Canon 70D vs XTi
The Canon EOS 70D and the Canon EOS Rebel XTi (labelled Canon 400D in some countries) are two digital cameras that were revealed to the public, respectively, in July 2013 and August 2006. 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 XTi provides 10.1 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 XTi? 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 XTi. 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 XTi is notably smaller (26 percent) than the Canon 70D. Moreover, the XTi is markedly lighter (26 percent) than the 70D. It is worth mentioning in this context that the 70D is splash and dust resistant, while the XTi 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 adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. 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.

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 XTi was launched at a markedly lower price (by 33 percent) than the 70D, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
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 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 XTi 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.
In terms of chip-set technology, the 70D uses a more advanced image processing engine (DIGIC 5+) than the XTi (DIGIC II), with benefits for noise reduction, color accuracy, and processing speed.
With 20MP, the 70D offers a higher resolution than the XTi (10.1MP), but the 70D has smaller individual pixels (pixel pitch of 4.11μm versus 5.71μm for the XTi). However, the 70D is a much more recent model (by 6 years and 10 months) than the XTi, 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 XTi are 19.4 x 13 inches or 49.4 x 32.9 cm for good quality, 15.6 x 10.4 inches or 39.5 x 26.3 cm for very good quality, and 13 x 8.6 inches or 32.9 x 21.9 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 XTi are ISO 100 to ISO 1600 (no boost).
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 review, the 70D has a notably higher overall DXO score than the XTi (overall score 6 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.4 bits higher color depth, 0.6 EV in additional dynamic range, and 0.5 stops in additional 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.
|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 also of capturing video footage. The 70D indeed provides movie recording capabilities, while the XTi does not. The highest resolution format that the 70D can use is 1080/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. The 70D and the XTi 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 XTi (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 0.49x), 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 XTi, and comparable cameras.

One feature that is present on the 70D, but is missing on the XTi 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 XTi does not have a selfie-screen.
The 70D writes its imaging data to SDXC cards, while the XTi uses Compact Flash 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 XTi 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 XTi does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
Both the 70D and the XTi have been discontinued, but can regularly be found used on eBay. The XTi was replaced by the Canon Xsi, 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 XTi – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.

- More modern: Reflects 6 years and 10 months of technical progress since the XTi launch.
Arguments in favor of the Canon EOS Rebel XTi:
- More compact: Is smaller (127x84mm vs 139x104mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 199g or 26 percent) and is thus easier to take along.
- More affordable: Was introduced into a lower priced category (33 percent cheaper at launch).
- More heavily discounted: Has been around for much longer (launched in August 2006).
If the count of individual advantages (bullet points above) is taken as a guide, the 70D is the clear winner of the match-up (21 : 4 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 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 the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the 70D or the XTi 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.
This is why expert reviews are important. The adjacent summary-table relays the overall verdicts of several of the most popular 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 above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. 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, please note that some of the review sites have changed their methodology and reporting over time.
