Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS R5 C and the Sony Alpha A6600? 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

An illustration of the physical size and weight of the Canon R5 C and the Sony A6600 is provided in the side-by-side display below. 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.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A6600 is considerably smaller (44 percent) than the Canon R5 C. Moreover, the A6600 is substantially lighter (35 percent) than the R5 C. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.

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 R5 C gets 320 shots out of its Canon LP-E6NH battery, while the A6600 can take 810 images on a single charge of its Sony NP-FZ100 power pack. The battery packs of both cameras can be charged via USB, 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. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

Any camera decision will naturally be influenced heavily by the price. 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. The A6600 was launched at a markedly lower price (by 69 percent) than the R5 C, which puts it into a different market segment. 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

Sensor comparison

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. 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 associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Canon R5 C features a full frame sensor and the Sony A6600 an APS-C sensor. The sensor area in the A6600 is 58 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

With 44.8MP, the R5 C offers a higher resolution than the A6600 (24MP), but the R5 C nevertheless has larger individual pixels (pixel pitch of 4.39μm versus 3.91μm for the A6600) due to its larger sensor. Moreover, the R5 C is a much more recent model (by 2 years and 4 months) than the A6600, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.

The resolution advantage of the Canon R5 C implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the R5 C for good quality output (200 dots per inch) amounts to 41 x 27.3 inches or 104 x 69.4 cm, for very good quality (250 dpi) 32.8 x 21.9 inches or 83.2 x 55.5 cm, and for excellent quality (300 dpi) 27.3 x 18.2 inches or 69.4 x 46.3 cm. The corresponding values for the Sony A6600 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.

The Canon EOS R5 C has a native sensitivity range from ISO 100 to ISO 51200, which can be extended to ISO 50-102400. The corresponding ISO settings for the Sony Alpha A6600 are ISO 100 to ISO 32000, with the possibility to increase the ISO range to 100-102400.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. 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 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 are not only capable of taking still images, but can also record movies. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the R5 C provides a higher video resolution than the A6600. It can shoot video footage at 8k/60p, while the Sony is limited to 4K/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The two cameras under consideration are similar with respect to both having an electronic viewfinder. However, the one in the R5 C offers a substantially higher resolution than the one in the A6600 (5760k vs 2359k dots).

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One feature that is present on the R5 C, but is missing on the A6600 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 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 R5 C and the Sony A6600 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 R5 C writes its imaging data to CFexpress (type B) or SDXC cards, while the A6600 uses SDXC or Memory Stick PRO Duo cards. The R5 C features dual card slots, which can be very useful in case a memory card fails. In contrast, the A6600 only has one slot. The R5 C supports UHS-II cards (on both slots), while the A6600 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 R5 C and Sony Alpha A6600 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Canon R5 C (unlike the A6600) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the R5 C and the A6600 are recent models that are part of the current product line-up. The A6600 replaced the earlier Sony A6500, while the R5 C does not have a direct predecessor. Further information on the features and operation of the R5 C and A6600 can be found, respectively, in the Canon R5 C Manual (free pdf) or the online Sony A6600 Manual.

Review summary

So what is the bottom line? Is the Canon R5 C better than the Sony A6600 or vice versa? A synthesis of the relative strong points of each of the models is listed below.

Reasons to prefer the Canon EOS R5 C:

• More detail: Offers more megapixels (44.8 vs 24MP) with a 37% higher linear resolution.
• Better image quality: Features a larger and more technologically advanced imaging sensor.
• Richer colors: The sensor size advantage translates into images with better, more accurate colors.
• More dynamic range: Larger sensor captures a wider spectrum of light and dark details.
• Better low-light sensitivity: Larger sensor produces good images even in poorly lit environments.
• Better video: Provides higher definition movie capture (8k/60p vs 4K/30p).
• More detailed viewfinder: Has higher resolution electronic viewfinder (5760k vs 2359k dots).
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.76x vs 0.70x).
• Easier setting verification: Features an LCD display on top to control shooting parameters.
• Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (2100k vs 922k dots).
• More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
• Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
• Faster data transfer: Supports a more advanced USB protocol (3.2 vs 2.0).
• Better studio light control: Has a PC Sync socket to connect to professional strobe lights.

• Faster buffer clearing: Supports a more advanced SD data transfer standard (UHS-II vs UHS-I).
• More modern: Reflects 2 years and 4 months of technical progress since the A6600 launch.

Arguments in favor of the Sony Alpha A6600:

• More compact: Is smaller (120x67mm vs 142x101mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 267g or 35 percent) and is thus easier to take along.
• Longer lasting: Gets more shots (810 versus 320) out of a single battery charge.
• Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• More affordable: Was introduced into a lower priced category (69 percent cheaper at launch).
• More heavily discounted: Has been around for much longer (launched in August 2019).

If the number of relative strengths (bullet points above) is taken as a guide, the R5 C is the clear winner of the match-up (18 : 7 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 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 R5 C and the Sony A6600 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 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 R5 C or the A6600. 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 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], 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 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 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.
