Canon 1D Mark II vs 20D
The Canon EOS-1D Mark II and the Canon EOS 20D are two digital cameras that were revealed to the public, respectively, in January 2004 and August 2004. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-H (1D Mark II) and an APS-C (20D) sensor. Both cameras offer a resolution of 8.2 megapixels.
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 Mark II and the Canon EOS 20D? 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.
The physical size and weight of the Canon 1D Mark II and the Canon 20D are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. 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 20D is considerably smaller (38 percent) than the Canon 1D Mark II. Moreover, the 20D is substantially lighter (50 percent) than the 1D Mark II. It is worth mentioning in this context that the 1D Mark II is splash and dust resistant, while the 20D 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. A larger imaging sensor (as in the 1D Mark II) will tend to go along with bigger and heavier lenses, while more compact options are available for the smaller-sensor camera (20D). You can compare the optics available in the Canon EF Lens Catalog.
Concerning battery life, the 1D Mark II gets 1200 shots out of its NP-E3 battery, while the 20D can take 700 images on a single charge of its BP-511A power pack. As can be seen in the images above, the 1D Mark II 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 20D, Canon provides the BG-E2N vertical grip as an optional accessory (see here on eBay).
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

|Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.|
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 20D was launched at a markedly lower price (by 67 percent) than the 1D Mark II, 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.
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon 1D Mark II features an APS-H sensor and the Canon 20D an APS-C sensor. The sensor area in the 20D is 38 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.3 and 1.6. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
Even though the 1D Mark II has a larger sensor, both cameras offer the same resolution of 8.2 megapixels. This implies that the 1D Mark II has a lower pixel density and larger individual pixels (with a pixel pitch of 8.17μm versus 6.42μm for the 20D), which gives it a potential advantage in terms of light gathering capacity. It should, however, be noted that the 20D is a somewhat more recent model (by 6 months) than the 1D Mark II, and its sensor might have benefitted from technological advances during this time that at least partly compensate for the smaller pixel size.
The Canon EOS-1D Mark II has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 50-3200. The corresponding ISO settings for the Canon EOS 20D are ISO 100 to ISO 1600, with the possibility to increase the ISO range to 100-3200.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 1D Mark II has a notably higher overall DXO score than the 20D (overall score 4 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.4 bits higher color depth, 0.1 EV in additional dynamic range, and 0.5 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.

Beyond body and sensor, cameras can and do differ across a range of features. The 1D Mark II and the 20D 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 1D Mark II offers a wider field of view (100%) than the one in the 20D (95%), so that a larger proportion of the captured image is visible in the finder. On the other hand, the viewfinder of the 20D has a higher magnification (0.56x vs 0.55x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The adjacent table lists some of the other core features of the Canon 1D Mark II and Canon 20D along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The 20D has one, while the 1D Mark II does not. While the built-in flash of the 20D is not very powerful, it can at times be useful as a fill-in light.
The 1D Mark II writes its imaging data to Compact Flash or SD cards, while the 20D uses Compact Flash cards. The 1D Mark II features dual card slots, which can be very useful in case a memory card fails. In contrast, the 20D only has one slot.
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 Mark II and Canon EOS 20D 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 Mark II and the 20D have been discontinued, but can regularly be found used on eBay. The 1D Mark II was replaced by the Canon 1D Mark II N, while the 20D was followed by the Canon 30D. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.
So what conclusions can be drawn? Is there a clear favorite between the Canon 1D Mark II and the Canon 20D? Which camera is better? The listing below highlights the relative strengths of the two models.
Arguments in favor of the Canon EOS-1D Mark II:
- Better image quality: Scores markedly higher (4 points) in the DXO overall assessment.
- Better low-light sensitivity: Requires less light for good images (0.5 stops ISO advantage).
- More complete view: Has a viewfinder with a larger field of view (100% vs 95%).
- Larger screen: Has a bigger rear LCD (2.0" vs 1.8") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (230k vs 118k dots).
- Faster burst: Shoots at higher frequency (8.3 vs 5 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 (1200 versus 700) on a single battery charge.
- Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
- 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 January 2004).
Advantages of the Canon EOS 20D:
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.56x vs 0.55x).
- More compact: Is smaller (144x106mm vs 156x158mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 765g or 50 percent) and is thus easier to take along.
- Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
- More affordable: Was introduced into a lower priced category (67 percent cheaper at launch).
- More modern: Was introduced somewhat (6 months) more recently.
If the count of relative strengths (bullet points above) is taken as a measure, the 1D Mark II is the clear winner of the match-up (11 : 6 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 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 1D Mark II and the Canon 20D 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 says little about, for example, the shooting experience and imaging performance of the 1D Mark II and the 20D in practical situations. 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.
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 (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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 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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
