Canon R100 vs Sony A7R IIIA
The Canon EOS R100 and the Sony Alpha A7R IIIA are two digital cameras that were revealed to the public, respectively, in May 2023 and April 2021. Both the R100 and the A7R IIIA are mirrorless interchangeable lens cameras that are based on an APS-C (R100) and a full frame (A7R IIIA) sensor. The Canon has a resolution of 24 megapixels, whereas the Sony provides 42.2 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 R100 and the Sony Alpha A7R IIIA? 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.
Body comparison
The physical size and weight of the Canon R100 and the Sony A7R IIIA are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side 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 A7R IIIA is notably larger (22 percent) than the Canon R100. Moreover, the A7R IIIA is substantially heavier (83 percent) than the R100. It is noteworthy in this context that the A7R IIIA is splash and dust-proof, while the R100 does not feature any corresponding weather-sealing.
The above size and weight comparisons are to some extent incomplete since they do not consider the interchangeable lenses that both of these cameras require. Hence, you might want to study and compare the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.
Concerning battery life, the R100 gets 400 shots out of its Canon LP-E17 battery, while the A7R IIIA can take 650 images on a single charge of its Sony NP-FZ100 power pack. The power pack in the A7R IIIA 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 manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The R100 was launched at a markedly lower price (by 85 percent) than the A7R IIIA, which puts it into a different market segment. 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.
Sensor comparison
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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better isolate a subject from the background. On the downside, larger sensors tend to be more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon R100 features an APS-C sensor and the Sony A7R IIIA a full frame sensor. The sensor area in the A7R IIIA is 160 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
With 42.2MP, the A7R IIIA offers a higher resolution than the R100 (24MP), but the A7R IIIA nevertheless has larger individual pixels (pixel pitch of 4.52μm versus 3.72μm for the R100) due to its larger sensor. However, the R100 is a much more recent model (by 2 years and 1 month) than the A7R IIIA, and its sensor will have benefitted from technological advances during this time that 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 IIIA implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A7R IIIA for good quality output (200 dots per inch) amounts to 39.8 x 26.5 inches or 101 x 67.4 cm, for very good quality (250 dpi) 31.8 x 21.2 inches or 80.8 x 53.9 cm, and for excellent quality (300 dpi) 26.5 x 17.7 inches or 67.3 x 44.9 cm. The corresponding values for the Canon R100 are 30 x 20 inches or 76.2 x 50.8 cm for good quality, 24 x 16 inches or 61 x 40.6 cm for very good quality, and 20 x 13.3 inches or 50.8 x 33.9 cm for excellent quality prints.
Unlike the R100, the A7R IIIA has the capacity to capture high quality composite images 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 EOS R100 has a native sensitivity range from ISO 100 to ISO 25600. The corresponding ISO settings for the Sony Alpha A7R IIIA are ISO 100 to ISO 32000, with the possibility to increase the ISO range to 50-102400.
In terms of underlying technology, the R100 is build around a CMOS sensor, while the A7R IIIA 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.
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").

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 IIIA provides a faster frame rate than the R100. It can shoot movie footage at 4K/30p, while the Canon is limited to 4k/24p.
Feature comparison
Apart from body and sensor, cameras can and do differ across a variety of features. The two cameras under review are similar with respect to both having an electronic viewfinder. However, the one in the A7R IIIA offers a substantially higher resolution than the one in the R100 (3686k vs 2360k dots).

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one. |
One difference between the cameras concerns the presence of an on-board flash. The R100 has one, while the A7R IIIA does not. While the built-in flash of the R100 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, both cameras under consideration feature an 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 Canon R100 and the Sony A7R IIIA both have 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.
The R100 writes its imaging data to SDXC cards, while the A7R IIIA uses SDXC or Memory Stick PRO Duo cards. The A7R IIIA features dual card slots, which can be very useful in case a memory card fails. In contrast, the R100 only has one slot. The A7R IIIA supports UHS-II cards (on its first slot), while the R100 can use UHS-I cards.
Connectivity comparison
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 R100 and Sony Alpha A7R IIIA and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the A7R IIIA has a headphone jack, which makes it possible to attach external headphones and monitor the quality of sound during the recording process. The R100 lacks such a headphone port.
Studio photographers will appreciate that the Sony A7R IIIA (unlike the R100) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the R100 and the A7R IIIA are recent models that are part of the current product line-up. The A7R IIIA replaced the earlier Sony A7R II, while the R100 does not have a direct predecessor. Further information on the features and operation of the R100 and A7R IIIA can be found, respectively, in the Canon R100 Manual (free pdf) or the online Sony A7R IIIA Manual.
Review summary
So what conclusions can be drawn? Which of the two cameras – the Canon R100 or the Sony A7R IIIA – 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 R100:
- More compact: Is smaller (116x86mm vs 127x96mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 294g or 45 percent) and hence easier to carry around.
- Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
- More affordable: Was introduced into a lower priced category (85 percent cheaper at launch).
- More modern: Reflects 2 years and 1 month of technical progress since the A7R IIIA launch.
Reasons to prefer the Sony Alpha A7R IIIA:
- More detail: Has more megapixels (42.2 vs 24MP), which boosts linear resolution by 33%.
- High quality composites: Can combine several shots after pixel-shifting its sensor.
- 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.
- More dynamic range: Larger pixels capture a wider spectrum of light and dark details.
- Better low-light sensitivity: Larger pixels means good image quality even under poor lighting.
- Better video: Provides higher movie framerates (4K/30p versus 4k/24p).
- Better sound control: Has a headphone port that enables audio monitoring while recording.
- More detailed viewfinder: Has higher resolution electronic viewfinder (3686k vs 2360k dots).
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.78x vs 0.58x).
- More detailed LCD: Has a higher resolution rear screen (2340k vs 1040k dots).
- More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
- Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.

- More heavily discounted: Has been around for much longer (launched in April 2021).
If the count of relative strengths (bullet points above) is taken as a measure, the A7R IIIA is the clear winner of the contest (25 : 5 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 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 R100 and the Sony A7R IIIA place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera listing whether the two cameras rank among the cream of the crop.
In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the R100 or the A7R IIIA 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.
Expert reviews
This is where reviews by experts come in. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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 review scores listed above should be treated 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
