Canon 5D versus Panasonic GX8

The Canon EOS 5D and the Panasonic Lumix DMC-GX8 are two digital cameras that were officially introduced, respectively, in August 2005 and July 2015. The 5D is a DSLR, while the GX8 is a mirrorless interchangeable lens camera. The cameras are based on a full frame (5D) and a Four Thirds (GX8) sensor. The Canon has a resolution of 12.7 megapixel, whereas the Panasonic provides 20.2 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Canon 5D vs Panasonic GX8

The side-by-side display below illustrates the physical size and weight of the Canon 5D and the Panasonic GX8. 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 dimensions are rounded to the nearest millimeter. You can also use the toggle button to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left – the 5D – represents 100 percent across all the size and weight measures).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic GX8 is considerably smaller (40 percent) than the Canon 5D. Moreover, the GX8 is substantially lighter (46 percent) than the 5D. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.

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 find an overview of optics for the two cameras in the Canon EF Lens Catalog (5D) and the Micro Four Thirds Lens Catalog (GX8). Mirrorless cameras, such as the GX8, 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 BP-511A battery, while the GX8 can take 330 images on a single charge of its DMW-BLC12 power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

Any camera purchase 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. The GX8 was launched at a markedly lower price (by 64 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.

 

Sensor comparison: Canon 5D vs Panasonic GX8

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. 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 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 GX8 a Four Thirds sensor. The sensor area in the GX8 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 GX8 offers a 4:3 aspect.

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

Canon 5D and Panasonic GX8 sensor measures

Despite having a smaller sensor, the GX8 offers a higher resolution of 20.2 megapixel, compared with 12.7 MP of the 5D. This megapixel advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.34μm versus 8.25μm for the 5D). However, it should be noted that the GX8 is much more recent (by 9 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.

5D versus GX8 MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 GX8 has a markedly higher DXO score than the 5D (overall score 4 points higher), which will translate into better image quality. The advantage is based on 0.6 bits higher color depth, 1.5 EV in additional dynamic range, 0.8 stops of reduced 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 are not only capable of taking still images, but also of capturing video footage. The GX8 indeed provides for movie recording, while the 5D does not. The highest resolution format that the GX8 can use is 4K/30p.

 

Feature comparison: Canon 5D vs Panasonic GX8

Apart from body and sensor, cameras can and do differ across a range of features. For example, the GX8 has an electronic viewfinder (2360k 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 following table reports on some other key feature differences and similarities of the Canon 5D, the Panasonic GX8, and comparable cameras.

One feature that is present on the 5D, but is missing on the GX8 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 reported shutter speed and shutter burst refer to the use of the mechanical shutter. In addition, the GX8 features an electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (rolling shutter) or shooting under artificial light sources (flickering).

The 5D writes its imaging data to Compact Flash cards, while the GX8 uses SDXC cards.

  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • More compact: Is smaller (133x78mm vs 152x113mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 408g or 46 percent) and is thus easier to take along.
  • Sharper images: Has stabilization technology build-in to reduce the impact of hand-shake.
  • More legacy lens friendly: Can use many non-native lenses via adapters.
  • Easier file upload: Has wifi build in for automatic backup or image transfer to the web.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • More affordable: Was introduced into a lower priced category (64 percent cheaper at launch).
  • More modern: Reflects 9 years and 11 months of technical progress since the 5D launch.

If the number of relative strengths (bullet points above) is taken as a guide, the GX8 is the clear winner of the contest (19 : 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.

5D 05:19 GX8

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the 5D or the GX8. 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 why expert reviews are important.

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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
