Canon 450D vs Sony RX100 IV
The Canon EOS 450D (called Canon XSi in some regions) and the Sony Cyber-shot DSC-RX100 IV are two digital cameras that were revealed to the public, respectively, in January 2008 and June 2015. The 450D is a DSLR, while the RX100 IV is a fixed lens compact. The cameras are based on an APS-C (450D) and an one-inch (RX100 IV) sensor. The Canon has a resolution of 12.2 megapixels, whereas the Sony provides 20 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 450D and the Sony Cyber-shot DSC-RX100 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 side-by-side display below illustrates the physical size and weight of the Canon 450D and the Sony RX100 IV. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size dimensions 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 RX100 IV is considerably smaller (53 percent) than the Canon 450D. In this context, it is worth noting that neither the 450D nor the RX100 IV are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the RX100 IV has a lens built in, whereas the 450D 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 450D and their specifications in the Canon EF Lens Catalog.
Concerning battery life, the 450D gets 500 shots out of its LP-E5 battery, while the RX100 IV can take 280 images on a single charge of its NP-BX1 power pack. The power pack in the RX100 IV can be charged via the USB port, which can be very convenient when travelling.
The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

Any camera decision will obviously take relative prices into account. 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. 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 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. 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 450D features an APS-C sensor and the Sony RX100 IV an one-inch sensor. The sensor area in the RX100 IV is 65 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 2.7. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
Despite having a smaller sensor, the RX100 IV offers a higher resolution of 20 megapixels, compared with 12.2 MP of the 450D. 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 2.41μm versus 5.19μm for the 450D). However, it should be noted that the RX100 IV is much more recent (by 7 years and 4 months) than the 450D, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.
The resolution advantage of the Sony RX100 IV implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the RX100 IV for good quality output (200 dots per inch) amounts to 27.4 x 18.2 inch or 69.5 x 46.3 cm, for very good quality (250 dpi) 21.9 x 14.6 inch or 55.6 x 37.1 cm, and for excellent quality (300 dpi) 18.2 x 12.2 inch or 46.3 x 30.9 cm. The corresponding values for the Canon 450D are 21.4 x 14.2 inch or 54.3 x 36.2 cm for good quality, 17.1 x 11.4 inch or 43.4 x 28.9 cm for very good quality, and 14.2 x 9.5 inch or 36.2 x 24.1 cm for excellent quality prints.
The Canon EOS 450D has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Sony Cyber-shot DSC-RX100 IV are ISO 125 to ISO 12800, with the possibility to increase the ISO range to 80-25600.
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"). Of the two cameras under consideration, the RX100 IV has a markedly higher DXO score than the 450D (overall score 9 points higher), which will translate into better image quality. The advantage is based on 0.9 bits higher color depth, 1.8 EV in additional dynamic range, and 0.2 stops of reduced low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. The RX100 IV indeed provides for movie recording, while the 450D does not. The highest resolution format that the RX100 IV can use is 4K/30p.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the RX100 IV has an electronic viewfinder (2359k dots), while the 450D has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The viewfinder in the RX100 IV offers a wider field of view (100%) than the one in the 450D (95%), so that a larger proportion of the captured image is visible in the finder. On the other hand, the viewfinder of the 450D has a higher magnification (0.54x vs 0.22x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Canon 450D and Sony RX100 IV in connection with corresponding information for a sample of similar cameras.

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 RX100 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 450D writes its imaging data to SDHC cards, while the RX100 IV uses SDXC or Memory Stick PRO Duo cards. The RX100 IV supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the 450D 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 EOS 450D and Sony Cyber-shot DSC-RX100 IV and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 450D has a hotshoe, while the RX100 IV does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.
Both the 450D and the RX100 IV have been discontinued, but can regularly be found used on eBay. The 450D was replaced by the Canon 500D, while the RX100 IV was followed by the Sony RX100 IV. 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.
So what is the bottom line? Is there a clear favorite between the Canon 450D and the Sony RX100 IV? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

If the count of relative strengths (bullet points above) is taken as a measure, the RX100 IV is the clear winner of the contest (19 : 7 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 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 450D and the Sony RX100 IV place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Travel-Zoom 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 450D or the RX100 IV perform in practice. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.
This is why hands-on reviews by experts are important. The following table reports the overall ratings of the cameras as published by some of the major camera 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 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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
