Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS 10D and the Canon EOS 70D? 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 Canon 10D and the Canon 70D. 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 Canon 70D is notably smaller (10 percent) than the Canon 10D. Moreover, the 70D is markedly lighter (11 percent) than the 10D. It is noteworthy in this context that the 70D is splash and dust-proof, while the 10D 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. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can compare the optics available in the Canon EF Lens Catalog.

Concerning battery life, the 10D gets 500 shots out of its Canon BP-511 battery, while the 70D can take 920 images on a single charge of its Canon LP-E6 power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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 manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The 70D was launched at a markedly lower price (by 40 percent) than the 10D, 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 imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. 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.

Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the 70D is 1 percent smaller. They nevertheless have the same format factor of 1.6. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Technology-wise, the 70D uses a more advanced image processing engine (DIGIC 5+) than the 10D (DIGIC), with benefits for noise reduction, color accuracy, and processing speed.

Despite having a slightly smaller sensor, the 70D offers a higher resolution of 20 megapixels, compared with 6.3 MP of the 10D. 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 4.11μm versus 7.38μm for the 10D). However, it should be noted that the 70D is much more recent (by 10 years and 4 months) than the 10D, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

The resolution advantage of the Canon 70D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 70D for good quality output (200 dots per inch) amounts to 27.4 x 18.2 inches or 69.5 x 46.3 cm, for very good quality (250 dpi) 21.9 x 14.6 inches or 55.6 x 37.1 cm, and for excellent quality (300 dpi) 18.2 x 12.2 inches or 46.3 x 30.9 cm. The corresponding values for the Canon 10D are 15.4 x 10.2 inches or 39 x 26 cm for good quality, 12.3 x 8.2 inches or 31.2 x 20.8 cm for very good quality, and 10.2 x 6.8 inches or 26 x 17.3 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 10D has a native sensitivity range from ISO 100 to ISO 3200. The corresponding ISO settings for the Canon EOS 70D 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 consideration, the 70D offers substantially better image quality than the 10D (overall score 11 points higher). The advantage is based on 1.4 bits higher color depth, 0.7 EV in additional dynamic range, and 0.7 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Note: DXO values in italics represent estimates based on sensor size and age.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The 70D indeed provides for movie recording, while the 10D does not. The highest resolution format that the 70D can use is 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The 10D and the 70D 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 10D (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 0.55x), 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 10D and Canon 70D in connection with corresponding information for a sample of similar cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The 70D has a touchscreen, while the 10D has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The 10D writes its imaging data to Compact Flash cards, while the 70D uses SDXC cards.

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 10D and Canon EOS 70D 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, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the 10D does not provide wifi capability.

Studio photographers will appreciate that the Canon 10D (unlike the 70D) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the 10D and the 70D have been discontinued, but can regularly be found used on ebay. The 10D was replaced by the Canon 20D, while the 70D was followed by the Canon 80D. Further information on the features and operation of the 10D and 70D can be found, respectively, in the Canon 10D Manual (free pdf) or the online Canon 70D Manual.

Review summary

So what is the bottom line? Which of the two cameras – the Canon 10D or the Canon 70D – 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.

Advantages of the Canon EOS 10D:

• 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 February 2003).

Reasons to prefer the Canon EOS 70D:

• More detail: Has more megapixels (20 vs 6.3MP), which boosts linear resolution by 78%.
• Better image quality: Scores substantially higher (11 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 (0.7 EV of extra DR).
• Better low-light sensitivity: Can shoot in dim conditions (0.7 stops ISO advantage).
• Better jpgs: Has a more modern image processing engine (DIGIC 5+ vs DIGIC).
• 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 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 0.55x).
• Larger screen: Has a bigger rear LCD (3.0" vs 1.8") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (1040k vs 118k dots).
• More flexible LCD: Has a swivel screen for odd-angle shots in portrait or 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.
• Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
• Faster burst: Shoots at higher frequency (7 vs 3 flaps/sec) to capture the decisive moment.
• Less heavy: Has a lower weight (by 95g or 11 percent) and is thus easier to take along.
• Longer lasting: Gets more shots (920 versus 500) out of a single battery charge.
• Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
• Faster data transfer: Supports a more advanced USB protocol (2.0 vs 1.1).
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• More affordable: Was introduced into a lower priced category (40 percent cheaper at launch).
• More modern: Reflects 10 years and 4 months of technical progress since the 10D launch.

If the number of relative strengths (bullet points above) is taken as a guide, the 70D is the clear winner of the contest (24 : 2 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 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 10D and the Canon 70D 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 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 10D and the 70D in practical situations. 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 where reviews by experts come in. The adjacent summary-table relays the overall verdicts of several of the most popular camera 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 are only valid when referring 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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
