Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot SX610 HS and the Nikon D90? 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.

Body comparison

The physical size and weight of the Canon SX610 and the Nikon D90 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.

The SX610 can be obtained in three different colors (black, red, white), while the D90 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 D90 is considerably larger (112 percent) than the Canon SX610. In this context, it is worth noting that neither the SX610 nor the D90 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the SX610 has a lens built in, whereas the D90 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 D90 and their specifications in the Nikon Lens Catalog.

Concerning battery life, the SX610 gets 270 shots out of its Canon NB-6LH battery, while the D90 can take 850 images on a single charge of its Nikon EN-EL3e power pack.

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, you can move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The SX610 was launched at a lower price than the D90, 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.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixels 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon SX610 features a 1/2.3-inch sensor and the Nikon D90 an APS-C sensor. The sensor area in the D90 is 1232 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 5.6 and 1.5. The sensor in the SX610 has a native 4:3 aspect ratio, while the one in the D90 offers a 3:2 aspect.

Despite having a smaller sensor, the Canon SX610 offers a higher resolution of 20.2 megapixels, compared with 12.2 MP of the Nikon D90. 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 1.18μm versus 5.53μm for the D90). However, it should be noted that the SX610 is much more recent (by 6 years and 4 months) than the D90, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently. Coming back to sensor resolution, it should be mentioned that the SX610 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Canon SX610 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the SX610 for good quality output (200 dots per inch) amounts to 25.9 x 19.4 inches or 65.8 x 49.4 cm, for very good quality (250 dpi) 20.7 x 15.6 inches or 52.7 x 39.5 cm, and for excellent quality (300 dpi) 17.3 x 13 inches or 43.9 x 32.9 cm. The corresponding values for the Nikon D90 are 21.4 x 14.2 inches or 54.5 x 36.2 cm for good quality, 17.2 x 11.4 inches or 43.6 x 28.9 cm for very good quality, and 14.3 x 9.5 inches or 36.3 x 24.1 cm for excellent quality prints.

The Canon PowerShot SX610 HS has a native sensitivity range from ISO 80 to ISO 3200. The corresponding ISO settings for the Nikon D90 are ISO 200 to ISO 3200, with the possibility to increase the ISO range to 200-6400.

In terms of underlying technology, the SX610 is build around a BSI-CMOS sensor, while the D90 uses a CMOS imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

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. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the SX610 provides a higher video resolution than the D90. It can shoot video footage at 1080/30p, while the Nikon is limited to 720/24p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the D90 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the SX610 relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Canon SX610 and Nikon D90 along with similar information for a selection of comparators.

One feature that is present on the D90, but is missing on the SX610 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 SX610 writes its imaging data to SDXC cards, while the D90 uses SDHC cards.

Connectivity comparison

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 PowerShot SX610 HS and Nikon D90 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the SX610 offers wifi support, while the D90 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Both the SX610 and the D90 have been discontinued, but can regularly be found used on ebay. The D90 was replaced by the Nikon D7000, while the SX610 was followed by the Canon SX620. Further information on the features and operation of the SX610 and D90 can be found, respectively, in the Canon SX610 Manual (free pdf) or the online Nikon D90 Manual.

Review summary

So what is the bottom line? Is the Canon SX610 better than the Nikon D90 or vice versa? Below is a summary of the relative strengths of each of the two contestants.

Advantages of the Canon PowerShot SX610 HS:

• More detail: Offers more megapixels (20.2 vs 12.2MP) with a 26% higher linear resolution.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Better video: Provides higher definition movie capture (1080/30p vs 720/24p).
• Ready to shoot: Comes with a built-in lens, while the D90 requires a separate lens.
• More compact: Is smaller (105x61mm vs 132x103mm) and thus needs less room in the bag.
• Less heavy: Is lighter even though it comes with a built-in lens (unlike the D90).
• Sharper images: Has hand-shake reducing image stabilization built-in.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• More affordable: Was introduced at a lower price, despite coming with a built-in lens.
• More modern: Reflects 6 years and 4 months of technical progress since the D90 launch.

Arguments in favor of the Nikon D90:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
• Richer colors: The pixel size advantage translates into images with better, more accurate colors.
• More dynamic range: Larger pixels capture a wider spectrum of light and dark details.
• Better low-light sensitivity: Larger pixels means good image quality even under poor lighting.
• Easier framing: Has an optical viewfinder for image composition and settings control.
• Easier setting verification: Features a control panel on top to check shooting parameters.
• Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
• Faster burst: Shoots at higher frequency (4.5 vs 2.5 flaps/sec) to capture the decisive moment.
• More flexible: Makes it possible to change lenses and thus to use specialty optics.
• Longer lasting: Gets more shots (850 versus 270) out of a single battery charge.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• More heavily discounted: Has been around for much longer (launched in August 2008).

If the count of individual advantages (bullet points above) is taken as a guide, the D90 emerges as the winner of the match-up (13 : 11 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 SX610 and the Nikon D90 place the cameras among the top in their class? Find out in the latest Best Superzoom Camera and Best DSLR Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it says little about, for example, the shooting experience and imaging performance of the SX610 and the D90 in practical situations. 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.

Expert reviews

This is why hands-on reviews by experts are important. 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.

Care should be taken when interpreting the review scores above, 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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
