Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS 30D and the Canon EOS Rebel T3? 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 30D and the Canon T3 is provided 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 T3 is notably smaller (15 percent) than the Canon 30D. Moreover, the T3 is substantially lighter (37 percent) than the 30D. In this context, it is worth noting that neither the 30D nor the T3 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 30D gets 750 shots out of its Canon BP-511A battery, while the T3 can take 700 images on a single charge of its Canon LP-E10 power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The T3 was launched at a markedly lower price (by 68 percent) than the 30D, 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 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.

Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the T3 is 4 percent smaller. 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.

Technology-wise, the T3 uses a more advanced image processing engine (DIGIC 4) than the 30D (DIGIC 2), with benefits for noise reduction, color accuracy, and processing speed.

Despite having a slightly smaller sensor, the T3 offers a higher resolution of 12.2 megapixels, compared with 8.2 MP of the 30D. 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 5.15μm versus 6.42μm for the 30D). However, it should be noted that the T3 is much more recent (by 4 years and 11 months) than the 30D, 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 T3 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the T3 for good quality output (200 dots per inch) amounts to 21.4 x 14.2 inches or 54.3 x 36.2 cm, for very good quality (250 dpi) 17.1 x 11.4 inches or 43.4 x 28.9 cm, and for excellent quality (300 dpi) 14.2 x 9.5 inches or 36.2 x 24.1 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 30D has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 100-3200. The corresponding ISO settings for the Canon EOS Rebel T3 are ISO 100 to ISO 6400 (no boost).

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.

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"). The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The T3 indeed provides for movie recording, while the 30D does not. The highest resolution format that the T3 can use is 720/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The 30D and the T3 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%), but the viewfinder of the 30D has a higher magnification than the one of the T3 (0.56x vs 0.50x), 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 30D and Canon T3 along with similar information for a selection of comparators.

One feature that is present on the 30D, but is missing on the T3 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 30D writes its imaging data to Compact Flash cards, while the T3 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 30D and Canon EOS Rebel T3 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Canon 30D (unlike the T3) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the 30D and the T3 have been discontinued, but can regularly be found used on ebay. The 30D was replaced by the Canon 40D, while the T3 was followed by the Canon T5. Further information on the features and operation of the 30D and T3 can be found, respectively, in the Canon 30D Manual (free pdf) or the online Canon T3 Manual.

Review summary

So how do things add up? Is there a clear favorite between the Canon 30D and the Canon T3? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

Advantages of the Canon EOS 30D:

• Larger viewfinder image: Features a viewfinder with a higher magnification (0.56x vs 0.50x).
• Easier setting verification: Features an LCD display on top to control shooting parameters.
• Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
• Faster burst: Shoots at higher frequency (5 vs 3 flaps/sec) to capture the decisive moment.
• 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 February 2006).

Arguments in favor of the Canon EOS Rebel T3:

• More detail: Has more megapixels (12.2 vs 8.2MP), which boosts linear resolution by 22%.
• Better jpgs: Has a more modern image processing engine (DIGIC 4 vs DIGIC 2).
• Broader imaging potential: Can capture not only stills but also 720/30p video.
• Larger screen: Has a bigger rear LCD (2.7" vs 2.5") for image review and settings control.
• More compact: Is smaller (130x100mm vs 144x106mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 290g or 37 percent) and is thus easier to take along.
• More affordable: Was introduced into a lower priced category (68 percent cheaper at launch).
• More modern: Reflects 4 years and 11 months of technical progress since the 30D launch.

If the number of relative strengths (bullet points above) is taken as a guide, the T3 emerges as the winner of the match-up (8 : 6 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 30D and the Canon T3 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 30D and the T3 in practical situations. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

This is why hands-on reviews by experts are important. 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 are only valid when referring to cameras in the same category and of the same age. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, 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.
