Canon 70D vs T2i
The Canon EOS 70D and the Canon EOS Rebel T2i (labelled Canon 550D in some countries) are two digital cameras that were officially introduced, respectively, in July 2013 and February 2010. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The 70D has a resolution of 20 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 70D 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.
The side-by-side display below illustrates the physical size and weight of the Canon 70D and the Canon T2i. 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.
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 (13 percent) than the Canon 70D. Moreover, the T2i is markedly lighter (30 percent) than the 70D. It is worth mentioning in this context that the 70D is splash and dust resistant, while the T2i does not feature any corresponding weather-sealing.
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. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

Any camera decision will obviously take relative prices into account. 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 42 percent) than the 70D, 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 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. 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 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 T2i 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.
In terms of chip-set technology, the 70D uses a more advanced image processing engine (DIGIC 5+) than the T2i (DIGIC 4), with benefits for noise reduction, color accuracy, and processing speed.
With 20MP, the 70D offers a higher resolution than the T2i (17.9MP), but the 70D has smaller individual pixels (pixel pitch of 4.11μm versus 4.31μm for the T2i). However, the 70D is a much more recent model (by 3 years and 4 months) than the T2i, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels.
The resolution advantage of the Canon 70D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 70D for good quality output (200 dots per inch) amounts to 27.4 x 18.2 inches or 69.5 x 46.3 cm, for very good quality (250 dpi) 21.9 x 14.6 inches or 55.6 x 37.1 cm, and for excellent quality (300 dpi) 18.2 x 12.2 inches or 46.3 x 30.9 cm. The corresponding values for the Canon T2i are 25.9 x 17.3 inches or 65.8 x 43.9 cm for good quality, 20.7 x 13.8 inches or 52.7 x 35.1 cm for very good quality, and 17.3 x 11.5 inches or 43.9 x 29.3 cm for excellent quality prints.
The 70D has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon EOS 70D has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 100-25600. 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.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.
|Canon G3 X||1-inch||20.0||5472||3648||1080/60p||21.4||12.3||521||63|
|Canon 7D II||APS-C||20.0||5472||3648||1080/60p||22.4||11.8||1082||70|
|Canon 6D||Full Frame||20.0||5472||3648||1080/30p||23.8||12.1||2340||82|
Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, and both provide the same movie specifications (1080/30p).
Apart from body and sensor, cameras can and do differ across a variety of features. The 70D 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 viewfinder in the 70D offers a wider field of view (98%) than the one in the T2i (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the 70D has a higher magnification (0.59x 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 70D, the Canon T2i, and comparable cameras.
|Canon G3 X||optional||n||3.2||1620||tilting||Y||1/2000s||5.9||Y||Y|
|Canon 7D II||optical||Y||3.0||1040||fixed||n||1/8000s||10.0||Y||n|
One feature that is present on the 70D, 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 70D has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the T2i does not have a selfie-screen.
Concerning the storage of imaging data, both the 70D and the T2i write their files to SDXC cards. The 70D supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the T2i cannot take advantage of Ultra High Speed SD 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 70D and Canon EOS Rebel T2i and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.
| WiFi |
|Canon G3 X||Y||stereo||mono||Y||Y||mini||2.0||Y||Y||-|
|Canon 7D II||Y||stereo||mono||Y||Y||mini||3.0||-||-||-|
It is notable that the 70D offers wifi support, while the T2i does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
Both the 70D and the T2i have been discontinued, but can regularly be found used on eBay. The T2i was replaced by the Canon T3i, while the 70D was followed by the Canon 80D. 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 what conclusions can be drawn? Which of the two cameras – the Canon 70D or the Canon T2i – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.

- Faster burst: Shoots at higher frequency (7 vs 3.7 flaps/sec) to capture the decisive moment.
- Longer lasting: Can take more shots (920 versus 440) on a single battery charge.
- Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
- Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
- Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
- More modern: Reflects 3 years and 4 months of technical progress since the T2i launch.
Arguments in favor of the Canon EOS Rebel T2i:
- More compact: Is smaller (129x98mm vs 139x104mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 225g or 30 percent) and is thus easier to take along.
- More affordable: Was introduced into a lower priced category (42 percent cheaper at launch).
- More heavily discounted: Has been around for much longer (launched in February 2010).
If the count of individual advantages (bullet points above) is taken as a guide, the 70D is the clear winner of the match-up (16 : 4 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 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.

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says little about, for example, the shooting experience and imaging performance of the 70D and the T2i 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 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 were established in reference to similarly priced cameras that were available in the market at the time of the review. A score, therefore, has to be seen in close connection to the price and market introduction time 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
