Panasonic G1 vs Ricoh GR II
The Panasonic Lumix DMC-G1 and the Ricoh GR II are two digital cameras that were announced, respectively, in September 2008 and June 2015. The G1 is a mirrorless interchangeable lens camera, while the GR II is a fixed lens compact. The cameras are based on a Four Thirds (G1) and an APS-C (GR II) sensor. The Panasonic has a resolution of 12 megapixels, whereas the Ricoh provides 16.1 MP.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.
Going beyond this snapshot of core features and characteristics, what are the differences between the Panasonic Lumix DMC-G1 and the Ricoh GR II? 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.
An illustration of the physical size and weight of the Panasonic G1 and the Ricoh GR II 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.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Ricoh GR II is notably smaller (29 percent) than the Panasonic G1. In this context, it is worth noting that neither the G1 nor the GR II are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the GR II has a lens built in, whereas the G1 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 G1 and their specifications in the Micro Four Thirds Lens Catalog.
Concerning battery life, the G1 gets 410 shots out of its DMW-BLB13 battery, while the GR II can take 320 images on a single charge of its DB65 power pack. The power pack in the GR II can be charged via the USB port, 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. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

|Notes: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.|
The price is, of course, an important factor in any camera decision. 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. 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.
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. 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 associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Panasonic G1 features a Four Thirds sensor and the Ricoh GR II an APS-C sensor. The sensor area in the GR II is 64 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.5. The sensor in the G1 has a native 4:3 aspect ratio, while the one in the GR II offers a 3:2 aspect.
With 16.1MP, the GR II offers a higher resolution than the G1 (12MP), but the GR II nevertheless has larger individual pixels (pixel pitch of 4.79μm versus 4.33μm for the G1) due to its larger sensor. Moreover, the GR II is a much more recent model (by 6 years and 9 months) than the G1, 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 II has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Ricoh GR II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GR II for good quality output (200 dots per inch) amounts to 24.6 x 16.3 inches or 62.6 x 41.5 cm, for very good quality (250 dpi) 19.7 x 13.1 inches or 50.1 x 33.2 cm, and for excellent quality (300 dpi) 16.4 x 10.9 inches or 41.7 x 27.6 cm. The corresponding values for the Panasonic G1 are 20 x 15 inches or 50.8 x 38.1 cm for good quality, 16 x 12 inches or 40.6 x 30.5 cm for very good quality, and 13.3 x 10 inches or 33.9 x 25.4 cm for excellent quality prints.
The Panasonic Lumix DMC-G1 has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 100-3200. The corresponding ISO settings for the Ricoh GR II are ISO 100 to ISO 25600 (no boost).
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. Of the two cameras under consideration, the GR II offers substantially better image quality than the G1 (overall score 27 points higher). The advantage is based on 2.5 bits higher color depth, 3.4 EV in additional dynamic range, and 1.2 stops in additional low light sensitivity. 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. The GR II indeed provides for movie recording, while the G1 does not. The highest resolution format that the GR II can use is 1080/30p.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the G1 has an electronic viewfinder (1440k dots), which can be very helpful when shooting in bright sunlight. In contrast, the GR II relies on live view and the rear LCD for framing. That said, the GR II can be equipped with an optional viewfinder – the GV-1. The adjacent table lists some of the other core features of the Panasonic G1 and Ricoh GR II along with similar information for a selection of comparators.

The Ricoh GR II 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 G1 writes its imaging data to SDHC cards, while the GR II uses SDXC cards. The GR II supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the G1 cannot take advantage of Ultra High Speed SD cards.
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-G1 and Ricoh GR II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the GR II offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the G1 does not provide wifi capability.
The GR II is a recent model that features in the current product line-up of Ricoh. In contrast, the G1 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the G1 was succeeded by the Panasonic G2. 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.
So what conclusions can be drawn? Is there a clear favorite between the Panasonic G1 and the Ricoh GR II? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.
Arguments in favor of the Panasonic Lumix DMC-G1:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Easier framing: Has an electronic viewfinder for image composition and settings control.
- More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.

- Longer lasting: Can take more shots (410 versus 320) on a single battery charge.
- More heavily discounted: Has been available for much longer (launched in September 2008).
Advantages of the Ricoh GR II:
- More detail: Has more megapixels (16.1 vs 12MP), which boosts linear resolution by 18%.
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Better image quality: Scores substantially higher (27 points) in the DXO overall evaluation.
- Richer colors: Generates noticeably more natural colors (2.5 bits more color depth).
- More dynamic range: Captures a broader range of light and dark details (3.4 EV of extra DR).
- Better low-light sensitivity: Can shoot in dim conditions (1.2 stops ISO advantage).
- Broader imaging potential: Can capture not only stills but also 1080/30p video.
- More detailed LCD: Has a higher resolution rear screen (1230k vs 460k dots).
- Faster burst: Shoots at higher frequency (4 vs 3 flaps/sec) to capture the decisive moment.
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- Ready to shoot: Has an integrated lens, whereas the G1 necessitates an extra lens.
- More compact: Is smaller (117x63mm vs 124x84mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight even though it has a lens built in (unlike the G1).
- Easier travel charging: Can be conveniently charged via its USB port.
- Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
- Easier device pairing: Supports NFC for fast wireless image transfer over short distances.

If the count of individual advantages (bullet points above) is taken as a guide, the GR II is the clear winner of the contest (18 : 7 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera. A professional sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape 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 Panasonic G1 and the Ricoh GR II place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best Prime Lens Compact 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 G1 and the GR II 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.
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.

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. 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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
