Canon XSi vs Nikon Coolpix A
The Canon EOS Rebel XSi (called Canon 450D in some regions) and the Nikon Coolpix A are two digital cameras that were officially introduced, respectively, in January 2008 and March 2013. The XSi 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 12.2 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 XSi 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.
An illustration of the physical size and weight of the Canon XSi and the Nikon Coolpix A is provided 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 size dimensions are rounded to the nearest millimeter.
The Coolpix A can be obtained in two different colors (black, silver), while the XSi 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 (44 percent) than the Canon XSi. In this context, it is worth noting that neither the XSi 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 XSi 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 XSi and their specifications in the Canon EF Lens Catalog.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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 naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. 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.
The size of the imaging sensor is a crucial determinant 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. 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 Coolpix A is 12 percent bigger. As a result of these sensor size differences, the cameras have format factors, respectively, of 1.6 (XSi) 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 XSi (12.2MP), but the Coolpix A has smaller individual pixels (pixel pitch of 4.78μm versus 5.19μm for the XSi). Yet, the Coolpix A is a much more recent model (by 5 years and 1 month) than the XSi, 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 XSi are 21.4 x 14.2 inches or 54.3 x 36.2 cm for good quality, 17.1 x 11.4 inches or 43.4 x 28.9 cm for very good quality, and 14.2 x 9.5 inches or 36.2 x 24.1 cm for excellent quality prints.
The Canon EOS Rebel XSi 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.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). Of the two cameras under consideration, the Coolpix A offers substantially better image quality than the XSi (overall score 19 points higher). The advantage is based on 1.5 bits higher color depth, 3 EV in additional dynamic range, and 0.8 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 are not only capable of taking still images, but also of capturing video footage. The Coolpix A indeed provides for movie recording, while the XSi does not. The highest resolution format that the Coolpix A can use is 1080/30p.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the XSi 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 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 XSi writes its imaging data to SDHC 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 XSi and Nikon Coolpix A and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the XSi and the Coolpix A have been discontinued, but can regularly be found used on eBay. The XSi was replaced by the Canon T1i, 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 conclusions can be drawn? Is there a clear favorite between the Canon XSi and the Nikon Coolpix A? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.
Advantages of the Canon EOS Rebel XSi:
- 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 (500 versus 230) on a single battery charge.
- More heavily discounted: Has been available for much longer (launched in January 2008).
Arguments in favor of the Nikon Coolpix A:
- More detail: Has more megapixels (16.1 vs 12.2MP), which boosts linear resolution by 15%.
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Better image quality: Scores substantially higher (19 points) in the DXO overall evaluation.
- Richer colors: Generates noticeably more natural colors (1.5 bits more color depth).
- More dynamic range: Captures a broader range of light and dark details (3 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.
- More detailed LCD: Has a higher resolution rear screen (921k vs 230k dots).
- Faster burst: Shoots at higher frequency (4 vs 3.5 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 XSi requires a separate lens.
- More compact: Is smaller (111x64mm vs 129x98mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight even though it has a lens built in (unlike the XSi).
- More modern: Reflects 5 years and 1 month of technical progress since the XSi launch.
If the number of relative strengths (bullet points above) is taken as a guide, the Coolpix A is the clear winner of the contest (14 : 6 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 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.
How about other alternatives? Do the specifications of the Canon XSi 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 technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the XSi or the Coolpix A perform in practice. 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 where reviews by experts come in. The adjacent summary-table relays the overall verdicts of several of the most popular camera 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.

The above review scores should be interpreted with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. A score, therefore, has to be seen in close connection to the price and market introduction time 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.
