Canon XTi vs Nikon Coolpix A
The Canon EOS Rebel XTi (called Canon 400D in some regions) and the Nikon Coolpix A are two digital cameras that were revealed to the public, respectively, in August 2006 and March 2013. The XTi is a DSLR, while the Coolpix A is a fixed lens compact. Both cameras are equipped with an APS-C sensor. The Canon has a resolution of 10.1 megapixels, whereas the Nikon provides 16.1 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 Rebel XTi and the Nikon Coolpix A? 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 XTi and the Nikon Coolpix A. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter.
The Coolpix A can be obtained in two different colors (black, silver), while the XTi is only available in black.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon Coolpix A is considerably smaller (33 percent) than the Canon XTi. In this context, it is worth noting that neither the XTi nor the Coolpix A are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the Coolpix A 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 following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

The price is, of course, an important factor in any camera decision. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. 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 size of the sensor inside a digital camera is one of the key determinants 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. 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 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 Coolpix A is 12 percent bigger. As a result of these sensor size differences, the cameras have format factors, respectively, of 1.6 (XTi) and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
With 16.1MP, the Coolpix A offers a higher resolution than the XTi (10.1MP), but the Coolpix A has smaller individual pixels (pixel pitch of 4.78μm versus 5.71μm for the XTi). Yet, the Coolpix A is a much more recent model (by 6 years and 6 months) than the XTi, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the Coolpix A has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Nikon Coolpix A implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the Coolpix A for good quality output (200 dots per inch) amounts to 24.6 x 16.3 inches or 62.6 x 41.5 cm, for very good quality (250 dpi) 19.7 x 13.1 inches or 50.1 x 33.2 cm, and for excellent quality (300 dpi) 16.4 x 10.9 inches or 41.7 x 27.6 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 A are ISO 100 to ISO 6400, with the possibility to increase the ISO range to 100-25600.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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"). Of the two cameras under consideration, the Coolpix A offers substantially better image quality than the XTi (overall score 18 points higher). The advantage is based on 1.3 bits higher color depth, 2.8 EV in additional dynamic range, and 0.8 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.
|2.||Nikon Coolpix A||APS-C||16.1||4928||3264||1080/30p||23.4||13.8||1164||80|
|Note: DXO values in italics represent estimates based on sensor size and age.|
Many modern cameras cannot only take still pictures, but also record videos. The Coolpix A indeed provides for movie recording, while the XTi does not. The highest resolution format that the Coolpix A can use is 1080/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the XTi has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the Coolpix A relies on live view and the rear LCD for framing. That said, the Coolpix A can be equipped with an optional viewfinder – the DF-CP1. The adjacent table lists some of the other core features of the Canon XTi and Nikon Coolpix A along with similar information for a selection of comparators.

The Nikon Coolpix A 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 Coolpix A 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 A and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the XTi and the Coolpix A have been discontinued, but can regularly be found used on eBay. The XTi was replaced by the Canon Xsi, while the Coolpix A 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 what is the bottom line? Is the Canon XTi better than the Nikon Coolpix A or vice versa? The listing below highlights the relative strengths of the two models.
Advantages of the Canon EOS Rebel XTi:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Easier framing: Has an optical viewfinder for image composition and settings control.
- Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
- More flexible: Can take a variety of interchangeable lenses, including specialty optics.
- Longer lasting: Can take more shots (370 versus 230) on a single battery charge.
- More heavily discounted: Has been available for much longer (launched in August 2006).
Arguments in favor of the Nikon Coolpix A:
- More detail: Has more megapixels (16.1 vs 10.1MP), which boosts linear resolution by 26%.
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Better image quality: Scores substantially higher (18 points) in the DXO overall evaluation.
- Richer colors: Generates noticeably more natural colors (1.3 bits more color depth).
- More dynamic range: Captures a broader range of light and dark details (2.8 EV of extra DR).
- Better low-light sensitivity: Can shoot in dim conditions (0.8 stops ISO advantage).
- Broader imaging potential: Can capture not only stills but also 1080/30p video.
- Larger screen: Has a bigger rear LCD (3.0" vs 2.5") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (921k vs 230k dots).
- Faster burst: Shoots at higher frequency (4 vs 3 flaps/sec) to capture the decisive moment.
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- Ready to shoot: Comes with an integrated lens, while the XTi requires a separate lens.
- More compact: Is smaller (111x64mm vs 127x84mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight even though it has a lens built in (unlike the XTi).
- More modern: Reflects 6 years and 6 months of technical progress since the XTi launch.
If the count of relative strengths (bullet points above) is taken as a measure, the Coolpix A is the clear winner of the contest (15 : 6 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.
How about other alternatives? Do the specifications of the Canon XTi and the Nikon Coolpix A place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Prime Lens Compact Camera listings 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 says little about, for example, the shooting experience and imaging performance of the XTi and the Coolpix A 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 why expert reviews are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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.

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
