Canon 10D vs T2i

The Canon EOS 10D and the Canon EOS Rebel T2i (labelled Canon 550D in some countries) are two digital cameras that were officially introduced, respectively, in February 2003 and February 2010. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The 10D has a resolution of 6.3 megapixels, whereas the T2i 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 10D and the Canon EOS Rebel T2i? 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 10D and the Canon T2i is provided 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 measures are rounded to the nearest millimeter.

Compare 10D versus T2i top
Comparison 10D or T2i rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon T2i is notably smaller (21 percent) than the Canon 10D. Moreover, the T2i is substantially lighter (38 percent) than the 10D. In this context, it is worth noting that neither the 10D nor the T2i 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 10D gets 500 shots out of its BP-511 battery, while the T2i can take 440 images on a single charge of its LP-E8 power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you would like to visualize and compare a different camera combination, just use the right or left arrows in the table to switch to the respective camera.

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 listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The T2i was launched at a markedly lower price (by 65 percent) than the 10D, 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.

 

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants 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 tend to be associated with larger, more expensive camera bodies and lenses.

Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the T2i is 3 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 T2i uses a more advanced image processing engine (DIGIC 4) than the 10D (DIGIC), with benefits for noise reduction, color accuracy, and processing speed.

Canon 10D and Canon T2i sensor measures

Despite having a slightly smaller sensor, the T2i offers a higher resolution of 17.9 megapixels, compared with 6.3 MP of the 10D. 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 7.38μm for the 10D). However, it should be noted that the T2i is much more recent (by 6 years and 11 months) than the 10D, 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 T2i implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the T2i for good quality output (200 dots per inch) amounts to 25.9 x 17.3 inch or 65.8 x 43.9 cm, for very good quality (250 dpi) 20.7 x 13.8 inch or 52.7 x 35.1 cm, and for excellent quality (300 dpi) 17.3 x 11.5 inch or 43.9 x 29.3 cm. The corresponding values for the Canon 10D are 15.4 x 10.2 inch or 39 x 26 cm for good quality, 12.3 x 8.2 inch or 31.2 x 20.8 cm for very good quality, and 10.2 x 6.8 inch or 26 x 17.3 cm for excellent quality prints.

The Canon EOS 10D has a native sensitivity range from ISO 100 to ISO 3200. The corresponding ISO settings for the Canon EOS Rebel T2i are ISO 100 to ISO 6400, with the possibility to increase the ISO range to 100-12800.

10D versus T2i 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 T2i has a markedly higher DXO score than the 10D (overall score 9 points higher), which will translate into better image quality. The advantage is based on 1 bits higher color depth, 0.6 EV in additional dynamic range, and 0.5 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras cannot only take still pictures, but also record videos. The T2i indeed provides for movie recording, while the 10D does not. The highest resolution format that the T2i can use is 1080/30p.

 

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The 10D and the T2i 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 10D has a higher magnification than the one of the T2i (0.55x vs 0.54x), 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 10D, the Canon T2i, and comparable cameras.

One feature that is present on the 10D, but is missing on the T2i 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 10D writes its imaging data to Compact Flash cards, while the T2i 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.

Studio photographers will appreciate that the Canon 10D (unlike the T2i) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the 10D and the T2i have been discontinued, but can regularly be found used on eBay. The 10D was replaced by the Canon 20D, while the T2i was followed by the Canon T3i. 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 is the bottom line? Is there a clear favorite between the Canon 10D and the Canon T2i? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.


Reasons to prefer the Canon EOS 10D:

  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.55x vs 0.54x).
  • Easier setting verification: Features an LCD display on top to control shooting parameters.
  • Longer lasting: Can take more shots (500 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 February 2003).


Arguments in favor of the Canon EOS Rebel T2i:

  • More detail: Has more megapixels (17.9 vs 6.3MP), which boosts linear resolution by 69%.
  • Better image quality: Scores markedly higher (9 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 low-light sensitivity: Can shoot in dim conditions (0.5 stops ISO advantage).
  • Better jpgs: Has a more modern image processing engine (DIGIC 4 vs DIGIC).
  • Broader imaging potential: Can capture not only stills but also 1080/30p video.
  • 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 118k dots).
  • Faster burst: Shoots at higher frequency (3.7 vs 3 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (129x98mm vs 150x107mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 320g or 38 percent) and is thus easier to take along.
  • Faster data transfer: Supports a more advanced USB protocol (2.0 vs 1.1).
  • More affordable: Was introduced into a lower priced category (65 percent cheaper at launch).
  • More modern: Reflects 6 years and 11 months of technical progress since the 10D launch.

If the count of individual advantages (bullet points above) is taken as a guide, the T2i is the clear winner of the contest (14 : 5 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision on a new camera. 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.

10D 05:14 T2i

How about other alternatives? Do the specifications of the Canon 10D and the Canon T2i 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 10D or the T2i 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 (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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
