Body comparison

The physical size and weight of the Sony A7 IV 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.

Size Sony A7 IV vs Sony HX99
Compare A7 IV versus HX99 top
Comparison A7 IV or HX99 rear

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 (53 percent) than the Sony A7 IV. It is worth mentioning in this context that the A7 IV is splash and dust resistant, while the HX99 does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the HX99 has a lens built in, whereas the A7 IV 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 A7 IV and their specifications in the Sony FE Lens Catalog.

Concerning battery life, the A7 IV gets 580 shots out of its Sony NP-FZ100 battery, while the HX99 can take 370 images on a single charge of its Sony 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 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 A7 IV, 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.

Sensor comparison

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 A7 IV features a full frame sensor and the Sony HX99 a 1/2.3-inch sensor. The sensor area in the HX99 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 A7 IV has a native 3:2 aspect ratio, while the one in the HX99 offers a 4:3 aspect.

In terms of chip-set technology, the A7 IV uses a more advanced image processing engine (BIONZ XR) than the HX99 (BIONZ X), with benefits for noise reduction, color accuracy, and processing speed.

Sony A7 IV and Sony HX99 sensor measures

With 32.7MP, the A7 IV offers a higher resolution than the HX99 (18MP), but the A7 IV nevertheless has larger individual pixels (pixel pitch of 5.12μm versus 1.25μm for the HX99) due to its larger sensor. Moreover, the A7 IV is a much more recent model (by 3 years and 1 month) than the HX99, 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 neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.

The resolution advantage of the Sony A7 IV implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A7 IV for good quality output (200 dots per inch) amounts to 35 x 23.4 inches or 89 x 59.3 cm, for very good quality (250 dpi) 28 x 18.7 inches or 71.2 x 47.5 cm, and for excellent quality (300 dpi) 23.4 x 15.6 inches or 59.3 x 39.6 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 A7 IV has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Sony Alpha A7 IV 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-HX99 are ISO 80 to ISO 3200, with the possibility to increase the ISO range to 80-6400.

In terms of underlying technology, the A7 IV is build around a BSI-CMOS sensor, while the HX99 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.

A7 IV versus HX99 MP

One difference between the cameras concerns the presence of an on-board flash. The HX99 has one, while the A7 IV does not. While the built-in flash of the HX99 is not very powerful, it can at times be useful as a fill-in light.

Both cameras have an articulated rear screen that can be turned to be front-facing. This feature will be particularly appreciated by vloggers and photographers who are interested in taking selfies.

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 A7 IV 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 A7 IV writes its imaging data to CFexpress (type A) or SDXC cards, while the HX99 uses SDXC or Memory Stick PRO Duo cards. The A7 IV features dual card slots, which can be very useful in case a memory card fails. In contrast, the HX99 only has one slot. The A7 IV supports UHS-II cards (on both slots), while the HX99 can use UHS-I cards.

  • More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/2000s) to freeze action.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
  • Longer lasting: Can take more shots (580 versus 370) on a single battery charge.
  • Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
  • Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
  • Faster data transfer: Supports a more advanced USB protocol (3.2 vs 2.0).

  • More modern: Reflects 3 years and 1 month of technical progress since the HX99 launch.


Arguments in favor of the Sony Cyber-shot DSC-HX99:

  • Ready to shoot: Has an integrated lens, whereas the A7 IV necessitates an extra lens.
  • More compact: Is smaller (102x58mm vs 131x96mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight even though it has a lens built in (unlike the A7 IV).
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • 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 August 2018).

If the count of relative strengths (bullet points above) is taken as a measure, the A7 IV is the clear winner of the match-up (24 : 7 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.

A7 IV 24:07 HX99

How about other alternatives? Do the specifications of the Sony A7 IV and the Sony HX99 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 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 A7 IV or the HX99. 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.

Expert reviews

This is where reviews by experts come in. The adjacent summary-table relays the overall verdicts of several of the most popular 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 above review scores should be interpreted 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.
