Canon 1Ds Mark III vs 30D
The Canon EOS-1Ds Mark III and the Canon EOS 30D are two digital cameras that were announced, respectively, in August 2007 and February 2006. Both are DSLR (Digital Single Lens Reflex) cameras that are based on a full frame (1Ds Mark III) and an APS-C (30D) sensor. The 1Ds Mark III has a resolution of 21 megapixels, whereas the 30D provides 8.2 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 30D? 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 side-by-side display below illustrates the physical size and weight of the Canon 1Ds Mark III and the Canon 30D. 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 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 30D is considerably smaller (36 percent) than the Canon 1Ds Mark III. Moreover, the 30D is substantially lighter (43 percent) than the 1Ds Mark III. It is worth mentioning in this context that the 1Ds Mark III is splash and dust resistant, while the 30D 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 1Ds Mark III) will tend to go along with bigger and heavier lenses, while more compact options are available for the smaller-sensor camera (30D). 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 30D can take 750 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 30D, Canon provides the BG-E2N 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.

Any camera decision will naturally be influenced heavily by the price. 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 30D was launched at a markedly lower price (by 83 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.
The size of the sensor inside a digital camera is one of the key determinants 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. 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 are more costly to manufacture and tend to 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 30D an APS-C sensor. The sensor area in the 30D 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.
With 21MP, the 1Ds Mark III offers a higher resolution than the 30D (8.2MP), but the 1Ds Mark III has marginally smaller individual pixels (pixel pitch of 6.41μm versus 6.42μm for the 30D). However, the 1Ds Mark III is a somewhat more recent model (by 1 year and 5 months) than the 30D, 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 inches or 71.3 x 47.5 cm, for very good quality (250 dpi) 22.5 x 15 inches or 57.1 x 38 cm, and for excellent quality (300 dpi) 18.7 x 12.5 inches or 47.5 x 31.7 cm. The corresponding values for the Canon 30D are 17.5 x 11.7 inches or 44.5 x 29.7 cm for good quality, 14 x 9.3 inches or 35.6 x 23.7 cm for very good quality, and 11.7 x 7.8 inches or 29.7 x 19.8 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 30D are ISO 100 to ISO 1600, with the possibility to increase the ISO range to 100-3200.
For many cameras, data on sensor performance has been reported by DXO Mark. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). Of the two cameras under review, the 1Ds Mark III provides substantially higher image quality than the 30D, with an overall score that is 21 points higher. This advantage is based on 2.5 bits higher color depth, 1.2 EV in additional dynamic range, and 1.2 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.

Apart from body and sensor, cameras can and do differ across a range of features. The 1Ds Mark III and the 30D 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 30D (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 0.56x), 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 1Ds Mark III and Canon 30D along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The 30D has one, while the 1Ds Mark III does not. While the built-in flash of the 30D 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 30D uses Compact Flash cards. The 1Ds Mark III features dual card slots, which can be very useful in case a memory card fails. In contrast, the 30D 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-1Ds Mark III and Canon EOS 30D 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 30D have been discontinued, but can regularly be found used on eBay. The 30D was replaced by the Canon 40D, while the 1Ds Mark III was followed by the Canon 1DX. 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 is the bottom line? Which of the two cameras – the Canon 1Ds Mark III or the Canon 30D – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.
Arguments in favor of the Canon EOS-1Ds Mark III:
- More detail: Offers more megapixels (21 vs 8.2MP) with a 60% higher linear resolution.
- Better image quality: Scores substantially higher (21 points) in the DXO overall assessment.
- Richer colors: Generates images with noticeably better colors (2.5 bits more color depth).
- More dynamic range: Captures a larger spectrum of light and dark details (1.2 EV of extra DR).
- Better low-light sensitivity: Requires less light for good images (1.2 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 0.56x).
- Larger screen: Has a bigger rear LCD (3.0" vs 2.5") for image review and settings control.
- More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
- Longer lasting: Can take more shots (1800 versus 750) 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 modern: Is somewhat more recent (announced 1 year and 5 months after the 30D).
Advantages of the Canon EOS 30D:
- More compact: Is smaller (144x106mm vs 150x160mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 600g or 43 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 (83 percent cheaper at launch).
- More heavily discounted: Has been on the market for longer (launched in February 2006).
If the number of relative strengths (bullet points above) is taken as a guide, the 1Ds Mark III is the clear winner of the match-up (13 : 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 Mark III and the Canon 30D 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 1Ds Mark III and the 30D 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 where reviews by experts come in. The following table reports the overall ratings of the cameras as published by some of the major 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 assessments were made in relation to similar cameras of the same technological generation. 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.
