Canon 1D C vs 70D

The Canon EOS-1D C and the Canon EOS 70D are two digital cameras that were announced, respectively, in April 2012 and July 2013. Both are DSLR (Digital Single Lens Reflex) cameras that are based on a full frame (1DC) and an APS-C (70D) sensor. The 1DC has a resolution of 17.9 megapixels, whereas the 70D provides 20 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-1D C 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 1D C and the Canon 70D. 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.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon 70D is considerably smaller (44 percent) than the Canon 1D C. Moreover, the 70D is substantially lighter (51 percent) than the 1DC. 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 (as in the 1DC) will tend to go along with bigger and heavier lenses, while more compact options are available for the smaller-sensor camera (70D). You can compare the optics available in the Canon EF Lens Catalog.

Concerning battery life, the 1DC gets 1120 shots out of its Canon LP-E4N battery, while the 70D can take 920 images on a single charge of its Canon LP-E6 power pack. As can be seen in the images above, the 1DC has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power. In order to provide similar functionality for the 70D, Canon provides the BG-E14 vertical grip as an optional accessory (see here on ebay).

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

The price is, of course, an important factor in any camera decision. 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 70D was launched at a markedly lower price (by 92 percent) than the 1DC, 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 imaging sensor is a crucial determinant 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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to isolate a subject from the background. On the downside, larger sensors tend to be more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon 1D C features a full frame sensor and the Canon 70D an APS-C sensor. The sensor area in the 70D 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 70D offers a higher resolution of 20 megapixels, compared with 17.9 MP of the 1DC. 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 6.95μm for the 1DC). However, it should be noted that the 70D is a somewhat more recent model (by 1 year and 2 months) than the 1DC, 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 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 1D C 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 70D has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Canon EOS-1D C has a native sensitivity range from ISO 100 to ISO 51200, which can be extended to ISO 50-204800. 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.

For many cameras, data on sensor performance has been reported by DXO Mark. 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"). 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. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the 1DC provides a higher video resolution than the 70D. It can shoot video footage at 4K/24p, while the 70D is limited to 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The 1DC 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 1DC offers a wider field of view (100%) than the one in the 70D (98%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the 1DC has a higher magnification (0.76x vs 0.59x), 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 1D C 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 1DC has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The 1DC writes its imaging data to Compact Flash cards, while the 70D uses SDXC cards. The 1DC features dual card slots, which can be very useful in case a memory card fails. In contrast, the 70D only has one slot.

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-1D C 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 1DC has a headphone jack, which is not present on the 70D This port makes it possible to attach external headphones and monitor the quality of sound during the recording process.

Studio photographers will appreciate that the Canon 1D C (unlike the 70D) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the 1DC and the 70D have been discontinued, but can regularly be found used on ebay. The 70D was replaced by the Canon 80D, while the 1DC does not have a direct successor. Further information on the features and operation of the 1DC and 70D can be found, respectively, in the Canon 1D C Manual (free pdf) or the online Canon 70D Manual.

Review summary

So how do things add up? Is the Canon 1D C better than the Canon 70D or vice versa? Below is a summary of the relative strengths of each of the two contestants.

Advantages of the Canon EOS-1D C:

• Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
• Richer colors: The pixel size advantage translates into images with better, more accurate colors.
• More dynamic range: Larger pixels capture a wider spectrum of light and dark details.
• Better low-light sensitivity: Larger pixels means good image quality even under poor lighting.
• Better video: Provides higher definition movie capture (4K/24p vs 1080/30p).
• Better sound control: Has a headphone port that enables audio monitoring while recording.
• More complete view: Has a viewfinder with a larger field of view (100% vs 98%).
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.76x vs 0.59x).
• Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
• Faster burst: Shoots at higher frequency (14 vs 7 flaps/sec) to capture the decisive moment.
• More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
• Longer lasting: Can take more shots (1120 versus 920) on a single battery charge.
• Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
• Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
• More heavily discounted: Has been on the market for longer (launched in April 2012).

Reasons to prefer the Canon EOS 70D:

• More detail: Has more megapixels (20 vs 17.9MP), which boosts linear resolution by 6%.
• Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
• 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.
• More compact: Is smaller (139x104mm vs 158x164mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 790g or 51 percent) and is thus easier to take along.
• 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.
• More affordable: Was introduced into a lower priced category (92 percent cheaper at launch).
• More modern: Was introduced somewhat (1 year and 2 months) more recently.

If the count of relative strengths (bullet points above) is taken as a measure, the 1DC is the clear winner of the match-up (15 : 11 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 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 1D C 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 remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the 1DC or the 70D. 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.

Expert reviews

This is why hands-on reviews by experts are important. 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.

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 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.
