Going beyond this snapshot of core features and characteristics, what are the differences between the Sony Alpha SLT-A77 II 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.

Body comparison

An illustration of the physical size and weight of the Sony A77 II and the Sony HX99 is provided in the side-by-side display below. 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.

Compare A77 II versus HX99 top
Comparison A77 II 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 (60 percent) than the Sony A77 II. It is worth mentioning in this context that the A77 II 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 A77 II 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 A77 II gets 480 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.

Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.

The price is, of course, an important factor in any camera decision. 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 A77 II, 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. 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 A77 II 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 A77 II has a native 3:2 aspect ratio, while the one in the HX99 offers a 4:3 aspect.

Sony A77 II and Sony HX99 sensor measures

With 24MP, the A77 II offers a higher resolution than the HX99 (18MP), but the A77 II nevertheless has larger individual pixels (pixel pitch of 3.91μm versus 1.25μm for the HX99) due to its larger sensor. However, the HX99 is a much more recent model (by 4 years and 4 months) than the A77 II, 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 A77 II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A77 II for good quality output (200 dots per inch) amounts to 30 x 20 inch or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inch or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inch or 50.8 x 33.9 cm. The corresponding values for the Sony HX99 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 SLT-A77 II has a native sensitivity range from ISO 100 to ISO 25600, which can be extended to ISO 50-51200. 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.

One feature that is present on the A77 II, but is missing on the HX99 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.

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.

Concerning the storage of imaging data, both the A77 II and the HX99 write their files to SDXC or Memory Stick PRO Duo cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.

 

Connectivity comparison

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.

It is notable that the A77 II has a hotshoe, while the HX99 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 A77 II (unlike the HX99) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the A77 II and the HX99 are recent models that are part of the current product line-up. The A77 II replaced the earlier Sony A77, while the HX99 does not have a direct predecessor. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Sony website.


Review summary

So what conclusions can be drawn? Is there a clear favorite between the Sony A77 II and the Sony HX99? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.


Reasons to prefer the Sony Alpha SLT-A77 II:

  • More detail: Offers more megapixels (24 vs 18MP) with a 18% higher linear resolution.
  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
  • Richer colors: The pixel size advantage translates into images with better, more accurate colors.
  • More dynamic range: Larger pixels capture a wider spectrum of light and dark details.
  • Better low-light sensitivity: Larger pixels means good image quality even under poor lighting.
  • Better sound: Can connect to an external microphone for higher quality sound recording.
  • More detailed viewfinder: Has higher resolution electronic viewfinder (2359k vs 638k dots).
  • Easier setting verification: Features an LCD display on top to control shooting parameters.
  • More detailed LCD: Has a higher resolution rear screen (1229k vs 922k dots).
  • More flexible LCD: Has a full-flex 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.
  • Faster burst: Shoots at higher frequency (12 vs 10 flaps/sec) to capture the decisive moment.
  • More flexible: Can take a variety of interchangeable lenses, including specialty optics.
  • Longer lasting: Can take more shots (480 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.
  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • More heavily discounted: Has been available for much longer (launched in May 2014).


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

  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • Ready to shoot: Comes with an integrated lens, while the A77 II requires a separate lens.
  • More compact: Is smaller (102x58mm vs 143x104mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight even though it has a lens built in (unlike the A77 II).
  • Easier travel charging: Can be conveniently charged via its USB port.
  • Easier wireless transfer: Supports Bluetooth for image sharing without cables.
  • More affordable: Was introduced at a lower price, despite coming with a built-in lens.
  • More modern: Reflects 4 years and 4 months of technical progress since the A77 II launch.

If the number of relative strengths (bullet points above) is taken as a guide, the A77 II is the clear winner of the match-up (19 : 9 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 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.

A77 II 19:09 HX99

How about other alternatives? Do the specifications of the Sony A77 II 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 A77 II or the HX99 perform in practice. 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.

Expert reviews

This is why hands-on reviews by experts are important. The adjacent summary-table relays the overall verdicts of several of the most popular 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 review scores listed above should be treated with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, 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.
