Canon D30 vs 100D

The Canon EOS-D30 and the Canon EOS 100D (labelled Canon SL1 in some countries) are two digital cameras that were officially introduced, respectively, in May 2000 and March 2013. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The D30 has a resolution of 3.1 megapixels, whereas the 100D provides 17.9 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-D30 and the Canon EOS 100D? 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 D30 and the Canon 100D. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All size dimensions are rounded to the nearest millimeter.

The 100D can be obtained in two different colors (black, white), while the D30 is only available in black.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon 100D is considerably smaller (34 percent) than the Canon D30. Moreover, the 100D is substantially lighter (46 percent) than the D30. In this context, it is worth noting that neither the D30 nor the 100D are weather-sealed.

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. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can compare the optics available in the Canon EF Lens Catalog.

Concerning battery life, the D30 gets 540 shots out of its Canon BP-511 battery, while the 100D can take 380 images on a single charge of its Canon LP-E12 power pack.

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 100D was launched at a markedly lower price (by 82 percent) than the D30, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

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 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. 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.

Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the 100D is 1 percent bigger. They nevertheless have the same format factor of 1.6. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

With 17.9MP, the 100D offers a higher resolution than the D30 (3.1MP), but the 100D has smaller individual pixels (pixel pitch of 4.31μm versus 10.29μm for the D30). Yet, the 100D is a much more recent model (by 12 years and 10 months) than the D30, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.

The resolution advantage of the Canon 100D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 100D for good quality output (200 dots per inch) amounts to 25.9 x 17.3 inches or 65.8 x 43.9 cm, for very good quality (250 dpi) 20.7 x 13.8 inches or 52.7 x 35.1 cm, and for excellent quality (300 dpi) 17.3 x 11.5 inches or 43.9 x 29.3 cm. The corresponding values for the Canon D30 are 10.8 x 7.2 inches or 27.4 x 18.3 cm for good quality, 8.6 x 5.8 inches or 21.9 x 14.6 cm for very good quality, and 7.2 x 4.8 inches or 18.3 x 12.2 cm for excellent quality prints.

The 100D has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Canon EOS-D30 has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Canon EOS 100D are ISO 100 to ISO 12800, with the possibility to increase the ISO range to 100-25600.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The 100D indeed provides for movie recording, while the D30 does not. The highest resolution format that the 100D can use is 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The D30 and the 100D 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 viewfinders of both cameras offer the same field of view (95%), as well as the same magnification (0.54x). The adjacent table lists some of the other core features of the Canon D30 and Canon 100D along with similar information for a selection of comparators.

One feature that is present on the D30, but is missing on the 100D is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.

The D30 writes its imaging data to Compact Flash cards, while the 100D uses SDXC 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-D30 and Canon EOS 100D and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Canon D30 (unlike the 100D) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the D30 and the 100D have been discontinued, but can regularly be found used on ebay. The D30 was replaced by the Canon D60, while the 100D was followed by the Canon 200D. Further information on the features and operation of the D30 and 100D can be found, respectively, in the Canon D30 Manual (free pdf) or the online Canon 100D Manual.

Review summary

So what conclusions can be drawn? Is there a clear favorite between the Canon D30 and the Canon 100D? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

Advantages of the Canon EOS-D30:

• Easier setting verification: Features an LCD display on top to control shooting parameters.
• Longer lasting: Can take more shots (540 versus 380) on a single battery charge.
• Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
• More heavily discounted: Has been available for much longer (launched in May 2000).

Arguments in favor of the Canon EOS 100D:

• More detail: Has more megapixels (17.9 vs 3.1MP), which boosts linear resolution by 140%.
• Broader imaging potential: Can capture not only stills but also 1080/30p video.
• Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
• Larger screen: Has a bigger rear LCD (3.0" vs 1.8") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (1040k vs 114k dots).
• Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
• Faster burst: Shoots at higher frequency (4.9 vs 3 flaps/sec) to capture the decisive moment.
• More compact: Is smaller (117x91mm vs 150x107mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 343g or 46 percent) and is thus easier to take along.
• Faster data transfer: Supports a more advanced USB protocol (2.0 vs 1.0).
• More affordable: Was introduced into a lower priced category (82 percent cheaper at launch).
• More modern: Reflects 12 years and 10 months of technical progress since the D30 launch.

If the count of individual advantages (bullet points above) is taken as a guide, the 100D is the clear winner of the contest (12 : 4 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 D30 and the Canon 100D 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 incomplete and does no justice, for example, to the way the D30 or the 100D perform in practice. 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 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.

The review scores listed above should be treated with care, 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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
