Canon 1Ds vs 50D

The Canon EOS-1Ds and the Canon EOS 50D are two digital cameras that were officially introduced, respectively, in September 2002 and August 2008. Both are DSLR (Digital Single Lens Reflex) cameras that are based on a full frame (1Ds) and an APS-C (50D) sensor. The 1Ds has a resolution of 11 megapixels, whereas the 50D provides 15.1 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-1Ds and the Canon EOS 50D? 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 1Ds and the Canon 50D. 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 50D is considerably smaller (36 percent) than the Canon 1Ds. Moreover, the 50D is substantially lighter (35 percent) than the 1Ds. 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 1Ds) will tend to go along with bigger and heavier lenses, while more compact options are available for the smaller-sensor camera (50D). You can compare the optics available in the Canon EF Lens Catalog.

Concerning battery life, the 1Ds gets 600 shots out of its NP-E3 battery, while the 50D can take 800 images on a single charge of its BP-511A power pack. As can be seen in the images above, the 1Ds 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 50D, Canon provides the BG-E2N vertical grip as an optional accessory (see here on eBay).

Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The 50D was launched at a markedly lower price (by 86 percent) than the 1Ds, 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 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. 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 1Ds features a full frame sensor and the Canon 50D an APS-C sensor. The sensor area in the 50D 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.

Technology-wise, the 50D uses a more advanced image processing engine (DIGIC 4) than the 1Ds (DIGIC), with benefits for noise reduction, color accuracy, and processing speed.

Despite having a smaller sensor, the 50D offers a higher resolution of 15.1 megapixels, compared with 11 MP of the 1Ds. 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 4.69μm versus 8.83μm for the 1Ds). However, it should be noted that the 50D is much more recent (by 5 years and 11 months) than the 1Ds, 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 50D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 50D for good quality output (200 dots per inch) amounts to 23.8 x 15.8 inch or 60.4 x 40.2 cm, for very good quality (250 dpi) 19 x 12.7 inch or 48.3 x 32.2 cm, and for excellent quality (300 dpi) 15.8 x 10.6 inch or 40.2 x 26.8 cm. The corresponding values for the Canon 1Ds are 20.3 x 13.5 inch or 51.6 x 34.3 cm for good quality, 16.3 x 10.8 inch or 41.3 x 27.5 cm for very good quality, and 13.5 x 9 inch or 34.4 x 22.9 cm for excellent quality prints.

The Canon EOS-1Ds has a native sensitivity range from ISO 100 to ISO 1250, which can be extended to ISO 50-1250. The corresponding ISO settings for the Canon EOS 50D are ISO 100 to ISO 3200, with the possibility to increase the ISO range to 100-12800.

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"). The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The 1Ds and the 50D 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 1Ds offers a wider field of view (100%) than the one in the 50D (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the 1Ds has a higher magnification (0.70x vs 0.59x), 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 1Ds, the Canon 50D, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The 50D has one, while the 1Ds does not. While the built-in flash of the 50D is not very powerful, it can at times be useful as a fill-in light.

Concerning the storage of imaging data, both the 1Ds and the 50D write their files to Compact Flash 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-1Ds and Canon EOS 50D 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 1Ds and the 50D have been discontinued, but can regularly be found used on eBay. The 1Ds was replaced by the Canon 1Ds Mark II, while the 50D was followed by the Canon 60D. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.

Review summary

So what conclusions can be drawn? Which of the two cameras – the Canon 1Ds or the Canon 50D – 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-1Ds:

• 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 viewfinder image: Features a viewfinder with a higher magnification (0.70x vs 0.59x).
• More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
• More heavily discounted: Has been available for much longer (launched in September 2002).

Arguments in favor of the Canon EOS 50D:

• More detail: Has more megapixels (15.1 vs 11MP), which boosts linear resolution by 17%.
• Better jpgs: Has a more modern image processing engine (DIGIC 4 vs DIGIC).
• Larger screen: Has a bigger rear LCD (3.0" vs 2.0") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (920k vs 120k dots).
• Faster burst: Shoots at higher frequency (6.3 vs 3 flaps/sec) to capture the decisive moment.
• More compact: Is smaller (146x108mm vs 156x158mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 443g or 35 percent) and is thus easier to take along.
• Longer lasting: Gets more shots (800 versus 600) out of a single battery charge.
• Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
• More affordable: Was introduced into a lower priced category (86 percent cheaper at launch).
• More modern: Reflects 5 years and 11 months of technical progress since the 1Ds launch.

If the number of relative strengths (bullet points above) is taken as a guide, the 50D is the clear winner of the contest (11 : 5 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 1Ds and the Canon 50D 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 1Ds or the 50D. 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 (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.

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
