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 3.72μm versus 7.29μm for the Df). However, it should be noted that the M3 is a somewhat more recent model (by 1 year and 3 months) than the Df, and its sensor might have benefitted from technological advances during this time that partly offset its pixel-size disadvantage.

The resolution advantage of the Canon M3 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the M3 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 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 M3 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Nikon Df has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 50-204800. The corresponding ISO settings for the Canon EOS M3 are ISO 100 to ISO 12800, with the possibility to increase the ISO range to 100-25600.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

Consistent information on actual sensor performance is available from DXO Mark for many 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 review, the Df provides substantially higher image quality than the M3, with an overall score that is 17 points higher. This advantage is based on 1.8 bits higher color depth, 1.3 EV in additional dynamic range, and 1.5 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.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The M3 indeed provides for movie recording, while the Df does not. The highest resolution format that the M3 can use is 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the Df has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the M3 relies on live view and the rear LCD for framing. That said, the M3 can be equipped with an optional viewfinder – the EVF-DC1. The following table reports on some other key feature differences and similarities of the Nikon Df, the Canon M3, and comparable cameras.

One feature that is present on the Df, but is missing on the M3 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.

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.

Concerning the storage of imaging data, both the Df and the M3 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

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 Nikon Df and Canon EOS M3 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the M3 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the Df does not provide wifi capability.

Studio photographers will appreciate that the Nikon Df (unlike the M3) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the Df and the M3 have been discontinued, but can regularly be found used on ebay. The M3 was replaced by the Canon M6, while the Df does not have a direct successor. Further information on the features and operation of the Df and M3 can be found, respectively, in the Nikon Df Manual (free pdf) or the online Canon M3 Manual.

Review summary

So what conclusions can be drawn? Which of the two cameras – the Nikon Df or the Canon M3 – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.

Reasons to prefer the Nikon Df:

• Better image quality: Scores substantially higher (17 points) in the DXO overall assessment.
• Richer colors: Generates images with noticeably better colors (1.8 bits more color depth).
• More dynamic range: Captures a larger spectrum of light and dark details (1.3 EV of extra DR).
• Better low-light sensitivity: Requires less light for good images (1.5 stops ISO advantage).
• Easier framing: Has an optical viewfinder for image composition and settings control.
• Easier setting verification: Features an LCD display on top to control shooting parameters.
• Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
• Faster burst: Shoots at higher frequency (5.5 vs 4.2 flaps/sec) to capture the decisive moment.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• Longer lasting: Can take more shots (1400 versus 250) on a single battery charge.
• Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
• Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
• More heavily discounted: Has been on the market for longer (launched in November 2013).

Arguments in favor of the Canon EOS M3:

• More detail: Has more megapixels (24 vs 16.2MP), which boosts linear resolution by 22%.
• Broader imaging potential: Can capture not only stills but also 1080/30p video.
• Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
• More detailed LCD: Has a higher resolution rear screen (1040k vs 921k dots).
• More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
• Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• More compact: Is smaller (111x68mm vs 144x110mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 394g or 52 percent) and is thus easier to take along.
• More legacy lens friendly: Can use many non-native lenses via adapters.
• Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• More affordable: Was introduced into a lower priced category (75 percent cheaper at launch).
• More modern: Was introduced somewhat (1 year and 3 months) more recently.

If the number of relative strengths (bullet points above) is taken as a guide, the M3 emerges as the winner of the match-up (15 : 13 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. 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 Nikon Df and the Canon M3 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Mirrorless Interchangeable Lens Camera listings 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 remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the Df or the M3. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.

Expert reviews

This is why expert reviews are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). 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.

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

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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning.
