Canon 30D vs T100

The Canon EOS 30D and the Canon EOS Rebel T100 (labelled Canon 4000D in some countries) are two digital cameras that were revealed to the public, respectively, in February 2006 and February 2018. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The 30D has a resolution of 8.2 megapixels, whereas the T100 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 30D and the Canon EOS Rebel T100? 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 30D and the Canon T100. 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.

Size Canon 30D vs Canon T100
Compare 30D versus T100 top
Comparison 30D or T100 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon T100 is notably smaller (14 percent) than the Canon 30D. Moreover, the T100 is substantially lighter (44 percent) than the 30D. In this context, it is worth noting that neither the 30D nor the T100 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 BP-511A battery, while the T100 can take 500 images on a single charge of its LP-E10 power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you want to switch the focus of the display and review another camera pair, you can 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 add-on or interchangeable lenses or optional viewfinders.

The price is, of course, an important factor in any camera decision. 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 T100 was launched at a markedly lower price (by 71 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 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. 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 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 T100 is 2 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 T100 uses a more advanced image processing engine (DIGIC 4+) than the 30D (DIGIC 2), with benefits for noise reduction, color accuracy, and processing speed.

Canon 30D and Canon T100 sensor measures

Despite having a slightly smaller sensor, the T100 offers a higher resolution of 17.9 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 4.31μm versus 6.42μm for the 30D). However, it should be noted that the T100 is much more recent (by 12 years) 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 T100 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the T100 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 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 T100 are ISO 100 to ISO 6400, with the possibility to increase the ISO range to 100-12800.

30D versus T100 MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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. Of the two cameras under consideration, the T100 has a markedly higher DXO score than the 30D (overall score 4 points higher), which will translate into better image quality. The advantage is based on 0.4 bits higher color depth, 0.6 EV in additional dynamic range, and 0.1 stops of reduced low light sensitivity. 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 T100 indeed provides for movie recording, while the 30D does not. The highest resolution format that the T100 can use is 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The 30D and the T100 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 T100 (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 following table reports on some other key feature differences and similarities of the Canon 30D, the Canon T100, and comparable cameras.

One feature that is present on the 30D, but is missing on the T100 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 T100 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 T100 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the T100 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the 30D does not provide wifi capability.

Studio photographers will appreciate that the Canon 30D (unlike the T100) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

The T100 is a recent model that features in the current product line-up of Canon. In contrast, the 30D has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the 30D was succeeded 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 what conclusions can be drawn? Which of the two cameras – the Canon 30D or the Canon T100 – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.


Reasons to prefer 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.
  • Longer lasting: Can take more shots (750 versus 500) 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 February 2006).


Arguments in favor of the Canon EOS Rebel T100:

  • More detail: Has more megapixels (17.9 vs 8.2MP), which boosts linear resolution by 48%.
  • Better image quality: Scores markedly higher (4 points) in the DXO overall evaluation.
  • More dynamic range: Captures a broader range of light and dark details (0.6 EV of extra DR).
  • Better jpgs: Has a more modern image processing engine (DIGIC 4+ vs DIGIC 2).
  • Broader imaging potential: Can capture not only stills but also 1080/30p video.
  • Larger screen: Has a bigger rear LCD (2.7" vs 2.5") for image review and settings control.
  • More compact: Is smaller (129x102mm vs 144x106mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 349g or 44 percent) and is thus easier to take along.
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • More affordable: Was introduced into a lower priced category (71 percent cheaper at launch).
  • More modern: Reflects 12 years of technical progress since the 30D launch.

If the count of individual advantages (bullet points above) is taken as a guide, the T100 is the clear winner of the contest (12 : 7 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.

30D 07:12 T100

How about other alternatives? Do the specifications of the Canon 30D and the Canon T100 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 comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the 30D or the T100. 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 adjacent summary-table relays the overall verdicts of several of the most popular 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 above review scores should be interpreted with care, 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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
