Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot SX1 IS and the Canon PowerShot SX430 IS? 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 SX1 and the Canon SX430 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 measures are rounded to the nearest millimeter.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon SX430 is considerably smaller (36 percent) than the Canon SX1. Moreover, the SX430 is substantially lighter (47 percent) than the SX1. In this context, it is worth noting that neither the SX1 nor the SX430 are weather-sealed.

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 SX430 was launched at a markedly lower price (by 50 percent) than the SX1, which puts it into a different market segment. 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 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. 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 associated with larger, more expensive camera bodies and lenses.

Both cameras under consideration feature a 1/2.3-inch sensor and have a format factor (sometimes also referred to as "crop factor") of 5.6. Within the spectrum of camera sensors, this places the review cameras among the smaller-sensor digicams that favor affordability and compact design. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

While the two cameras under review share the same sensor size, the SX430 offers a higher resolution of 19.9 megapixels, compared with 10 MP of the SX1. This megapixels advantage translates into a 41 percent gain in linear resolution. On the other hand, these sensor specs imply that the SX430 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 1.19μm versus 1.67μm for the SX1). However, it should be noted that the SX430 is much more recent (by 8 years and 3 months) than the SX1, and its sensor will have benefitted from technological advances during this time that compensate for the smaller pixel size. Coming back to sensor resolution, it should be mentioned that neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.

The resolution advantage of the Canon SX430 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the SX430 for good quality output (200 dots per inch) amounts to 25.8 x 19.3 inches or 65.4 x 49.1 cm, for very good quality (250 dpi) 20.6 x 15.5 inches or 52.3 x 39.3 cm, and for excellent quality (300 dpi) 17.2 x 12.9 inches or 43.6 x 32.7 cm. The corresponding values for the Canon SX1 are 18.2 x 13.7 inches or 46.3 x 34.7 cm for good quality, 14.6 x 10.9 inches or 37.1 x 27.8 cm for very good quality, and 12.2 x 9.1 inches or 30.9 x 23.2 cm for excellent quality prints.

The Canon PowerShot SX1 IS has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 100-3200. The corresponding ISO settings for the Canon PowerShot SX430 IS are ISO 100 to ISO 1600 (no boost).

In terms of underlying technology, the SX1 is build around a CMOS sensor, while the SX430 uses a CCD 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.

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"). 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 SX1 provides a higher video resolution than the SX430. It can shoot video footage at 1080/30p, while the SX430 is limited to 720/25p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the SX1 has an electronic viewfinder (202k dots), which can be very helpful when shooting in bright sunlight. In contrast, the SX430 relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Canon SX1 and Canon SX430 in connection with corresponding information for a sample of similar cameras.

Both the SX1 and the SX430 have zoom lenses built in. The SX1 has a 28-560mm f/2.8-5.7 optic and the SX430 offers a 24-1080mm f/3.5-6.6 (focal lengths in full frame equivalent terms). Hence, the SX430 provides a wider angle of view at the short end, as well as more tele-photo reach at the long end than the SX1. The SX1 offers the faster maximum aperture.

The SX1 writes its imaging data to SDHC cards, while the SX430 uses SDXC 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 SX1 IS and Canon PowerShot SX430 IS and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the SX1 has a hotshoe, while the SX430 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

Both the SX1 and the SX430 have been discontinued, but can regularly be found used on ebay. Neither of the two has a direct successor, so they represent the end of the respective camera lines from Canon. Further information on the features and operation of the SX1 and SX430 can be found, respectively, in the Canon SX1 Manual (free pdf) or the online Canon SX430 Manual.

Review summary

So what conclusions can be drawn? Which of the two cameras – the Canon SX1 or the Canon SX430 – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.

Reasons to prefer the Canon PowerShot SX1 IS:

• Better video: Provides higher definition movie capture (1080/30p vs 720/25p).
• Easier framing: Has an electronic viewfinder for image composition and settings control.
• More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
• Faster burst: Shoots at higher frequency (4 vs 0.5 flaps/sec) to capture the decisive moment.
• Better light gathering: Has a lens with a wider maximum aperture (f/2.8 vs f/3.5).
• 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 September 2008).

Advantages of the Canon PowerShot SX430 IS:

• More detail: Has more megapixels (19.9 vs 10MP), which boosts linear resolution by 41%.
• Larger screen: Has a bigger rear LCD (3.0" vs 2.8") for image review and settings control.
• Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/3200s) to freeze action.
• Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
• More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
• More compact: Is smaller (104x69mm vs 128x88mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 292g or 47 percent) and is thus easier to take along.
• 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 into a lower priced category (50 percent cheaper at launch).
• More modern: Reflects 8 years and 3 months of technical progress since the SX1 launch.

If the count of relative strengths (bullet points above) is taken as a measure, the SX430 is the clear winner of the contest (11 : 7 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 SX1 and the Canon SX430 place the cameras among the top in their class? Find out in the latest Best Superzoom Camera listing 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 partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the SX1 or the SX430. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

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.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

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. 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
