Going beyond this snapshot of core features and characteristics, what are the differences between the Panasonic Lumix DMC-GF3 and the Ricoh GR? 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 Panasonic GF3 and the Ricoh GR is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter.

The GF3 can be obtained in five different colors (black, brown, pink, red, white), while the GR 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 Ricoh GR is somewhat smaller (1 percent) than the Panasonic GF3. In this context, it is worth noting that neither the GF3 nor the GR are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the GR has a lens built in, whereas the GF3 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 GF3 and their specifications in the Micro Four Thirds Lens Catalog.

Concerning battery life, the GF3 gets 300 shots out of its Panasonic DMW-BLE9 battery, while the GR can take 290 images on a single charge of its Ricoh DB-65 power pack. The power pack in the GR can be charged via the USB port, which can be very convenient when travelling.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. 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.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants 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 more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Panasonic GF3 features a Four Thirds sensor and the Ricoh GR an APS-C sensor. The sensor area in the GR 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 GF3 has a native 4:3 aspect ratio, while the one in the GR offers a 3:2 aspect.

With 16.1MP, the GR offers a higher resolution than the GF3 (12MP), but the GR nevertheless has larger individual pixels (pixel pitch of 4.79μm versus 4.33μm for the GF3) due to its larger sensor. Moreover, the GR is a somewhat more recent model (by 1 year and 10 months) than the GF3, and its sensor might 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 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Ricoh GR implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GR 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 GF3 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-GF3 has a native sensitivity range from ISO 160 to ISO 6400. The corresponding ISO settings for the Ricoh GR are ISO 100 to ISO 25600 (no boost).

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"). Of the two cameras under consideration, the GR offers substantially better image quality than the GF3 (overall score 28 points higher). The advantage is based on 3 bits higher color depth, 3.4 EV in additional dynamic range, and 1.1 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar 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 GF3 provides a higher frame rate than the GR. It can shoot video footage at 1080/60i, while the Ricoh is limited to 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The GF3 and the GR are similar in the sense that neither of the two has a viewfinder. The images are, thus, framed using live view on the rear LCD. That said, the GR can be equipped with an optional viewfinder – the GV-1. The table below summarizes some of the other core capabilities of the Panasonic GF3 and Ricoh GR in connection with corresponding information for a sample of similar cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The GF3 has a touchscreen, while the GR has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The Ricoh GR 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.

Concerning the storage of imaging data, both the GF3 and the GR write their files to SDXC cards. The GR supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the GF3 cannot take advantage of Ultra High Speed SD cards.

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 Panasonic Lumix DMC-GF3 and Ricoh GR and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the GR has a hotshoe, which makes it possible to easily attach optional accessories, such as an external flash gun. The GF3 does not feature such an accessory-socket.

Both the GF3 and the GR have been discontinued, but can regularly be found used on ebay. The GF3 was replaced by the Panasonic GF5, while the GR was followed by the Ricoh GR II. Further information on the features and operation of the GF3 and GR can be found, respectively, in the Panasonic GF3 Manual (free pdf) or the online Ricoh GR Manual.

Review summary

So how do things add up? Is the Panasonic GF3 better than the Ricoh GR or vice versa? The listing below highlights the relative strengths of the two models.

Advantages of the Panasonic Lumix DMC-GF3:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Better video: Provides higher movie framerates (1080/60i versus 1080/30p).
• Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
• More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
• More heavily discounted: Has been on the market for longer (launched in June 2011).

Reasons to prefer the Ricoh GR:

• 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 (28 points) in the DXO overall evaluation.
• Richer colors: Generates noticeably more natural colors (3 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 (1.1 stops ISO advantage).
• More framing options: Can be equipped with a hotshoe-mounted accessory-viewfinder.
• More detailed LCD: Has a higher resolution rear screen (1230k vs 460k dots).
• Faster burst: Shoots at higher frequency (4 vs 3.2 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 GF3 necessitates an extra lens.
• Less heavy: Has a lower weight even though it has a lens built in (unlike the GF3).
• Easier travel charging: Can be conveniently charged via its USB port.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More modern: Was introduced somewhat (1 year and 10 months) more recently.

If the count of individual advantages (bullet points above) is taken as a guide, the GR is the clear winner of the contest (16 : 5 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 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 Panasonic GF3 and the Ricoh GR 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it says little about, for example, the shooting experience and imaging performance of the GF3 and the GR 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 expert reviews are important. 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 review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. 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.
