Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS 5D and the Panasonic Lumix DMC-G5? 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 Canon 5D and the Panasonic G5 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.

The G5 can be obtained in two different colors (black, silver), while the 5D 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 Panasonic G5 is considerably smaller (42 percent) than the Canon 5D. Moreover, the G5 is substantially lighter (56 percent) than the 5D. It is worth mentioning in this context that the 5D is splash and dust resistant, while the G5 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 Canon EF Lens Catalog (5D) and the Micro Four Thirds Lens Catalog (G5). Mirrorless cameras, such as the G5, have moreover the advantage that they can use many lenses from other systems via adapters, as they have a relatively short flange to focal plane distance.

Concerning battery life, the 5D gets 400 shots out of its Canon BP-511A battery, while the G5 can take 320 images on a single charge of its Panasonic DMW-BLC12 power pack.

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.

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. The G5 was launched at a markedly lower price (by 82 percent) than the 5D, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

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 Canon 5D features a full frame sensor and the Panasonic G5 a Four Thirds sensor. The sensor area in the G5 is 74 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 2.0. The sensor in the 5D has a native 3:2 aspect ratio, while the one in the G5 offers a 4:3 aspect.

Despite having a smaller sensor, the G5 offers a higher resolution of 15.9 megapixels, compared with 12.7 MP of the 5D. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.76μm versus 8.25μm for the 5D). However, it should be noted that the G5 is much more recent (by 6 years and 11 months) than the 5D, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

The resolution advantage of the Panasonic G5 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G5 for good quality output (200 dots per inch) amounts to 23 x 17.3 inches or 58.5 x 43.9 cm, for very good quality (250 dpi) 18.4 x 13.8 inches or 46.8 x 35.1 cm, and for excellent quality (300 dpi) 15.4 x 11.5 inches or 39 x 29.3 cm. The corresponding values for the Canon 5D are 21.8 x 14.6 inches or 55.5 x 37 cm for good quality, 17.5 x 11.6 inches or 44.4 x 29.6 cm for very good quality, and 14.6 x 9.7 inches or 37 x 24.7 cm for excellent quality prints.

The Canon EOS 5D has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 50-3200. The corresponding ISO settings for the Panasonic Lumix DMC-G5 are ISO 160 to ISO 12800 (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.

For many cameras, data on sensor performance has been reported by DXO Mark. 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 review, the 5D has a notably higher overall DXO score than the G5 (overall score 10 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 1.5 bits higher color depth, 0.5 EV of lower 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 cannot only take still pictures, but also record videos. The G5 indeed provides for movie recording, while the 5D does not. The highest resolution format that the G5 can use is 1080/60p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the G5 has an electronic viewfinder (1440k dots), while the 5D 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 viewfinder in the G5 offers a wider field of view (100%) than the one in the 5D (96%), so that a larger proportion of the captured image is visible in the finder. On the other hand, the viewfinder of the 5D has a higher magnification (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 Canon 5D and Panasonic G5 in connection with corresponding information for a sample of similar cameras.

One feature that is present on the 5D, but is missing on the G5 is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.

The 5D writes its imaging data to Compact Flash cards, while the G5 uses SDXC 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 Canon EOS 5D and Panasonic Lumix DMC-G5 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Canon 5D (unlike the G5) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the 5D and the G5 have been discontinued, but can regularly be found used on ebay. The 5D was replaced by the Canon 5D Mark II, while the G5 was followed by the Panasonic G6. Further information on the features and operation of the 5D and G5 can be found, respectively, in the Canon 5D Manual (free pdf) or the online Panasonic G5 Manual.

Review summary

So how do things add up? Is the Canon 5D better than the Panasonic G5 or vice versa? Below is a summary of the relative strengths of each of the two contestants.

Advantages of the Canon EOS 5D:

• Better image quality: Scores markedly higher (10 points) in the DXO overall assessment.

If the count of relative strengths (bullet points above) is taken as a measure, the G5 is the clear winner of the contest (16 : 11 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 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 Canon 5D and the Panasonic G5 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Mirrorless Interchangeable Lens 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 partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the 5D or the G5. 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 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 are only valid when referring to cameras in the same category and of the same age. 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.
