Going beyond this snapshot of core features and characteristics, what are the differences between the Panasonic Lumix DMC-GM5 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 GM5 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 width, height and depth measures are rounded to the nearest millimeter.

The GM5 can be obtained in two different colors (black, silver), while the GR is only available in black.

Compare GM5 versus GR top
Comparison GM5 or GR rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Ricoh GR is notably larger (20 percent) than the Panasonic GM5. In this context, it is worth noting that neither the GM5 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 GM5 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 GM5 and their specifications in the Micro Four Thirds Lens Catalog.

Concerning battery life, the GM5 gets 220 shots out of its DMW-BLH7 battery, while the GR can take 290 images on a single charge of its DB65 power pack. The power pack in the GR 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.

Notes: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

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. 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.

Sensor comparison

The size of the imaging sensor is a crucial determinant 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Panasonic GM5 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 GM5 has a native 4:3 aspect ratio, while the one in the GR offers a 3:2 aspect.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.

Panasonic GM5 and Ricoh GR sensor measures

With 16.1MP, the GR offers a higher resolution than the GM5 (15.8MP), but the GR nevertheless has larger individual pixels (pixel pitch of 4.79μm versus 3.77μm for the GM5) due to its larger sensor. However, the GM5 is a somewhat more recent model (by 1 year and 4 months) than the GR, and its sensor might have benefitted from technological advances during this time that 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 Panasonic Lumix DMC-GM5 has a native sensitivity range from ISO 200 to ISO 25600, which can be extended to ISO 100-25600. The corresponding ISO settings for the Ricoh GR are ISO 100 to ISO 25600 (no boost).

GM5 versus GR MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). Of the two cameras under consideration, the GR offers substantially better image quality than the GM5 (overall score 12 points higher). The advantage is based on 1.5 bits higher color depth, 1.8 EV in additional dynamic range, and 0.4 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 GM5 provides a higher frame rate than the GR. It can shoot video footage at 1080/60p, 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. For example, the GM5 has an electronic viewfinder (1166k dots), which can be very helpful when shooting in bright sunlight. In contrast, the GR relies on live view and the rear LCD for framing. That said, the GR can be equipped with an optional viewfinder – the GV-1. The following table reports on some other key feature differences and similarities of the Panasonic GM5, the Ricoh GR, and comparable cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The GM5 has a touchscreen, while the GR has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

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 GM5 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 GM5 and the Ricoh GR 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.

Concerning the storage of imaging data, both the GM5 and the GR 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 Panasonic Lumix DMC-GM5 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 GM5 offers wifi support, while the GR does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Both the GM5 and the GR have been discontinued, but can regularly be found used on eBay. The GR was replaced by the Ricoh GR II, while the GM5 does not have a direct successor. 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

So how do things add up? Which of the two cameras – the Panasonic GM5 or the Ricoh GR – 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.

ilogo

Arguments in favor of the Panasonic Lumix DMC-GM5:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
  • Easier framing: Has an electronic viewfinder for image composition and settings control.
  • Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
  • Faster burst: Shoots at higher frequency (5.8 vs 4 flaps/sec) to capture the decisive moment.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
  • More compact: Is smaller (99x60mm vs 117x61mm) and thus needs less room in the bag.
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • More modern: Is somewhat more recent (announced 1 year and 4 months after the GR).

ilogo

Reasons to prefer the Ricoh GR:

  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Better image quality: Scores substantially higher (12 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (1.5 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (1.8 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (0.4 stops ISO advantage).
  • More detailed LCD: Has a higher resolution rear screen (1230k vs 921k dots).
  • Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/500s) to freeze action.
  • Ready to shoot: Has an integrated lens, whereas the GM5 necessitates an extra lens.
  • Longer lasting: Gets more shots (290 versus 220) out of a single battery charge.
  • Easier travel charging: Can be conveniently charged via its USB port.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • More heavily discounted: Has been on the market for longer (launched in April 2013).

If the count of relative strengths (bullet points above) is taken as a measure, the GR emerges as the winner of the match-up (12 : 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 wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

GM5 10:12 GR

How about other alternatives? Do the specifications of the Panasonic GM5 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 comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the GM5 or the GR perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

This is why expert reviews are important. The following table reports the overall ratings of the cameras as published by some of the major 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.

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. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
