Canon SX730 vs T4i
The Canon PowerShot SX730 HS and the Canon EOS Rebel T4i (labelled Canon 650D in some countries) are two digital cameras that were revealed to the public, respectively, in April 2017 and June 2012. The SX730 is a fixed lens compact, while the T4i is a DSLR. The cameras are based on a 1/2.3-inch (SX730) and an APS-C (T4i) sensor. The SX730 has a resolution of 20.2 megapixels, whereas the T4i provides 17.9 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 PowerShot SX730 HS and the Canon EOS Rebel T4i? 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 SX730 and the Canon T4i. 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 SX730 can be obtained in two different colors (black, silver), while the T4i 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 T4i is considerably larger (89 percent) than the Canon SX730. In this context, it is worth noting that neither the SX730 nor the T4i are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the SX730 has a lens built in, whereas the T4i 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 T4i and their specifications in the Canon EF Lens Catalog.
Concerning battery life, the SX730 gets 250 shots out of its NB-13L battery, while the T4i can take 440 images on a single charge of its LP-E8 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 following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

Any camera decision will obviously take relative prices into account. 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 T4i, 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 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 are more costly to manufacture and tend to 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 Canon T4i an APS-C sensor. The sensor area in the T4i is 1086 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 5.6 and 1.6. The sensor in the SX730 has a native 4:3 aspect ratio, while the one in the T4i offers a 3:2 aspect.
In terms of chip-set technology, the SX730 uses a more advanced image processing engine (DIGIC 6) than the T4i (DIGIC 5), with benefits for noise reduction, color accuracy, and processing speed.
Despite having a smaller sensor, the Canon SX730 offers a higher resolution of 20.2 megapixels, compared with 17.9 MP of the Canon T4i. 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 4.31μm for the T4i). However, it should be noted that the SX730 is much more recent (by 4 years and 9 months) than the T4i, 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 T4i has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon PowerShot SX730 HS has a native sensitivity range from ISO 80 to ISO 3200. The corresponding ISO settings for the Canon EOS Rebel T4i are ISO 100 to ISO 12800, with the possibility to increase the ISO range to 100-25600.
In terms of underlying technology, the SX730 is build around a BSI-CMOS sensor, while the T4i 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.

|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 can also record movies. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the SX730 provides a higher frame rate than the T4i. It can shoot video footage at 1080/60p, while the T4i is limited to 1080/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the T4i 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 Canon T4i, and comparable cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The T4i has a touchscreen, while the SX730 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.Both cameras have an articulated rear screen that can be turned to be front-facing. This feature will be particularly appreciated by vloggers and photographers who are interested in taking selfies.
Concerning the storage of imaging data, both the SX730 and the T4i write their files to SDXC cards. The T4i supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the SX730 cannot take advantage of Ultra High Speed SD 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 PowerShot SX730 HS and Canon EOS Rebel T4i 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 T4i does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
Both the SX730 and the T4i have been discontinued, but can regularly be found used on ebay. The T4i was replaced by the Canon T5i, while the SX730 was followed by the Canon SX730 HS. Further information on the features and operation of the SX730 and T4i can be found, respectively, in the Canon SX730 Manual (free pdf) or the online Canon T4i Manual.
So what conclusions can be drawn? Is there a clear favorite between the Canon SX730 and the Canon T4i? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

- More flexible: Makes it possible to change lenses and thus to use specialty optics.
- Longer lasting: Gets more shots (440 versus 250) out of a single battery charge.
- Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
- Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
- More heavily discounted: Has been around for much longer (launched in June 2012).
If the number of relative strengths (bullet points above) is taken as a guide, the T4i emerges as the winner of the match-up (17 : 14 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 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 SX730 and the Canon T4i 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 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 SX730 or the T4i. 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 where reviews by experts come in. 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.

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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
