Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS 70D and the Nikon D3200? 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 physical size and weight of the Canon 70D and the Nikon D3200 are illustrated 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 width, height and depth measures are rounded to the nearest millimeter.

The D3200 can be obtained in two different colors (black, red), while the 70D 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 D3200 is notably smaller (17 percent) than the Canon 70D. Moreover, the D3200 is markedly lighter (33 percent) than the 70D. It is worth mentioning in this context that the 70D is splash and dust resistant, while the D3200 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. 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 (70D) and the Nikon Lens Catalog (D3200).

Concerning battery life, the 70D gets 920 shots out of its LP-E6 battery, while the D3200 can take 540 images on a single charge of its EN-EL14 power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

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 D3200 was launched at a markedly lower price (by 50 percent) than the 70D, 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 sensor inside a digital camera is one of the key determinants 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 more expensive and lead to bigger and heavier cameras and lenses.

Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the D3200 is 6 percent bigger. As a result of these sensor size differences, the cameras have format factors, respectively, of 1.6 (70D) and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

With 24.1MP, the D3200 offers a higher resolution than the 70D (20MP), but the D3200 has smaller individual pixels (pixel pitch of 3.85μm versus 4.11μm for the 70D). It is noteworthy in this context that the 70D is a somewhat more recent model (by 1 year and 2 months) than the D3200, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.

The resolution advantage of the Nikon D3200 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D3200 for good quality output (200 dots per inch) amounts to 30.1 x 20 inches or 76.4 x 50.8 cm, for very good quality (250 dpi) 24.1 x 16 inches or 61.1 x 40.6 cm, and for excellent quality (300 dpi) 20.1 x 13.3 inches or 50.9 x 33.9 cm. The corresponding values for the Canon 70D are 27.4 x 18.2 inches or 69.5 x 46.3 cm for good quality, 21.9 x 14.6 inches or 55.6 x 37.1 cm for very good quality, and 18.2 x 12.2 inches or 46.3 x 30.9 cm for excellent quality prints.

The 70D has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Canon EOS 70D has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 100-25600. The corresponding ISO settings for the Nikon D3200 are ISO 100 to ISO 6400, with the possibility to increase the ISO range to 100-12800.

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 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 D3200 offers substantially better image quality than the 70D (overall score 13 points higher). The advantage is based on 1.6 bits higher color depth, 1.6 EV in additional dynamic range, and 0.3 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 can also record movies. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, and both provide the same movie specifications (1080/30p).

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The 70D and the D3200 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 viewfinder in the 70D offers a wider field of view (98%) than the one in the D3200 (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the 70D has a higher magnification (0.59x vs 0.53x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The following table reports on some other key feature differences and similarities of the Canon 70D, the Nikon D3200, and comparable cameras.

One feature that is present on the 70D, but is missing on the D3200 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.

Concerning the storage of imaging data, both the 70D and the D3200 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 Canon EOS 70D and Nikon D3200 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 70D offers wifi support, while the D3200 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Both the 70D and the D3200 have been discontinued, but can regularly be found used on ebay. The D3200 was replaced by the Nikon D3300, while the 70D was followed by the Canon 80D. Further information on the features and operation of the 70D and D3200 can be found, respectively, in the Canon 70D Manual (free pdf) or the online Nikon D3200 Manual.

Review summary

So what conclusions can be drawn? Which of the two cameras – the Canon 70D or the Nikon D3200 – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.

Reasons to prefer the Canon EOS 70D:

• Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
• More complete view: Has a viewfinder with a larger field of view (98% vs 95%).
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.59x vs 0.53x).
• Easier setting verification: Features an LCD display on top to control shooting parameters.
• More detailed LCD: Has a higher resolution rear screen (1040k vs 921k dots).
• More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
• Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
• Faster burst: Shoots at higher frequency (7 vs 4 flaps/sec) to capture the decisive moment.
• Longer lasting: Can take more shots (920 versus 540) on a single battery charge.
• Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• More modern: Is somewhat more recent (announced 1 year and 2 months after the D3200).

Arguments in favor of the Nikon D3200:

• More detail: Has more megapixels (24.1 vs 20MP), which boosts linear resolution by 10%.
• Better image quality: Scores substantially higher (13 points) in the DXO overall evaluation.
• Richer colors: Generates noticeably more natural colors (1.6 bits more color depth).
• More dynamic range: Captures a broader range of light and dark details (1.6 EV of extra DR).
• More compact: Is smaller (125x96mm vs 139x104mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 250g or 33 percent) and is thus easier to take along.
• More affordable: Was introduced into a lower priced category (50 percent cheaper at launch).
• More heavily discounted: Has been on the market for longer (launched in April 2012).

If the number of relative strengths (bullet points above) is taken as a guide, the 70D is the clear winner of the match-up (14 : 8 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.

How about other alternatives? Do the specifications of the Canon 70D and the Nikon D3200 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 remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the 70D or the D3200. 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.

Care should be taken when interpreting the review scores above, though. The assessments were made in relation to similar cameras of the same technological generation. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
