Sony A58 vs HX99
The Sony Alpha SLT-A58 and the Sony Cyber-shot DSC-HX99 are two digital cameras that were announced, respectively, in February 2013 and August 2018. The A58 is a DSLR, while the HX99 is a fixed lens compact. The cameras are based on an APS-C (A58) and a 1/2.3-inch (HX99) sensor. The A58 has a resolution of 19.8 megapixels, whereas the HX99 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 SLT-A58 and the Sony Cyber-shot DSC-HX99? 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 A58 and the Sony HX99 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 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 HX99 is considerably smaller (52 percent) than the Sony A58. In this context, it is worth noting that neither the A58 nor the HX99 are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the HX99 has a lens built in, whereas the A58 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 A58 gets 690 shots out of its NP-FM500H battery, while the HX99 can take 370 images on a single charge of its NP-BX1 power pack. The power pack in the HX99 can be charged via the USB port, 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 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 HX99 was launched at a lower price than the A58, 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 imaging sensor is a crucial determinant 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. 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 associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Sony A58 features an APS-C sensor and the Sony HX99 a 1/2.3-inch sensor. The sensor area in the HX99 is 92 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 5.6. The sensor in the A58 has a native 3:2 aspect ratio, while the one in the HX99 offers a 4:3 aspect.
Technology-wise, the HX99 uses a more advanced image processing engine (BIONZ X) than the A58 (BIONZ), with benefits for noise reduction, color accuracy, and processing speed.
With 19.8MP, the A58 offers a higher resolution than the HX99 (18MP), but the A58 nevertheless has larger individual pixels (pixel pitch of 4.31μm versus 1.25μm for the HX99) due to its larger sensor. However, the HX99 is a much more recent model (by 5 years and 6 months) than the A58, 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 HX99 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Sony A58 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A58 for good quality output (200 dots per inch) amounts to 27.3 x 18.2 inches or 69.3 x 46.1 cm, for very good quality (250 dpi) 21.8 x 14.5 inches or 55.4 x 36.9 cm, and for excellent quality (300 dpi) 18.2 x 12.1 inches or 46.2 x 30.8 cm. The corresponding values for the Sony HX99 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 Sony Alpha SLT-A58 has a native sensitivity range from ISO 100 to ISO 16000, which can be extended to ISO 100-25600. The corresponding ISO settings for the Sony Cyber-shot DSC-HX99 are ISO 80 to ISO 3200, with the possibility to increase the ISO range to 80-6400.
Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. 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 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"). The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

|Note: DXO values in italics represent estimates based on sensor size and age.|
Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the HX99 provides a better video resolution than the A58. It can shoot movie footage at 4K/30p, while the A58 is limited to 1080/60i.
Apart from body and sensor, cameras can and do differ across a variety of features. The two cameras under consideration are similar with respect to both having an electronic viewfinder. However, the one in the A58 offers a substantially higher resolution than the one in the HX99 (1440k vs 638k dots). The adjacent table lists some of the other core features of the Sony A58 and Sony HX99 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 HX99 has a touchscreen, while the A58 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The HX99 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 A58 does not have a selfie-screen.
Concerning the storage of imaging data, both the A58 and the HX99 write their files to SDXC or Memory Stick PRO Duo cards. The HX99 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the A58 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 SLT-A58 and Sony Cyber-shot DSC-HX99 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

If the number of relative strengths (bullet points above) is taken as a guide, the HX99 is the clear winner of the contest (18 : 13 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 wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro 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 A58 and the Sony HX99 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 technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the A58 or the HX99 perform in practice. 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 why hands-on reviews by experts are important. The following table reports the overall ratings of the cameras as published by some of the major camera 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 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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
