Canon 40D vs SX740
The Canon EOS 40D and the Canon PowerShot SX740 HS are two digital cameras that were announced, respectively, in August 2007 and July 2018. The 40D is a DSLR, while the SX740 is a fixed lens compact. The cameras are based on an APS-C (40D) and a 1/2.3-inch (SX740) sensor. The 40D has a resolution of 10.1 megapixels, whereas the SX740 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 40D and the Canon PowerShot SX740 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.
The physical size and weight of the Canon 40D and the Canon SX740 are illustrated 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 width, height and depth measures are rounded to the nearest millimeter.
The SX740 can be obtained in two different colors (black, silver), while the 40D 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 SX740 is considerably smaller (55 percent) than the Canon 40D. In this context, it is worth noting that neither the 40D nor the SX740 are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the SX740 has a lens built in, whereas the 40D 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 40D and their specifications in the Canon EF Lens Catalog.

|Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.|
The price is, of course, an important factor in any camera decision. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The SX740 was launched at a lower price than the 40D, 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.
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. 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 tend to be associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Canon 40D features an APS-C sensor and the Canon SX740 a 1/2.3-inch sensor. The sensor area in the SX740 is 92 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 40D has a native 3:2 aspect ratio, while the one in the SX740 offers a 4:3 aspect.
Technology-wise, the SX740 uses a more advanced image processing engine (DIGIC 8) than the 40D (DIGIC 3), with benefits for noise reduction, color accuracy, and processing speed.
Despite having a smaller sensor, the SX740 offers a higher resolution of 20.2 megapixels, compared with 10.1 MP of the 40D. 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 5.73μm for the 40D). However, it should be noted that the SX740 is much more recent (by 10 years and 11 months) than the 40D, 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 SX740 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Canon SX740 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the SX740 for good quality output (200 dots per inch) amounts to 25.9 x 19.4 inch or 65.8 x 49.4 cm, for very good quality (250 dpi) 20.7 x 15.6 inch or 52.7 x 39.5 cm, and for excellent quality (300 dpi) 17.3 x 13 inch or 43.9 x 32.9 cm. The corresponding values for the Canon 40D are 19.4 x 13 inch or 49.4 x 32.9 cm for good quality, 15.6 x 10.4 inch or 39.5 x 26.3 cm for very good quality, and 13 x 8.6 inch or 32.9 x 21.9 cm for excellent quality prints.
The Canon EOS 40D 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 SX740 HS are ISO 100 to ISO 3200 (no boost).
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 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 SX740 indeed provides for movie recording, while the 40D does not. The highest resolution format that the SX740 can use is 4K/30p.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the 40D has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the SX740 relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Canon 40D and Canon SX740 in connection with corresponding information for a sample of similar cameras.

One feature that is present on the 40D, but is missing on the SX740 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 SX740 has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the 40D does not have a selfie-screen.
The 40D writes its imaging data to Compact Flash cards, while the SX740 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 40D and Canon PowerShot SX740 HS and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 40D has a hotshoe, while the SX740 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.
Studio photographers will appreciate that the Canon 40D (unlike the SX740) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
The SX740 is a recent model that features in the current product line-up of Canon. In contrast, the 40D has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the 40D was succeeded by the Canon 50D. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.
So what conclusions can be drawn? Is the Canon 40D better than the Canon SX740 or vice versa? The listing below highlights the relative strengths of the two models.
Reasons to prefer the Canon EOS 40D:
- 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.

If the count of individual advantages (bullet points above) is taken as a guide, the SX740 is the clear winner of the contest (17 : 13 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 40D and the Canon SX740 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 partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the 40D or the SX740. 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 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 (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
