Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot SX730 HS and the Nikon D300S? 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 SX730 and the Nikon D300S 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 width, height and depth dimensions are rounded to the nearest millimeter.

The SX730 can be obtained in two different colors (black, silver), while the D300S 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 D300S is considerably larger (140 percent) than the Canon SX730. It is noteworthy in this context that the D300S is splash and dust-proof, while the SX730 does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the SX730 has a lens built in, whereas the D300S 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 D300S and their specifications in the Nikon Lens Catalog.

Concerning battery life, the SX730 gets 250 shots out of its Canon NB-13L battery, while the D300S can take 950 images on a single charge of its Nikon EN-EL3e power pack. The power pack in the SX730 can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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. The SX730 was launched at a lower price than the D300S, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

Sensor comparison

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. 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 SX730 features a 1/2.3-inch sensor and the Nikon D300S an APS-C sensor. The sensor area in the D300S 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 SX730 has a native 4:3 aspect ratio, while the one in the D300S offers a 3:2 aspect.

Despite having a smaller sensor, the Canon SX730 offers a higher resolution of 20.2 megapixels, compared with 12.2 MP of the Nikon D300S. 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 D300S). However, it should be noted that the SX730 is much more recent (by 7 years and 8 months) than the D300S, 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 SX730 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Canon SX730 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the SX730 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 D300S 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 SX730 HS has a native sensitivity range from ISO 80 to ISO 3200. The corresponding ISO settings for the Nikon D300S are ISO 200 to ISO 3200, with the possibility to increase the ISO range to 100-6400.

In terms of underlying technology, the SX730 is build around a BSI-CMOS sensor, while the D300S 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.

For many cameras, data on sensor performance has been reported by DXO Mark. 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 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 two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the SX730 provides a higher video resolution than the D300S. It can shoot video footage at 1080/60p, 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 D300S has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the SX730 relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Canon SX730, the Nikon D300S, and comparable cameras.

One feature that is present on the D300S, but is missing on the SX730 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 Nikon D300S 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 SX730 writes its imaging data to SDXC cards, while the D300S uses Compact Flash or SDXC cards. The D300S features dual card slots, which can be very useful in case a memory card fails. In contrast, the SX730 only has one slot.

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 SX730 HS and Nikon D300S and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the SX730 offers wifi support, while the D300S does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Studio photographers will appreciate that the Nikon D300S (unlike the SX730) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the SX730 and the D300S have been discontinued, but can regularly be found used on ebay. The D300S was replaced by the Nikon D500, while the SX730 was followed by the Canon SX730 HS. Further information on the features and operation of the SX730 and D300S can be found, respectively, in the Canon SX730 Manual (free pdf) or the online Nikon D300S Manual.

Review summary

So how do things add up? Is the Canon SX730 better than the Nikon D300S or vice versa? The listing below highlights the relative strengths of the two models.

Reasons to prefer the Canon PowerShot SX730 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 (1080/60p vs 720/24p).
• More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Ready to shoot: Comes with a built-in lens, while the D300S requires a separate lens.
• More compact: Is smaller (110x64mm vs 147x115mm) and thus needs less room in the bag.
• Less heavy: Is lighter even though it comes with a built-in lens (unlike the D300S).
• Easier travel charging: Can be conveniently charged via its USB port.
• 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.
• Easier wireless transfer: Supports Bluetooth for image sharing without cables.
• More affordable: Was introduced at a lower price, despite coming with a built-in lens.
• More modern: Reflects 7 years and 8 months of technical progress since the D300S launch.

Arguments in favor of the Nikon D300S:

• 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.
• Better sound: Can connect to an external microphone for higher quality sound recording.
• 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 (1/8000s vs 1/3200s) to freeze action.
• Faster burst: Shoots at higher frequency (7 vs 5.9 flaps/sec) to capture the decisive moment.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• More flexible: Makes it possible to change lenses and thus to use specialty optics.
• Longer lasting: Gets more shots (950 versus 250) out of a single battery charge.
• Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
• Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
• More heavily discounted: Has been around for much longer (launched in July 2009).

If the count of relative strengths (bullet points above) is taken as a measure, the D300S emerges as the winner of the match-up (18 : 15 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.

How about other alternatives? Do the specifications of the Canon SX730 and the Nikon D300S 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 remains incomplete and does no justice, for example, to the way the SX730 or the D300S 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.

Expert reviews

This is why hands-on reviews by experts 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 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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
