Sony A9 vs RX1R
The Sony Alpha A9 and the Sony Cyber-shot DSC-RX1R are two digital cameras that were officially introduced, respectively, in April 2017 and June 2013. The A9 is a mirrorless interchangeable lens camera, while the RX1R is a fixed lens compact. Both cameras are equipped with a full frame sensor. Both cameras offer a resolution of 24 megapixels.
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 Alpha A9 and the Sony Cyber-shot DSC-RX1R? 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 physical size and weight of the Sony A9 and the Sony RX1R are illustrated 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.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony RX1R is considerably smaller (40 percent) than the Sony A9. It is worth mentioning in this context that the A9 is splash and dust resistant, while the RX1R does not feature any corresponding weather-sealing.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the RX1R has a lens built in, whereas the A9 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 A9 and their specifications in the Sony FE Lens Catalog.
Concerning battery life, the A9 gets 650 shots out of its NP-FZ100 battery, while the RX1R can take 270 images on a single charge of its NP-BX1 power pack. The battery packs of both cameras can be charged via USB, which can be very convenient when travelling.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

The price is, of course, an important factor in any camera decision. 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 RX1R was launched at a lower price than the A9, despite having a lens built in. 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.
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 tend to be more expensive and lead to bigger and heavier cameras and lenses.
Both cameras under consideration feature a full frame sensor, but their sensors differ slightly in size. The sensor area in the RX1R is 1 percent bigger. They nevertheless have the same format factor of 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
Even though the RX1R has a slightly larger sensor, both cameras offer the same resolution of 24 megapixels. This implies that the RX1R has a lower pixel density and marginally larger individual pixels (with a pixel pitch of 5.97μm versus 5.94μm for the A9), which gives it a potential advantage in terms of light gathering capacity. It should, however, be noted that the A9 is much more recent (by 3 years and 9 months) than the RX1R, and its sensor will have benefitted from technological advances during this time that at least partly compensate for the smaller pixel size. Coming back to sensor resolution, it should be mentioned that the RX1R has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The A9 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Sony Alpha A9 has a native sensitivity range from ISO 100 to ISO 51200, which can be extended to ISO 50-204800. The corresponding ISO settings for the Sony Cyber-shot DSC-RX1R are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 50-102400.
In terms of underlying technology, the A9 is build around a Stacked BSI-CMOS sensor, while the RX1R uses a 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.
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 Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. 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 cannot only take still pictures, but also record videos. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the A9 provides a higher video resolution than the RX1R. It can shoot video footage at 4K/30p, while the RX1R is limited to 1080/60p.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the A9 has an electronic viewfinder (3686k dots), which can be very helpful when shooting in bright sunlight. In contrast, the RX1R relies on live view and the rear LCD for framing. That said, the RX1R can be equipped with an optional viewfinder – the FDA-EV1MK. The table below summarizes some of the other core capabilities of the Sony A9 and Sony RX1R in connection with corresponding information for a sample of similar cameras.

|Notes: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.|
One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The A9 has a touchscreen, while the RX1R has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.
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 A9 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).
Concerning the storage of imaging data, both the A9 and the RX1R write their files to SDXC or Memory Stick PRO Duo cards. The A9 features dual card slots, which can be very useful in case a memory card fails. In contrast, the RX1R only has one slot. The A9 supports UHS-II cards on its first slot and UHS-I on its second one, while the RX1R 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 Sony Alpha A9 and Sony Cyber-shot DSC-RX1R and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the A9 offers wifi support, while the RX1R does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
Studio photographers will appreciate that the Sony A9 (unlike the RX1R) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the A9 and the RX1R have been discontinued, but can regularly be found used on ebay. The RX1R was replaced by the Sony RX1R II, while the A9 was followed by the Sony A9 II. Further information on the features and operation of the A9 and RX1R can be found, respectively, in the Sony A9 Manual (free pdf) or the online Sony RX1R Manual.
So what is the bottom line? Is there a clear favorite between the Sony A9 and the Sony RX1R? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

Reasons to prefer the Sony Cyber-shot DSC-RX1R:
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Ready to shoot: Has an integrated lens, whereas the A9 necessitates an extra lens.
- More compact: Is smaller (113x65mm vs 127x96mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight even though it has a lens built in (unlike the A9).
- Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
- More affordable: Was introduced at a lower price, despite coming with a built-in lens.
- More heavily discounted: Has been around for much longer (launched in June 2013).
If the number of relative strengths (bullet points above) is taken as a guide, the A9 is the clear winner of the match-up (23 : 7 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape 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 Sony A9 and the Sony RX1R place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best Prime Lens Compact Camera listings 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 partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the A9 or the RX1R. 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.
This is why hands-on reviews by experts are important. 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. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, 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.
