Sony RX100 IV vs Canon 77D

The Sony Cyber-shot DSC-RX100 IV and the Canon EOS 77D are two digital cameras that were revealed to the public, respectively, in June 2015 and February 2017. The RX100 IV is a fixed lens compact, while the 77D is a DSLR. The cameras are based on an one-inch (RX100 IV) and an APS-C (77D) sensor. The Sony has a resolution of 20 megapixels, whereas the Canon provides 24 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 Sony Cyber-shot DSC-RX100 IV and the Canon EOS 77D? 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 Sony RX100 IV and the Canon 77D 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 size dimensions are rounded to the nearest millimeter.

Compare RX100 IV versus 77D top
Comparison RX100 IV or 77D rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon 77D is considerably larger (121 percent) than the Sony RX100 IV. In this context, it is worth noting that neither the RX100 IV nor the 77D 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 77D 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 77D and their specifications in the Canon EF Lens Catalog.

Concerning battery life, the RX100 IV gets 280 shots out of its NP-BX1 battery, while the 77D can take 600 images on a single charge of its LP-E17 power pack. The power pack in the RX100 IV can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. 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 imaging sensor is a crucial determinant 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. 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Sony RX100 IV features an one-inch sensor and the Canon 77D an APS-C sensor. The sensor area in the 77D is 186 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 1.6. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Sony RX100 IV and Canon 77D sensor measures

With 24MP, the 77D offers a higher resolution than the RX100 IV (20MP), but the 77D nevertheless has larger individual pixels (pixel pitch of 3.72μm versus 2.41μm for the RX100 IV) due to its larger sensor. Moreover, the 77D is a somewhat more recent model (by 1 year and 8 months) than the RX100 IV, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.

The resolution advantage of the Canon 77D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 77D for good quality output (200 dots per inch) amounts to 30 x 20 inch or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inch or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inch or 50.8 x 33.9 cm. The corresponding values for the Sony RX100 IV are 27.4 x 18.2 inch or 69.5 x 46.3 cm for good quality, 21.9 x 14.6 inch or 55.6 x 37.1 cm for very good quality, and 18.2 x 12.2 inch or 46.3 x 30.9 cm for excellent quality prints.

The 77D has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Sony Cyber-shot DSC-RX100 IV has a native sensitivity range from ISO 125 to ISO 12800, which can be extended to ISO 80-25600. The corresponding ISO settings for the Canon EOS 77D are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 100-51200.

RX100 IV versus 77D MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 77D has a markedly higher DXO score than the RX100 IV (overall score 8 points higher), which will translate into better image quality. The advantage is based on 0.8 bits higher color depth, 0.7 EV in additional dynamic range, and 0.7 stops in additional low light sensitivity. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the RX100 IV provides a higher video resolution than the 77D. It can shoot video footage at 4K/30p, while the Canon is limited to 1080/60p.

 

Feature comparison

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 77D 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 77D (95%), so that a larger proportion of the captured image is visible in the finder. On the other hand, the viewfinder of the 77D has a higher magnification (0.51x vs 0.22x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The adjacent table lists some of the other core features of the Sony RX100 IV and Canon 77D along with similar information for a selection of comparators.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The 77D has a touchscreen, while the RX100 IV 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.

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 Canon 77D 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.

The RX100 IV writes its imaging data to SDXC or Memory Stick PRO Duo cards, while the 77D uses SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.

 

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 Sony Cyber-shot DSC-RX100 IV and Canon EOS 77D and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 77D has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The RX100 IV does not feature such a mic input.

The 77D is a recent model that features in the current product line-up of Canon. In contrast, the RX100 IV has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the RX100 IV was succeeded 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 Sony and Canon websites.


Review summary

So how do things add up? Which of the two cameras – the Sony RX100 IV or the Canon 77D – 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.

ilogo

Arguments in favor of the Sony Cyber-shot DSC-RX100 IV:

  • Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
  • More framing info: Has an electronic viewfinder that displays shooting data.
  • More complete view: Has a viewfinder with a larger field of view (100% vs 95%).
  • More detailed LCD: Has a higher resolution rear screen (1228k vs 1040k dots).
  • Faster burst: Shoots at higher frequency (16 vs 6 flaps/sec) to capture the decisive moment.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • Ready to shoot: Comes with a built-in lens, while the 77D requires a separate lens.
  • More compact: Is smaller (102x58mm vs 131x100mm) and thus needs less room in the bag.
  • Less heavy: Is lighter even though it comes with a built-in lens (unlike the 77D).
  • Easier travel charging: Can be conveniently charged via its USB port.
  • Sharper images: Has hand-shake reducing image stabilization built-in.
  • More heavily discounted: Has been on the market for longer (launched in June 2015).

ilogo

Advantages of the Canon EOS 77D:

  • More detail: Has more megapixels (24 vs 20MP), which boosts linear resolution by 10%.
  • Better image quality: Scores markedly higher (8 points) in the DXO overall evaluation.
  • More dynamic range: Captures a broader range of light and dark details (0.7 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (0.7 stops ISO advantage).
  • Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
  • Better sound: Can connect to an external microphone for higher quality sound recording.
  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.51x vs 0.22x).
  • Easier setting verification: Features a control panel on top to check shooting parameters.
  • More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • More flexible: Makes it possible to change lenses and thus to use specialty optics.
  • Longer lasting: Gets more shots (600 versus 280) out of a single battery charge.
  • Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
  • Easier wireless transfer: Supports Bluetooth for image sharing without cables.
  • More modern: Was introduced somewhat (1 year and 8 months) more recently.

If the number of relative strengths (bullet points above) is taken as a guide, the 77D is the clear winner of the contest (18 : 11 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 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.

RX100 IV 11:18 77D

How about other alternatives? Do the specifications of the Sony RX100 IV and the Canon 77D place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera and Best DSLR Camera listings 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 says little about, for example, the shooting experience and imaging performance of the RX100 IV and the 77D in practical situations. 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 (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.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (-) not available.

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.
