Canon G9 X Mark II vs Epson R-D1
The Canon PowerShot G9 X Mark II and the Epson R-D1 are two digital cameras that were announced, respectively, in January 2017 and March 2004. The G9X Mark II is a fixed lens compact, while the R-D1 is a rangefinder-style mirrorless. The cameras are based on an one-inch (G9X Mark II) and an APS-C (R-D1) sensor. The Canon has a resolution of 20 megapixels, whereas the Epson provides 6 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 G9 X Mark II and the Epson R-D1? 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.
An illustration of the physical size and weight of the Canon G9 X Mark II and the Epson R-D1 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 dimensions are rounded to the nearest millimeter.
The G9X Mark II can be obtained in two different colors (black, silver), while the R-D1 is only available in black.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Epson R-D1 is considerably larger (122 percent) than the Canon G9 X Mark II. In this context, it is worth noting that neither the G9X Mark II nor the R-D1 are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G9X Mark II has a lens built in, whereas the R-D1 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 R-D1 and their specifications in the Leica M Lens Catalog.
The power pack in the G9X Mark II can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

Any camera decision will naturally be influenced heavily by the price. 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 G9X Mark II was launched at a lower price than the R-D1, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon G9 X Mark II features an one-inch sensor and the Epson R-D1 an APS-C sensor. The sensor area in the R-D1 is 219 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
Despite having a smaller sensor, the Canon G9 X Mark II offers a higher resolution of 20 megapixels, compared with 6 MP of the Epson R-D1. 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 7.85μm for the R-D1). However, it should be noted that the G9X Mark II is much more recent (by 12 years and 9 months) than the R-D1, 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 Canon G9 X Mark II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G9X Mark II 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 Epson R-D1 are 15 x 10 inch or 38.2 x 25.4 cm for good quality, 12 x 8 inch or 30.6 x 20.3 cm for very good quality, and 10 x 6.7 inch or 25.5 x 16.9 cm for excellent quality prints.
The Canon PowerShot G9 X Mark II has a native sensitivity range from ISO 125 to ISO 12800. The corresponding ISO settings for the Epson R-D1 are ISO 200 to ISO 1600 (no boost).
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"). 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 G9X Mark II indeed provides movie recording capabilities, while the R-D1 does not. The highest resolution format that the G9X Mark II can use is 1080/60p.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the R-D1 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the G9X Mark II relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Canon G9 X Mark II, the Epson R-D1, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The G9X Mark II has one, while the R-D1 does not. While the built-in flash of the G9X Mark II is not very powerful, it can at times be useful as a fill-in light.
The Canon G9 X Mark II 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 G9X Mark II writes its imaging data to SDXC cards, while the R-D1 uses SDHC cards. The G9X Mark II supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the R-D1 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 G9 X Mark II and Epson R-D1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the G9X Mark II offers wifi support, while the R-D1 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
Studio photographers will appreciate that the Epson R-D1 (unlike the G9X Mark II) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
The G9X Mark II is a recent model that features in the current product line-up of Canon. In contrast, the R-D1 has been discontinued (but it can be found pre-owned on eBay). There has not been a direct replacement model for the R-D1 from Epson. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Epson websites.
So what conclusions can be drawn? Which of the two cameras – the Canon G9 X Mark II or the Epson R-D1 – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.
Reasons to prefer the Canon PowerShot G9 X Mark II:
- More detail: Offers more megapixels (20 vs 6MP) with a 82% higher linear resolution.
- Broader imaging potential: Can record not only still images but also 1080/60p movies.

Arguments in favor of the Epson R-D1:
- Easier framing: Has an optical viewfinder for image composition and settings control.
- More flexible: Takes interchangeable lenses and can thus be used with different optics.
- Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
- Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
- More heavily discounted: Has been around for much longer (launched in March 2004).
If the count of individual advantages (bullet points above) is taken as a guide, the G9X Mark II is the clear winner of the match-up (18 : 5 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.
In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the G9X Mark II and the R-D1 in practical situations. 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 where reviews by experts come in. 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. 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.
