Canon SX30 vs Sony A7R IV
The Canon PowerShot SX30 IS and the Sony Alpha A7R IV are two digital cameras that were announced, respectively, in September 2010 and July 2019. The SX30 is a fixed lens compact, while the A7R IV is a mirrorless interchangeable lens camera. The cameras are based on a 1/2.3-inch (SX30) and a full frame (A7R IV) sensor. The Canon has a resolution of 14 megapixels, whereas the Sony provides 60.2 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 PowerShot SX30 IS and the Sony Alpha A7R IV? 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 SX30 and the Sony A7R IV 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.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A7R IV is notably larger (9 percent) than the Canon SX30. It is noteworthy in this context that the A7R IV is splash and dust-proof, while the SX30 does not feature any corresponding weather-sealing.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the SX30 has a lens built in, whereas the A7R IV 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 A7R IV and their specifications in the Sony FE Lens Catalog.
The power pack in the A7R IV can be charged via the USB port, which can be very convenient when travelling.

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 SX30 was launched at a lower price than the A7R IV, 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.
The size of the sensor inside a digital camera is one of the key determinants 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 associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Canon SX30 features a 1/2.3-inch sensor and the Sony A7R IV a full frame sensor. The sensor area in the A7R IV is 2936 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 5.6 and 1.0. The sensor in the SX30 has a native 4:3 aspect ratio, while the one in the A7R IV offers a 3:2 aspect.
With 60.2MP, the A7R IV offers a higher resolution than the SX30 (14MP), but the A7R IV nevertheless has larger individual pixels (pixel pitch of 3.76μm versus 1.41μm for the SX30) due to its larger sensor. Moreover, the A7R IV is a much more recent model (by 8 years and 10 months) than the SX30, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units. 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 Sony A7R IV implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A7R IV for good quality output (200 dots per inch) amounts to 47.5 x 31.7 inches or 120.7 x 80.5 cm, for very good quality (250 dpi) 38 x 25.3 inches or 96.6 x 64.4 cm, and for excellent quality (300 dpi) 31.7 x 21.1 inches or 80.5 x 53.6 cm. The corresponding values for the Canon SX30 are 21.6 x 16.2 inches or 54.9 x 41.1 cm for good quality, 17.3 x 13 inches or 43.9 x 32.9 cm for very good quality, and 14.4 x 10.8 inches or 36.6 x 27.4 cm for excellent quality prints.
The A7R IV has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
Unlike the SX30, the A7R IV has the capacity to capture high quality composite images (241MP) by combining multiple shots after shifting its sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).
The Canon PowerShot SX30 IS has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 100-6400. The corresponding ISO settings for the Sony Alpha A7R IV are ISO 100 to ISO 32000, with the possibility to increase the ISO range to 50-102400.
For many cameras, data on sensor performance has been reported by DXO Mark. 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 following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the A7R IV provides a better video resolution than the SX30. It can shoot movie footage at 4K/30p, while the Canon is limited to 720/30p.
Beyond body and sensor, cameras can and do differ across a range of features. The two cameras under review are similar with respect to both having an electronic viewfinder. However, the one in the A7R IV offers a substantially higher resolution than the one in the SX30 (5760k vs 202k dots). The table below summarizes some of the other core capabilities of the Canon SX30 and Sony A7R IV in connection with corresponding information for a sample of similar cameras.

One difference between the cameras concerns the presence of an on-board flash. The SX30 has one, while the A7R IV does not. While the built-in flash of the SX30 is not very powerful, it can at times be useful as a fill-in light.
The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the A7R IV is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).
The Sony A7R IV 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.
Concerning the storage of imaging data, both the SX30 and the A7R IV write their files to SDXC cards. The A7R IV features dual card slots, which can be very useful in case a memory card fails. In contrast, the SX30 only has one slot. The A7R IV supports UHS-II cards (on both slots), while the SX30 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 SX30 IS and Sony Alpha A7R IV and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the A7R IV offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the SX30 does not provide wifi capability.
Studio photographers will appreciate that the Sony A7R IV (unlike the SX30) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
The A7R IV is a recent model that features in the current product line-up of Sony. In contrast, the SX30 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the SX30 was succeeded by the Canon SX40. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Sony websites.

If the count of relative strengths (bullet points above) is taken as a measure, the A7R IV is the clear winner of the contest (30 : 6 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 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 SX30 and the Sony A7R IV place the cameras among the top in their class? Find out in the latest Best Superzoom Camera and Best Mirrorless Interchangeable Lens 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 incomplete and does no justice, for example, to the way the SX30 or the A7R IV 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.
This is why expert reviews are important. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (amateurphotographer [AP], cameralabs [CL], 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 assessments were made in relation to similar cameras of the same technological generation. 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, please note that some of the review sites have changed their methodology and reporting over time.
