Canon 450D vs SX610

The Canon EOS 450D (called Canon XSi in some regions) and the Canon PowerShot SX610 HS are two digital cameras that were revealed to the public, respectively, in January 2008 and January 2015. The 450D is a DSLR, while the SX610 is a fixed lens compact. The cameras are based on an APS-C (450D) and a 1/2.3-inch (SX610) sensor. The 450D has a resolution of 12.2 megapixels, whereas the SX610 provides 20.2 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 450D and the Canon PowerShot SX610 HS? 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

An illustration of the physical size and weight of the Canon 450D and the Canon SX610 is provided in the side-by-side display below. 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 SX610 can be obtained in three different colors (black, red, white), while the 450D 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 Canon SX610 is considerably smaller (49 percent) than the Canon 450D. In this context, it is worth noting that neither the 450D nor the SX610 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 450D 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 450D and their specifications in the Canon EF Lens Catalog.

Concerning battery life, the 450D gets 500 shots out of its Canon LP-E5 battery, while the SX610 can take 270 images on a single charge of its Canon NB-6LH power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

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. The SX610 was launched at a lower price than the 450D, despite having a lens built in. 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.

Sensor comparison

The size of the imaging sensor is a crucial determinant 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon 450D features an APS-C sensor and the Canon SX610 a 1/2.3-inch sensor. The sensor area in the SX610 is 91 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 5.6. The sensor in the 450D has a native 3:2 aspect ratio, while the one in the SX610 offers a 4:3 aspect.

Technology-wise, the SX610 uses a more advanced image processing engine (DIGIC 4+) than the 450D (DIGIC 3), with benefits for noise reduction, color accuracy, and processing speed.

Despite having a smaller sensor, the SX610 offers a higher resolution of 20.2 megapixels, compared with 12.2 MP of the 450D. 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 5.19μm for the 450D). However, it should be noted that the SX610 is much more recent (by 6 years and 11 months) than the 450D, 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 Canon 450D 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 450D has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Canon PowerShot SX610 HS are ISO 80 to ISO 3200 (no boost).

In terms of underlying technology, the 450D is build around a CMOS sensor, while the SX610 uses a BSI-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 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"). The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras cannot only take still pictures, but also record videos. The SX610 indeed provides for movie recording, while the 450D does not. The highest resolution format that the SX610 can use is 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the 450D 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 table below summarizes some of the other core capabilities of the Canon 450D and Canon SX610 in connection with corresponding information for a sample of similar cameras.

It is notable that the 450D has a hotshoe, while the SX610 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

Both the 450D and the SX610 have been discontinued, but can regularly be found used on ebay. The 450D was replaced by the Canon 500D, while the SX610 was followed by the Canon SX620. Further information on the features and operation of the 450D and SX610 can be found, respectively, in the Canon 450D Manual (free pdf) or the online Canon SX610 Manual.

Review summary

So what is the bottom line? Is there a clear favorite between the Canon 450D and the Canon SX610? Which camera is better? The listing below highlights the relative strengths of the two models.

Advantages of the Canon EOS 450D:

• 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.
• Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
• Faster burst: Shoots at higher frequency (3.5 vs 2.5 flaps/sec) to capture the decisive moment.
• More flexible: Can take a variety of interchangeable lenses, including specialty optics.
• Longer lasting: Can take more shots (500 versus 270) on a single battery charge.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• More heavily discounted: Has been available for much longer (launched in January 2008).

Reasons to prefer the Canon PowerShot SX610 HS:

• More detail: Has more megapixels (20.2 vs 12.2MP), which boosts linear resolution by 26%.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Better jpgs: Has a more modern image processing engine (DIGIC 4+ vs DIGIC 3).
• Broader imaging potential: Can capture not only stills but also 1080/30p video.
• More detailed LCD: Has a higher resolution rear screen (922k vs 230k dots).
• Ready to shoot: Comes with an integrated lens, while the 450D requires a separate lens.
• More compact: Is smaller (105x61mm 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 450D).
• Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
• 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 11 months of technical progress since the 450D launch.

If the count of individual advantages (bullet points above) is taken as a guide, the SX610 comes out slightly ahead of the 450D (13 : 12 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.

How about other alternatives? Do the specifications of the Canon 450D and the Canon SX610 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Superzoom 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 remains incomplete and does no justice, for example, to the way the 450D or the SX610 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.

Expert reviews

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.

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 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.
