Canon 1D vs 1DX

The Canon EOS-1D and the Canon EOS-1D X are two professional cameras that were revealed to the public, respectively, in September 2001 and October 2011. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-H (1D) and a full frame (1DX) sensor. The 1D has a resolution of 4.1 megapixels, whereas the 1DX provides 17.9 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 and the Canon EOS-1D X? 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

An illustration of the physical size and weight of the Canon 1D and the Canon 1D X is provided in the side-by-side display below. 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.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon 1D X is notably larger (8 percent) than the Canon 1D. However, the 1DX is slightly lighter (2 percent) than the 1D. 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 1DX) will tend to go along with bigger and heavier lenses, while more compact options are available for the smaller-sensor camera (1D). You can compare the optics available in the Canon EF Lens Catalog.

Concerning battery life, the 1D gets 500 shots out of its Canon NP-E3 battery, while the 1DX can take 1120 images on a single charge of its Canon LP-E4N power pack. As can be seen in the images above, both cameras have a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The 1D was somewhat cheaper (by 4 percent) than the 1DX at launch, but both cameras fall into the same price category. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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 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 associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Canon 1D features an APS-H sensor and the Canon 1D X a full frame sensor. The sensor area in the 1DX is 58 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.3 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

With 17.9MP, the 1DX offers a higher resolution than the 1D (4.1MP), but the 1DX has smaller individual pixels (pixel pitch of 6.95μm versus 11.56μm for the 1D). Yet, the 1DX is a much more recent model (by 10 years) than the 1D, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.

The resolution advantage of the Canon 1D X implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 1DX 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 Canon 1D are 12.5 x 8.3 inches or 31.7 x 21.1 cm for good quality, 10 x 6.6 inches or 25.4 x 16.9 cm for very good quality, and 8.3 x 5.5 inches or 21.1 x 14.1 cm for excellent quality prints.

The Canon EOS-1D has a native sensitivity range from ISO 200 to ISO 1600, which can be extended to ISO 100-3200. The corresponding ISO settings for the Canon EOS-1D X are ISO 100 to ISO 51200, with the possibility to increase the ISO range to 50-204800.

In terms of underlying technology, the 1D is build around a CCD sensor, while the 1DX uses a CMOS imager. 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. 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 cannot only take still pictures, but also record videos. The 1DX indeed provides for movie recording, while the 1D does not. The highest resolution format that the 1DX can use is 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The 1D and the 1DX 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 1DX has a higher magnification than the one of the 1D (0.76x vs 0.55x), 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 1D, the Canon 1D X, and comparable cameras.

Concerning the storage of imaging data, both the 1D and the 1DX write their files to Compact Flash cards. The 1DX features dual card slots, which can be very useful in case a memory card fails. In contrast, the 1D 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 and Canon EOS-1D X and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both cameras feature a PC Sync terminal to control professional strobe lights, which will be appreciated by studio photographers.

Both the 1D and the 1DX have been discontinued, but can regularly be found used on ebay. The 1D was replaced by the Canon 1D Mark II, while the 1DX was followed by the Canon 1DX Mark II. Further information on the features and operation of the 1D and 1DX can be found, respectively, in the Canon 1D Manual (free pdf) or the online Canon 1D X Manual.

Review summary

So what is the bottom line? Is there a clear favorite between the Canon 1D and the Canon 1D X? Which camera is better? The listing below highlights the relative strengths of the two models.

Arguments in favor of the Canon EOS-1D:

• Faster shutter: Has higher mechanical shutter speed (1/16000s vs 1/8000s) to freeze action.
• More heavily discounted: Has been available for much longer (launched in September 2001).

Reasons to prefer the Canon EOS-1D X:

• More detail: Has more megapixels (17.9 vs 4.1MP), which boosts linear resolution by 108%.
• Better image quality: Is equipped with a larger and more technologically advanced sensor.
• Richer colors: The sensor size advantage translates into images with better, more accurate colors.
• More dynamic range: Larger sensor captures a wider spectrum of light and dark details.
• Better low-light sensitivity: Larger sensor produces good images even in poorly lit environments.
• Broader imaging potential: Can capture not only stills but also 1080/30p video.
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.76x vs 0.55x).
• Larger screen: Has a bigger rear LCD (3.2" vs 2.0") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (1040k vs 120k dots).
• Faster burst: Shoots at higher frequency (14 vs 8 flaps/sec) to capture the decisive moment.
• Longer lasting: Gets more shots (1120 versus 500) out of a single battery charge.
• Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
• More modern: Reflects 10 years of technical progress since the 1D launch.

If the count of individual advantages (bullet points above) is taken as a guide, the 1DX is the clear winner of the contest (13 : 2 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 Canon 1D and the Canon 1D X 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 technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the 1D or the 1DX perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

This is where reviews by experts come in. 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.

The review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
