Sony A900 vs WX800
The Sony Alpha A900 and the Sony Cyber-shot DSC-WX800 are two digital cameras that were revealed to the public, respectively, in September 2008 and October 2018. The A900 is a DSLR, while the WX800 is a fixed lens compact. The cameras are based on a full frame (A900) and a 1/2.3-inch (WX800) sensor. The A900 has a resolution of 24.4 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 A900 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 side-by-side display below illustrates the physical size and weight of the Sony A900 and the Sony WX800. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. 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 A900 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 (68 percent) than the Sony A900. It is worth mentioning in this context that the A900 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 A900 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup.
Concerning battery life, the A900 gets 880 shots out of its NP-FM500H battery, while the WX800 can take 370 images on a single charge of its NP-BX1 power pack. The power pack in the WX800 can be charged via the USB port, which can be very convenient 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 listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The WX800 was launched at a lower price than the A900, 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.
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. 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Sony A900 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 A900 has a native 3:2 aspect ratio, while the one in the WX800 offers a 4:3 aspect.
With 24.4MP, the A900 offers a higher resolution than the WX800 (18MP), but the A900 nevertheless has larger individual pixels (pixel pitch of 5.94μm versus 1.25μm for the WX800) due to its larger sensor. However, the WX800 is a much more recent model (by 10 years and 1 month) than the A900, and its sensor will 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 A900 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A900 for good quality output (200 dots per inch) amounts to 30.2 x 20.2 inch or 76.8 x 51.2 cm, for very good quality (250 dpi) 24.2 x 16.1 inch or 61.4 x 41 cm, and for excellent quality (300 dpi) 20.2 x 13.4 inch or 51.2 x 34.1 cm. The corresponding values for the Sony WX800 are 24.5 x 18.4 inch or 62.2 x 46.6 cm for good quality, 19.6 x 14.7 inch or 49.7 x 37.3 cm for very good quality, and 16.3 x 12.2 inch or 41.5 x 31.1 cm for excellent quality prints.
The Sony Alpha A900 has a native sensitivity range from ISO 200 to ISO 3200, which can be extended to ISO 100-6400. 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.
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").

Many modern cameras are not only capable of taking still images, but can also record movies. The WX800 indeed provides for movie recording, while the A900 does not. The highest resolution format that the WX800 can use is 4K/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the A900 has an optical viewfinder, which can be very useful 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 A900, the Sony WX800, and comparable cameras.

One feature that is present on the A900, but is missing on the WX800 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 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 A900 does not have a selfie-screen.
The A900 writes its imaging data to Compact Flash or Memory Stick PRO Duo cards, while the WX800 uses SDXC or Memory Stick PRO Duo cards. The A900 features dual card slots, which can be very useful in case a memory card fails. In contrast, the WX800 only has one slot.
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 A900 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 A900 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 A900 (unlike the WX800) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
The WX800 is a recent model that features in the current product line-up of Sony. In contrast, the A900 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the A900 was succeeded by the Sony A99. 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 is the bottom line? Is there a clear favorite between the Sony A900 and the Sony WX800? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.
Arguments in favor of the Sony Alpha A900:

If the number of relative strengths (bullet points above) is taken as a guide, the A900 emerges as the winner of the contest (16 : 14 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 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 A900 and the Sony WX800 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Superzoom Camera listings whether the two cameras rank among the cream of the crop.
In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the A900 or the WX800. 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.
The above review scores should be interpreted 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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
