Canon D30 vs T4i
The Canon EOS-D30 and the Canon EOS Rebel T4i (labelled Canon 650D in some countries) are two digital cameras that were officially introduced, respectively, in May 2000 and June 2012. 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 T4i 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 Rebel T4i? 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 physical size and weight of the Canon D30 and the Canon T4i are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. 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 T4i is notably smaller (17 percent) than the Canon D30. Moreover, the T4i is markedly lighter (23 percent) than the D30. In this context, it is worth noting that neither the D30 nor the T4i 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.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

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 T4i was launched at a markedly lower price (by 72 percent) than the D30, which puts it into a different market segment. Usually, retail prices stay at first close to the launch price, but after several months, discounts become available. 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.
The size of the imaging sensor is a crucial determinant 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. 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 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 T4i 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 T4i offers a higher resolution than the D30 (3.1MP), but the T4i has smaller individual pixels (pixel pitch of 4.31μm versus 10.29μm for the D30). Yet, the T4i is a much more recent model (by 12 years) 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 T4i implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the T4i 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 T4i 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 Rebel T4i are ISO 100 to ISO 12800, with the possibility to increase the ISO range to 100-25600.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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"). The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.
|Note: DXO values in italics represent estimates based on sensor size and age.|
Many modern cameras cannot only take still pictures, but also record videos. The T4i indeed provides for movie recording, while the D30 does not. The highest resolution format that the T4i can use is 1080/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. The D30 and the T4i 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 D30 has a higher magnification than the one of the T4i (0.54x vs 0.53x), 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 D30 and Canon T4i along with similar information for a selection of comparators.

One feature that is present on the D30, but is missing on the T4i 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 T4i has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the D30 does not have a selfie-screen.
The D30 writes its imaging data to Compact Flash cards, while the T4i uses SDXC cards.
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 Rebel T4i 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 T4i) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the D30 and the T4i have been discontinued, but can regularly be found used on eBay. The D30 was replaced by the Canon D60, while the T4i was followed by the Canon T5i. 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 how do things add up? Which of the two cameras – the Canon D30 or the Canon T4i – 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.
Arguments in favor of the Canon EOS-D30:
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.54x vs 0.53x).
- Easier setting verification: Features an LCD display on top to control shooting parameters.
- Longer lasting: Can take more shots (540 versus 440) 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).
Advantages of the Canon EOS Rebel T4i:
- 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).
- More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
- Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- Faster burst: Shoots at higher frequency (5 vs 3 flaps/sec) to capture the decisive moment.
- More compact: Is smaller (133x100mm vs 150x107mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 175g or 23 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 (72 percent cheaper at launch).
- More modern: Reflects 12 years of technical progress since the D30 launch.
If the count of individual advantages (bullet points above) is taken as a guide, the T4i is the clear winner of the contest (14 : 5 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.

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 D30 and the T4i 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.
This is why expert reviews are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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 above review scores should be interpreted 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 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.
