Canon 1D vs 30D

The Canon EOS-1D and the Canon EOS 30D are two digital cameras that were announced, respectively, in September 2001 and February 2006. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-H (1D) and an APS-C (30D) sensor. The 1D has a resolution of 4.1 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-1D 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.

Body comparison

An illustration of the physical size and weight of the Canon 1D and the Canon 30D is provided 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 30D is considerably smaller (38 percent) than the Canon 1D. Moreover, the 30D is substantially lighter (50 percent) than the 1D. It is worth mentioning in this context that the 1D 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 1D) 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 1D gets 500 shots out of its NP-E3 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 1D 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 table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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.

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 manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The 30D was launched at a markedly lower price (by 78 percent) than the 1D, 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

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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to isolate a subject from the 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 1D features an APS-H sensor and the Canon 30D an APS-C sensor. The sensor area in the 30D 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.

Technology-wise, the 30D uses a more advanced image processing engine (DIGIC 2) than the 1D (DIGIC), with benefits for noise reduction, color accuracy, and processing speed.

Despite having a smaller sensor, the 30D offers a higher resolution of 8.2 megapixels, compared with 4.1 MP of the 1D. 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 6.42μm versus 11.56μm for the 1D). However, it should be noted that the 30D is much more recent (by 4 years and 4 months) than the 1D, 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 30D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 30D for good quality output (200 dots per inch) amounts to 17.5 x 11.7 inch or 44.5 x 29.7 cm, for very good quality (250 dpi) 14 x 9.3 inch or 35.6 x 23.7 cm, and for excellent quality (300 dpi) 11.7 x 7.8 inch or 29.7 x 19.8 cm. The corresponding values for the Canon 1D are 12.5 x 8.3 inch or 31.7 x 21.1 cm for good quality, 10 x 6.6 inch or 25.4 x 16.9 cm for very good quality, and 8.3 x 5.5 inch 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 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 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 table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The 1D 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 1D 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. On the other hand, the viewfinder of the 30D 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 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 1D 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.

Concerning the storage of imaging data, both the 1D and the 30D 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-1D 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 1D and the 30D have been discontinued, but can regularly be found used on eBay. The 1D was replaced by the Canon 1D Mark II, while the 30D was followed by the Canon 40D. 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 how do things add up? Which of the two cameras – the Canon 1D or the Canon 30D – 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.

Advantages of the Canon EOS-1D:

• More complete view: Has a viewfinder with a larger field of view (100% vs 95%).
• Faster shutter: Has higher mechanical shutter speed (1/16000s vs 1/8000s) to freeze action.
• Faster burst: Shoots at higher frequency (8 vs 5 flaps/sec) to capture the decisive moment.
• More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
• Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
• More heavily discounted: Has been available for much longer (launched in September 2001).

Arguments in favor of the Canon EOS 30D:

• More detail: Has more megapixels (8.2 vs 4.1MP), which boosts linear resolution by 40%.
• Better jpgs: Has a more modern image processing engine (DIGIC 2 vs DIGIC).
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.56x vs 0.55x).
• Larger screen: Has a bigger rear LCD (2.5" vs 2.0") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (230k vs 120k dots).
• More compact: Is smaller (144x106mm vs 156x158mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 800g or 50 percent) and is thus easier to take along.
• Longer lasting: Gets more shots (750 versus 500) 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 (78 percent cheaper at launch).
• More modern: Reflects 4 years and 4 months of technical progress since the 1D launch.

If the number of relative strengths (bullet points above) is taken as a guide, the 30D is the clear winner of the contest (11 : 6 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 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 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 1D 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.

Expert reviews

This is why expert reviews are important. The following table reports the overall ratings of the cameras as published by some of the major 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. 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.
