Canon 50D vs SX730
The Canon EOS 50D and the Canon PowerShot SX730 HS are two digital cameras that were announced, respectively, in August 2008 and April 2017. The 50D is a DSLR, while the SX730 is a fixed lens compact. The cameras are based on an APS-C (50D) and a 1/2.3-inch (SX730) sensor. The 50D has a resolution of 15.1 megapixels, whereas the SX730 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 50D and the Canon PowerShot SX730 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 side-by-side display below illustrates the physical size and weight of the Canon 50D and the Canon SX730. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth measures are rounded to the nearest millimeter.
The SX730 can be obtained in two different colors (black, silver), while the 50D 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 SX730 is considerably smaller (55 percent) than the Canon 50D. It is worth mentioning in this context that the 50D is splash and dust resistant, 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 50D 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 50D and their specifications in the Canon EF Lens Catalog.
Concerning battery life, the 50D gets 800 shots out of its BP-511A battery, while the SX730 can take 250 images on a single charge of its NB-13L power pack. The power pack in the SX730 can be charged via the USB port, which can be very convenient when travelling.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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 SX730 was launched at a lower price than the 50D, 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.
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. 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon 50D features an APS-C sensor and the Canon SX730 a 1/2.3-inch sensor. The sensor area in the SX730 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 50D has a native 3:2 aspect ratio, while the one in the SX730 offers a 4:3 aspect.
Technology-wise, the SX730 uses a more advanced image processing engine (DIGIC 6) than the 50D (DIGIC 4), with benefits for noise reduction, color accuracy, and processing speed.
Despite having a smaller sensor, the SX730 offers a higher resolution of 20.2 megapixels, compared with 15.1 MP of the 50D. 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 4.69μm for the 50D). However, it should be noted that the SX730 is much more recent (by 8 years and 7 months) than the 50D, 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 Canon 50D are 23.8 x 15.8 inches or 60.4 x 40.2 cm for good quality, 19 x 12.7 inches or 48.3 x 32.2 cm for very good quality, and 15.8 x 10.6 inches or 40.2 x 26.8 cm for excellent quality prints.
The Canon EOS 50D has a native sensitivity range from ISO 100 to ISO 3200, which can be extended to ISO 100-12800. The corresponding ISO settings for the Canon PowerShot SX730 HS are ISO 80 to ISO 3200 (no boost).
In terms of underlying technology, the 50D is build around a CMOS sensor, while the SX730 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 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.
|10.||Canon 7D II||APS-C||20.0||5472||3648||1080/60p||22.4||11.8||1082||70|
|Note: DXO values in italics represent estimates based on sensor size and age.|
Many modern cameras are not only capable of taking still images, but also of capturing video footage. The SX730 indeed provides for movie recording, while the 50D does not. The highest resolution format that the SX730 can use is 1080/60p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the 50D 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 table below summarizes some of the other core capabilities of the Canon 50D and Canon SX730 in connection with corresponding information for a sample of similar cameras.

One feature that is present on the 50D, 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 SX730 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 50D does not have a selfie-screen.
The 50D writes its imaging data to Compact Flash cards, while the SX730 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 50D and Canon PowerShot SX730 HS and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 50D has a hotshoe, while the SX730 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 50D (unlike the SX730) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the 50D and the SX730 have been discontinued, but can regularly be found used on ebay. The 50D was replaced by the Canon 60D, while the SX730 was followed by the Canon SX730 HS. Further information on the features and operation of the 50D and SX730 can be found, respectively, in the Canon 50D Manual (free pdf) or the online Canon SX730 Manual.
So what is the bottom line? Which of the two cameras – the Canon 50D or the Canon SX730 – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.
Advantages of the Canon EOS 50D:
- 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.

If the count of individual advantages (bullet points above) is taken as a guide, the SX730 emerges as the winner of the match-up (16 : 14 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape 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 50D and the Canon SX730 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 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 50D or the SX730. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.
This is why expert reviews are important. The following table reports the overall ratings of the cameras as published by some of the major 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.

The above review scores should be interpreted with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
