Canon 1Ds Mark III vs 50D
The Canon EOS-1Ds Mark III and the Canon EOS 50D are two digital cameras that were revealed to the public, respectively, in August 2007 and August 2008. Both are DSLR (Digital Single Lens Reflex) cameras that are based on a full frame (1Ds Mark III) and an APS-C (50D) sensor. The 1Ds Mark III has a resolution of 21 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 Mark III 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: Canon 1Ds Mark III vs 50D
The physical size and weight of the Canon 1Ds Mark III and the Canon 50D are illustrated 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 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 50D is considerably smaller (34 percent) than the Canon 1Ds Mark III. Moreover, the 50D is substantially lighter (41 percent) than the 1Ds Mark III. 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 Mark III) 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 Mark III gets 1800 shots out of its LP-E4 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 Mark III 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).
The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

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 84 percent) than the 1Ds Mark III, which puts it into a different market segment. 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: Canon 1Ds Mark III vs 50D
The size of the imaging sensor is a crucial determinant 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. 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 more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon 1Ds Mark III features a full frame sensor and the Canon 50D an APS-C sensor. The sensor area in the 50D is 62 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.
In terms of underlying technology, both cameras are build around CMOS sensors.
With 21MP, the 1Ds Mark III offers a higher resolution than the 50D (15.1MP), but the 1Ds Mark III nevertheless has larger individual pixels (pixel pitch of 6.41μm versus 4.69μm for the 50D) due to its larger sensor. However, the 50D is a somewhat more recent model (by 1 year) than the 1Ds Mark III, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels.
The resolution advantage of the Canon 1Ds Mark III implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 1Ds Mark III for good quality output (200 dots per inch) amounts to 28.1 x 18.7 inch or 71.3 x 47.5 cm, for very good quality (250 dpi) 22.5 x 15 inch or 57.1 x 38 cm, and for excellent quality (300 dpi) 18.7 x 12.5 inch or 47.5 x 31.7 cm. The corresponding values for the Canon 50D are 23.8 x 15.8 inch or 60.4 x 40.2 cm for good quality, 19 x 12.7 inch or 48.3 x 32.2 cm for very good quality, and 15.8 x 10.6 inch or 40.2 x 26.8 cm for excellent quality prints.
The Canon EOS-1Ds Mark III 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 50D are ISO 100 to ISO 3200, with the possibility to increase the ISO range to 100-12800.
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"). Of the two cameras under review, the 1Ds Mark III provides substantially higher image quality than the 50D, with an overall score that is 17 points higher. This advantage is based on 2.2 bits higher color depth, 0.6 EV in additional dynamic range, and 1.3 stops in additional low light sensitivity. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Feature comparison: Canon 1Ds Mark III vs 50D
Beyond body and sensor, cameras can and do differ across a range of features. The 1Ds Mark III 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 Mark III 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 Mark III 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 1Ds Mark III and Canon 50D in connection with corresponding information for a sample of similar cameras.

One difference between the cameras concerns the presence of an on-board flash. The 50D has one, while the 1Ds Mark III 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.
The 1Ds Mark III writes its imaging data to Compact Flash or SDHC cards, while the 50D uses Compact Flash cards.
Connectivity comparison: Canon 1Ds Mark III vs 50D
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 Mark III 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 Mark III and the 50D have been discontinued, but can regularly be found used on eBay. The 1Ds Mark III was replaced by the Canon 1DX, 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: Canon 1Ds Mark III vs 50D
So what conclusions can be drawn? Which of the two cameras – the Canon 1Ds Mark III or the Canon 50D – 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-1Ds Mark III:
- More detail: Offers more megapixels (21 vs 15.1MP) with a 18% higher linear resolution.
- Better image quality: Scores substantially higher (17 points) in the DXO overall assessment.
- Richer colors: Generates images with noticeably better colors (2.2 bits more color depth).
- More dynamic range: Captures a larger spectrum of light and dark details (0.6 EV of extra DR).
- Better low-light sensitivity: Requires less light for good images (1.3 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 (0.76x vs 0.59x).

Reasons to prefer the Canon EOS 50D:
- More detailed LCD: Has a higher resolution rear screen (920k vs 230k dots).
- Faster burst: Shoots at higher frequency (6.3 vs 5 flaps/sec) to capture the decisive moment.
- More compact: Is smaller (146x108mm vs 150x160mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 563g or 41 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 (84 percent cheaper at launch).
- More modern: Was introduced somewhat (1 year) more recently.
If the number of relative strengths (bullet points above) is taken as a guide, the 1Ds Mark III emerges as the winner of the contest (10 : 7 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 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 1Ds Mark III 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 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 1Ds Mark III and the 50D 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.
Expert reviews: Canon 1Ds Mark III vs 50D
This is why expert reviews 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.

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. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
