Body comparison

An illustration of the physical size and weight of the Panasonic G3 and the Canon 5D Mark III 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 G3 can be obtained in four different colors (black, brown, red, white), while the 5D Mark III is only available in black.

Compare G3 versus 5D Mark III top
Comparison G3 or 5D Mark III rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon 5D Mark III is considerably larger (83 percent) than the Panasonic G3. Moreover, the 5D Mark III is substantially heavier (183 percent) than the G3. It is noteworthy in this context that the 5D Mark III is splash and dust-proof, while the G3 does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete since they do not consider the interchangeable lenses that both of these cameras require. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can compare the optics available for the two cameras in the Micro Four Thirds Lens Catalog (G3) and the Canon EF Lens Catalog (5D Mark III). Mirrorless cameras, such as the Panasonic G3, have moreover the advantage that they have a relatively short flange to focal plane distance and can thus use many lenses from other systems via adapters.

Concerning battery life, the G3 gets 270 shots out of its Panasonic DMW-BLD10 battery, while the 5D Mark III can take 950 images on a single charge of its Canon LP-E6 power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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 obviously take relative prices into account. 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. The G3 was launched at a markedly lower price (by 83 percent) than the 5D Mark 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.

Sensor comparison

The size of the imaging sensor is a crucial determinant of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have richer color-depth than smaller pixels 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 associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Panasonic G3 features a Four Thirds sensor and the Canon 5D Mark III a full frame sensor. The sensor area in the 5D Mark III is 284 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.0. The sensor in the G3 has a native 4:3 aspect ratio, while the one in the 5D Mark III offers a 3:2 aspect.

Panasonic G3 and Canon 5D Mark III sensor measures

With 22.1MP, the 5D Mark III offers a higher resolution than the G3 (15.8MP), but the 5D Mark III nevertheless has larger individual pixels (pixel pitch of 6.25μm versus 3.77μm for the G3) due to its larger sensor. Moreover, the 5D Mark III is a somewhat more recent model (by 9 months) than the G3, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.

The resolution advantage of the Canon 5D Mark III implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 5D Mark III for good quality output (200 dots per inch) amounts to 28.8 x 19.2 inches or 73.2 x 48.8 cm, for very good quality (250 dpi) 23 x 15.4 inches or 58.5 x 39 cm, and for excellent quality (300 dpi) 19.2 x 12.8 inches or 48.8 x 32.5 cm. The corresponding values for the Panasonic G3 are 23 x 17.2 inches or 58.3 x 43.8 cm for good quality, 18.4 x 13.8 inches or 46.7 x 35 cm for very good quality, and 15.3 x 11.5 inches or 38.9 x 29.2 cm for excellent quality prints.

The Panasonic Lumix DMC-G3 has a native sensitivity range from ISO 160 to ISO 6400. The corresponding ISO settings for the Canon EOS 5D Mark III are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 50-102400.

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.

G3 versus 5D Mark III MP

For many cameras, data on sensor performance has been reported by DXO Mark. 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 5D Mark III offers substantially better image quality than the G3 (overall score 25 points higher). The advantage is based on 3 bits higher color depth, 1.1 EV in additional dynamic range, and 1.8 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 can also record movies. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the G3 provides a higher frame rate than the 5D Mark III. It can shoot video footage at 1080/60i, while the Canon 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 G3 has an electronic viewfinder (1440k dots), while the 5D Mark III has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The viewfinders of both cameras offer the same field of view (100%), but the viewfinder of the 5D Mark III has a higher magnification than the one of the G3 (0.71x vs 0.70x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Panasonic G3 and Canon 5D Mark III in connection with corresponding information for a sample of similar cameras.

One difference between the cameras concerns the presence of an on-board flash. The G3 has one, while the 5D Mark III does not. While the built-in flash of the G3 is not very powerful, it can at times be useful as a fill-in light.

The G3 has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the 5D Mark III does not have a selfie-screen.

The G3 writes its imaging data to SDXC cards, while the 5D Mark III uses Compact Flash or SDXC cards. The 5D Mark III features dual card slots, which can be very useful in case a memory card fails. In contrast, the G3 only has one slot.

It is notable that the 5D Mark III has a headphone jack, which makes it possible to attach external headphones and monitor the quality of sound during the recording process. The G3 lacks such a headphone port.

Studio photographers will appreciate that the Canon 5D Mark III (unlike the G3) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the G3 and the 5D Mark III have been discontinued, but can regularly be found used on ebay. The G3 was replaced by the Panasonic G5, while the 5D Mark III was followed by the Canon 5D Mark IV. Further information on the features and operation of the G3 and 5D Mark III can be found, respectively, in the Panasonic G3 Manual (free pdf) or the online Canon 5D Mark III Manual.

  • More detailed LCD: Has a higher resolution rear screen (1040k vs 460k dots).
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
  • Faster burst: Shoots at higher frequency (6 vs 4 flaps/sec) to capture the decisive moment.
  • Longer lasting: Gets more shots (950 versus 270) out of a single battery charge.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
  • More modern: Was introduced somewhat (9 months) more recently.

If the count of relative strengths (bullet points above) is taken as a measure, the 5D Mark III is the clear winner of the contest (19 : 11 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.

G3 11:19 5D Mark III

How about other alternatives? Do the specifications of the Panasonic G3 and the Canon 5D Mark III place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best DSLR 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 G3 and the 5D Mark III in practical situations. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.

Expert reviews

This is why hands-on reviews by experts 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.

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. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
