Canon XTi vs Nikon P7800
The Canon EOS Rebel XTi (called Canon 400D in some regions) and the Nikon Coolpix P7800 are two digital cameras that were officially introduced, respectively, in August 2006 and September 2013. The XTi is a DSLR, while the P7800 is a fixed lens compact. The cameras are based on an APS-C (XTi) and a 1/1.7-inch (P7800) sensor. The Canon has a resolution of 10.1 megapixels, whereas the Nikon provides 12 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 Rebel XTi and the Nikon Coolpix P7800? 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 XTi and the Nikon P7800 are illustrated in the side-by-side display below. 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 Nikon P7800 is notably smaller (13 percent) than the Canon XTi. In this context, it is worth noting that neither the XTi nor the P7800 are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the P7800 has a lens built in, whereas the XTi is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the XTi and their specifications 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, you can navigate to the CAM-parator app and make your selection from a broad list of cameras 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 P7800 was launched at a lower price than the XTi, despite having a lens built in. 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.
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. 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon XTi features an APS-C sensor and the Nikon P7800 a 1/1.7-inch sensor. The sensor area in the P7800 is 87 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 4.5. The sensor in the XTi has a native 3:2 aspect ratio, while the one in the P7800 offers a 4:3 aspect.
Despite having a smaller sensor, the P7800 offers a higher resolution of 12 megapixels, compared with 10.1 MP of the XTi. 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 1.89μm versus 5.71μm for the XTi). However, it should be noted that the P7800 is much more recent (by 7 years) than the XTi, 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 Nikon P7800 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the P7800 for good quality output (200 dots per inch) amounts to 20 x 15 inches or 50.8 x 38.1 cm, for very good quality (250 dpi) 16 x 12 inches or 40.6 x 30.5 cm, and for excellent quality (300 dpi) 13.3 x 10 inches or 33.9 x 25.4 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 Canon EOS Rebel XTi has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Nikon Coolpix P7800 are ISO 80 to ISO 3200, with the possibility to increase the ISO range to 80-6400.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 XTi has a notably higher overall DXO score than the P7800 (overall score 8 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.9 bits higher color depth, 0.7 EV of lower dynamic range, and 1.7 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.

Many modern cameras cannot only take still pictures, but also record videos. The P7800 indeed provides for movie recording, while the XTi does not. The highest resolution format that the P7800 can use is 1080/30p.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the P7800 has an electronic viewfinder (921k dots), while the XTi has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The adjacent table lists some of the other core features of the Canon XTi and Nikon P7800 along with similar information for a selection of comparators.
The Nikon P7800 has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.
The XTi writes its imaging data to Compact Flash cards, while the P7800 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 Rebel XTi and Nikon Coolpix P7800 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the XTi and the P7800 have been discontinued, but can regularly be found used on eBay. The XTi was replaced by the Canon Xsi, while the P7800 does not have a direct successor. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Nikon websites.
So how do things add up? Which of the two cameras – the Canon XTi or the Nikon P7800 – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.
Arguments in favor of the Canon EOS Rebel XTi:
- Better image quality: Scores markedly higher (8 points) in the DXO overall assessment.
- Better low-light sensitivity: Requires less light for good images (1.7 stops ISO advantage).
- Brighter framing: Features an optical viewfinder for clear, lag-free composition.
- More flexible: Can take a variety of interchangeable lenses, including specialty optics.
- More heavily discounted: Has been available for much longer (launched in August 2006).
Advantages of the Nikon Coolpix P7800:

If the number of relative strengths (bullet points above) is taken as a guide, the P7800 is the clear winner of the contest (16 : 5 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 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 technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the XTi or the P7800. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.
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], 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 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. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
