Any camera decision will naturally be influenced heavily by the price. 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 HX99 was launched at a markedly lower price (by 55 percent) than the GR IIIx, which puts it into a different market segment. 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.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants 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. 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 Ricoh GR IIIx 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 GR IIIx has a native 3:2 aspect ratio, while the one in the HX99 offers a 4:3 aspect.

With 24MP, the GR IIIx offers a higher resolution than the HX99 (18MP), but the GR IIIx nevertheless has larger individual pixels (pixel pitch of 3.91μm versus 1.25μm for the HX99) due to its larger sensor. Moreover, the GR IIIx is a much more recent model (by 3 years) 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 Ricoh GR IIIx implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GR IIIx 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 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 GR IIIx has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Ricoh GR IIIx has a native sensitivity range from ISO 100 to ISO 102400. 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.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. 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 GR IIIx. It can shoot movie footage at 4K/30p, while the Ricoh is limited to 1080/60p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the HX99 has an electronic viewfinder (638k dots), which can be very helpful when shooting in bright sunlight. In contrast, the GR IIIx relies on live view and the rear LCD for framing. That said, the GR IIIx can be equipped with an optional viewfinder – the GV-3. The adjacent table lists some of the other core features of the Ricoh GR IIIx and Sony HX99 along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The HX99 has one, while the GR IIIx 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.

The Ricoh GR IIIx 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 HX99 is equipped with a zoom lens, while the GR IIIx comes with a built-in prime. The HX99 has a 24-720mm f/3.5-6.4 optic and the GR IIIx offers a 40mm f/2.8 (focal lengths in full frame equivalent terms). Hence, the Sony provides a wider angle of view at the short end, as well as more tele-photo reach at the long end than the Ricoh. The GR IIIx offers the faster maximum aperture.

The GR IIIx writes its imaging data to SDXC cards, while the HX99 uses 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. The table below provides an overview of the connectivity of the Ricoh GR IIIx and Sony Cyber-shot DSC-HX99 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the GR IIIx has a hotshoe, while the HX99 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

The GR IIIx is a recent model that features in the current product line-up of Ricoh. In contrast, the HX99 has been discontinued (but can be found pre-owned on ebay). There has not been a direct replacement model for the HX99 from Sony. Further information on the features and operation of the GR IIIx and HX99 can be found, respectively, in the Ricoh GR IIIx Manual (free pdf) or the online Sony HX99 Manual.

Review summary

So how do things add up? Is there a clear favorite between the Ricoh GR IIIx and the Sony HX99? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

Advantages of the Ricoh GR IIIx:

• More detail: Offers more megapixels (24 vs 18MP) with a 18% higher linear resolution.
• Better image quality: Features a larger and more technologically advanced imaging sensor.
• Richer colors: The sensor size advantage translates into images with better, more accurate colors.
• More dynamic range: Larger sensor captures a wider spectrum of light and dark details.
• Better low-light sensitivity: Larger sensor produces good images even in poorly lit environments.
• Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
• More detailed LCD: Has a higher resolution rear screen (1037k vs 922k dots).
• Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• Better light gathering: Has a lens with a wider maximum aperture (f/2.8 vs f/3.5).
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• Faster data transfer: Supports a more advanced USB protocol (3.0 vs 2.0).
• More modern: Reflects 3 years of technical progress since the HX99 launch.

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

• Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
• Easier framing: Has an electronic viewfinder for image composition and settings control.
• More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Faster burst: Shoots at higher frequency (10 vs 4 flaps/sec) to capture the decisive moment.
• Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
• More compact: Is smaller (102x58mm vs 109x62mm) and will fit more readily into a bag.
• Longer lasting: Gets more shots (370 versus 200) out of a single battery charge.
• 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 into a lower priced category (55 percent cheaper at launch).
• More heavily discounted: Has been around for much longer (launched in August 2018).

If the count of individual advantages (bullet points above) is taken as a guide, the GR IIIx comes out slightly ahead of the HX99 (13 : 12 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 Ricoh GR IIIx and the Sony HX99 place the cameras among the top in their class? Find out in the latest Best Prime Lens Compact 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 says little about, for example, the shooting experience and imaging performance of the GR IIIx and the HX99 in practical situations. 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 (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 ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
