Going beyond this snapshot of core features and characteristics, what are the differences between the Ricoh GR III and the Panasonic Lumix DC-ZS80? 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 Ricoh GR III and the Panasonic ZS80 is provided 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 size dimensions are rounded to the nearest millimeter.

The ZS80 can be obtained in two different colors (black, silver), while the GR III 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 Panasonic ZS80 is notably larger (14 percent) than the Ricoh GR III. Moreover, the ZS80 is markedly heavier (27 percent) than the GR III. In this context, it is worth noting that neither the GR III nor the ZS80 are weather-sealed.

Concerning battery life, the GR III gets 200 shots out of its Ricoh DB-110 battery, while the ZS80 can take 380 images on a single charge of its Panasonic DMW-BLG10 power pack. The battery packs of both cameras can be charged via USB, which can be very convenient when travelling.

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 ZS80 was launched at a markedly lower price (by 50 percent) than the GR III, 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 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Ricoh GR III features an APS-C sensor and the Panasonic ZS80 a 1/2.3-inch sensor. The sensor area in the ZS80 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 III has a native 3:2 aspect ratio, while the one in the ZS80 offers a 4:3 aspect.

With 24MP, the GR III offers a higher resolution than the ZS80 (20.2MP), but the GR III nevertheless has larger individual pixels (pixel pitch of 3.91μm versus 1.18μm for the ZS80) due to its larger sensor. It is noteworthy in this context that the two cameras were released in close succession, so that their sensors are from the same technological generation. 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 III implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GR III 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 Panasonic ZS80 are 25.9 x 19.4 inches or 65.8 x 49.4 cm for good quality, 20.7 x 15.6 inches or 52.7 x 39.5 cm for very good quality, and 17.3 x 13 inches or 43.9 x 32.9 cm for excellent quality prints.

The GR III has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Ricoh GR III has a native sensitivity range from ISO 100 to ISO 102400. The corresponding ISO settings for the Panasonic Lumix DC-ZS80 are ISO 80 to ISO 3200, with the possibility to increase the ISO range to 80-6400.

In terms of underlying technology, the GR III is build around a CMOS sensor, while the ZS80 uses a BSI-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.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the ZS80 provides a better video resolution than the GR III. 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 range of features. For example, the ZS80 has an electronic viewfinder (2330k dots), which can be very helpful when shooting in bright sunlight. In contrast, the GR III relies on live view and the rear LCD for framing. That said, the GR III can be equipped with an optional viewfinder – the GV-1. The adjacent table lists some of the other core features of the Ricoh GR III and Panasonic ZS80 along with similar information for a selection of comparators.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One difference between the cameras concerns the presence of an on-board flash. The ZS80 has one, while the GR III does not. While the built-in flash of the ZS80 is not very powerful, it can at times be useful as a fill-in light.

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 ZS80 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 Ricoh GR III 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 ZS80 is equipped with a zoom lens, while the GR III comes with a built-in prime. The ZS80 has a 24-720mm f/3.3-6.4 optic and the GR III offers a 28mm f/2.8 (focal lengths in full frame equivalent terms). Hence, the Panasonic 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 III offers the faster maximum aperture.

Concerning the storage of imaging data, both the GR III and the ZS80 write their files to SDXC 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 III and Panasonic Lumix DC-ZS80 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the GR III has a hotshoe, while the ZS80 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

The GR III is a recent model that features in the current product line-up of Ricoh. In contrast, the ZS80 has been discontinued (but can be found pre-owned on ebay). There has not been a direct replacement model for the ZS80 from Panasonic. Further information on the features and operation of the GR III and ZS80 can be found, respectively, in the Ricoh GR III Manual (free pdf) or the online Panasonic ZS80 Manual.

Review summary

So what is the bottom line? Which of the two cameras – the Ricoh GR III or the Panasonic ZS80 – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.

Arguments in favor of the Ricoh GR III:

• More detail: Offers more megapixels (24 vs 20.2MP) with a 11% higher linear resolution.
• 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 live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
• 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/3.3).
• More compact: Is smaller (109x62mm vs 112x69mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 70g or 21 percent) and hence easier to carry around.
• 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).

Advantages of the Panasonic Lumix DC-ZS80:

• 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.
• Less disturbing: Has an electronic shutter option for completely silent shooting.
• Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
• Longer lasting: Gets more shots (380 versus 200) out of a single battery charge.
• Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
• More affordable: Was introduced into a lower priced category (50 percent cheaper at launch).

If the number of relative strengths (bullet points above) is taken as a guide, the GR III emerges as the winner of the contest (13 : 10 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.

How about other alternatives? Do the specifications of the Ricoh GR III and the Panasonic ZS80 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 technical specifications can provide a useful overview of the capabilities of different cameras, it says little about, for example, the shooting experience and imaging performance of the GR III and the ZS80 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 where reviews by experts come in. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
