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

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The TZ100 was launched at a somewhat lower price (by 22 percent) than the GR III, which makes it more attractive for photographers on a tight budget. 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: Panasonic TZ100 vs Ricoh GR III

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units 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 more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Panasonic TZ100 features an one-inch sensor and the Ricoh GR III an APS-C sensor. The sensor area in the GR III is 216 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

In terms of underlying technology, both cameras are build around CMOS sensors.

Panasonic TZ100 and Ricoh GR III sensor measures

With 24MP, the GR III offers a higher resolution than the TZ100 (20MP), but the GR III nevertheless has larger individual pixels (pixel pitch of 3.91μm versus 2.41μm for the TZ100) due to its larger sensor. Moreover, the GR III is a much more recent model (by 3 years and 1 month) than the TZ100, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the GR III has no anti-alias filter installed, so that it can capture all the detail its 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 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 Panasonic TZ100 are 27.4 x 18.2 inch or 69.5 x 46.3 cm for good quality, 21.9 x 14.6 inch or 55.6 x 37.1 cm for very good quality, and 18.2 x 12.2 inch or 46.3 x 30.9 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 Panasonic Lumix DMC-TZ100 has a native sensitivity range from ISO 125 to ISO 12800, which can be extended to ISO 80-25600. The corresponding ISO settings for the Ricoh GR III are ISO 100 to ISO 102400 (no boost).

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the TZ100 provides a higher video resolution than the GR III. It can shoot video footage at 4K/30p, while the Ricoh is limited to 1080/60p.

 

Feature comparison: Panasonic TZ100 vs Ricoh GR III

Beyond body and sensor, cameras can and do differ across a range of features. For example, the TZ100 has an electronic viewfinder (1166k 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.

One difference between the cameras concerns the presence of an on-board flash. The TZ100 has one, while the GR III does not. While the built-in flash of the TZ100 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 TZ100 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 Panasonic TZ100 and the Ricoh GR III both have 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 TZ100 is equipped with a zoom lens, while the GR III comes with a built-in prime. The TZ100 has a 25-250mm f/2.8-5.9 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. Both cameras offer the same maximum aperture.

Concerning the storage of imaging data, both the TZ100 and the GR III 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: Panasonic TZ100 vs Ricoh GR III

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 Panasonic Lumix DMC-TZ100 and Ricoh GR III 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, which makes it possible to easily attach optional accessories, such as an external flash gun. The TZ100 does not feature such an accessory-socket.

The GR III is a recent model that features in the current product line-up of Ricoh. In contrast, the TZ100 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the TZ100 was succeeded by the Panasonic TZ200. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Panasonic and Ricoh websites.


Review summary: Panasonic TZ100 vs Ricoh GR III

So how do things add up? Is there a clear favorite between the Panasonic TZ100 and the Ricoh GR III? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

  • 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.
  • Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
  • Less heavy: Has a lower weight (by 55g or 18 percent) and is thus easier to take along.
  • 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).
  • Easier wireless transfer: Supports Bluetooth for image sharing without cables.
  • More modern: Reflects 3 years and 1 month of technical progress since the TZ100 launch.

If the count of relative strengths (bullet points above) is taken as a measure, the GR III emerges as the winner of the match-up (13 : 10 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.

Notes: (+ +) 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 comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
