Sony A9 II vs WX800
The Sony Alpha A9 II and the Sony Cyber-shot DSC-WX800 are two digital cameras that were revealed to the public, respectively, in October 2019 and October 2018. The A9 II is a mirrorless interchangeable lens camera, while the WX800 is a fixed lens compact. The cameras are based on a full frame (A9 II) and a 1/2.3-inch (WX800) sensor. The A9 II has a resolution of 24 megapixels, whereas the WX800 provides 18 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 Alpha A9 II and the Sony Cyber-shot DSC-WX800? 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 II and the Sony WX800 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 width, height and depth measures are rounded to the nearest millimeter.
The WX800 can be obtained in two different colors (black, white), while the A9 II 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 Sony WX800 is considerably smaller (52 percent) than the Sony A9 II. It is worth mentioning in this context that the A9 II is splash and dust resistant, while the WX800 does not feature any corresponding weather-sealing.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the WX800 has a lens built in, whereas the A9 II 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 II and their specifications in the Sony FE Lens Catalog.
Concerning battery life, the A9 II gets 690 shots out of its NP-FZ100 battery, while the WX800 can take 370 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.

Any camera decision will obviously take relative prices into account. 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 WX800 was launched at a lower price than the A9 II, 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 tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units 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 associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Sony A9 II features a full frame sensor and the Sony WX800 a 1/2.3-inch sensor. The sensor area in the WX800 is 97 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 5.6. The sensor in the A9 II has a native 3:2 aspect ratio, while the one in the WX800 offers a 4:3 aspect.
With 24MP, the A9 II offers a higher resolution than the WX800 (18MP), but the A9 II nevertheless has larger individual pixels (pixel pitch of 5.94μm versus 1.25μm for the WX800) due to its larger sensor. Moreover, the A9 II is a somewhat more recent model (by 11 months) than the WX800, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the WX800 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Sony A9 II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A9 II for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the Sony WX800 are 24.5 x 18.4 inches or 62.2 x 46.6 cm for good quality, 19.6 x 14.7 inches or 49.7 x 37.3 cm for very good quality, and 16.3 x 12.2 inches or 41.5 x 31.1 cm for excellent quality prints.
The A9 II has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Sony Alpha A9 II 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-WX800 are ISO 80 to ISO 3200, with the possibility to increase the ISO range to 80-6400.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. 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, and both provide the same movie specifications (4K/30p).
Beyond body and sensor, cameras can and do differ across a range of features. For example, the A9 II has an electronic viewfinder (3686k dots), which can be very helpful when shooting in bright sunlight. In contrast, the WX800 relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Sony A9 II, the Sony WX800, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The WX800 has one, while the A9 II does not. While the built-in flash of the WX800 is not very powerful, it can at times be useful as a fill-in light.The WX800 has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the A9 II does not have a selfie-screen.
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 II 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 Sony A9 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 A9 II writes its imaging data to SDXC cards, while the WX800 uses SDXC or Memory Stick PRO Duo cards. The A9 II features dual card slots, which can be very useful in case a memory card fails. In contrast, the WX800 only has one slot. The A9 II supports UHS-II cards (on both slots), while the WX800 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 II and Sony Cyber-shot DSC-WX800 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the A9 II has a hotshoe, while the WX800 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.
Studio photographers will appreciate that the Sony A9 II (unlike the WX800) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the A9 II and the WX800 are recent models that are part of the current product line-up. The WX800 replaced the earlier Sony WX500, while the A9 II followed on from the Sony A9. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Sony website.
So what conclusions can be drawn? Which of the two cameras – the Sony A9 II or the Sony WX800 – 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.

- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- Ready to shoot: Has an integrated lens, whereas the A9 II necessitates an extra lens.
- More compact: Is smaller (102x58mm vs 129x96mm) 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 II).
- 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 on the market for longer (launched in October 2018).
If the number of relative strengths (bullet points above) is taken as a guide, the A9 II is the clear winner of the match-up (24 : 8 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.
How about other alternatives? Do the specifications of the Sony A9 II and the Sony WX800 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best Superzoom 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 II or the WX800. 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 expert reviews 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], 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.

Care should be taken when interpreting the review scores above, though. The assessments were made in relation to similar cameras of the same technological generation. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
