Panasonic GX85 versus Canon 5D

The Panasonic Lumix DMC-GX85 (called Panasonic GX80 in some regions) and the Canon EOS 5D are two digital cameras that were revealed to the public, respectively, in April 2016 and August 2005. The GX85 is a mirrorless interchangeable lens camera, while the 5D is a DSLR. The cameras are based on a Four Thirds (GX85) and a full frame (5D) sensor. The Panasonic has a resolution of 15.8 megapixel, whereas the Canon provides 12.7 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: Panasonic GX85 vs Canon 5D

The physical size and weight of the Panasonic GX85 and the Canon 5D are illustrated in the side-by-side display below. 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 toggle the display 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 GX85 – 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 Canon 5D is considerably larger (98 percent) than the Panasonic GX85. Moreover, the 5D is substantially heavier (110 percent) than the GX85. It is noteworthy in this context that the 5D is splash and dust-proof, while the GX85 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 find an overview of optics for the two cameras in the Micro Four Thirds Lens Catalog (GX85) and the Canon EF Lens Catalog (5D). Mirrorless cameras, such as the Panasonic GX85, 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 GX85 gets 290 shots out of its DMW-BLG10 battery, while the 5D can take 400 images on a single charge of its BP-511A power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The GX85 was launched at a markedly lower price (by 76 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: Panasonic GX85 vs Canon 5D

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 tend to be more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Panasonic GX85 features a Four Thirds sensor and the Canon 5D a full frame sensor. The sensor area in the 5D 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 GX85 has a native 4:3 aspect ratio, while the one in the 5D offers a 3:2 aspect.

Panasonic GX85 and Canon 5D sensor measures
Sensor size

Despite having a smaller sensor, the Panasonic GX85 offers a higher resolution of 15.8 megapixel, compared with 12.7 MP of the Canon 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 3.77μm versus 8.25μm for the 5D). However, it should be noted that the GX85 is much more recent (by 10 years and 7 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. Coming back to sensor resolution, it should be mentioned that the GX85 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The GX85 indeed provides movie recording capabilities, while the 5D does not. The highest resolution format that the GX85 can use is 4K/30p.

Feature comparison: Panasonic GX85 vs Canon 5D

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the GX85 has an electronic viewfinder (2765k 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 Panasonic GX85, the Canon 5D, and comparable cameras.

The GX85 is a current model that online retailers, such as amazon, will have in stock. In contrast, the 5D has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the 5D was succeeded by the Canon 5D Mark II.

Review summary: Panasonic GX85 vs Canon 5D

So what conclusions can be drawn? Is there a clear favorite between the Panasonic GX85 and the Canon 5D? The listing below highlights the relative strengths of the two models.


logo checkmark

Reasons to prefer the Panasonic Lumix DMC-GX85:

  • More detail: Offers more megapixels (15.8 vs 12.7MP) with a 9% higher linear resolution.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • More dynamic range: Captures a larger spectrum of light and dark details (1.5 EV of extra DR).
  • Broader imaging potential: Can record not only still images but also 4K/30p movies.
  • More framing info: Has an electronic viewfinder that displays shooting data.
  • Larger screen: Has a bigger rear LCD (3.0" vs 2.5") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 230k dots).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
  • Faster burst: Shoots at higher frequency (8 vs 3 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (122x71mm vs 152x113mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 469g or 52 percent) and hence easier to carry around.
  • More legacy lens friendly: Can take a broad range of non-native lenses via adapters.
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
  • Sharper images: Has hand-shake reducing image stabilization build-in.
  • More affordable: Was introduced into a lower priced category (76 percent cheaper at launch).
  • More modern: Reflects 10 years and 7 months of technical progress since the 5D launch.

Arguments in favor of the Canon EOS 5D:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Better low-light sensitivity: Can shoot in dim conditions (1 stops ISO advantage).
  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • Easier setting verification: Has a control panel on top to check shooting parameters.
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • Longer lasting: Gets more shots (400 versus 290) out of a single battery charge.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • More heavily discounted: Has been around for much longer (launched in August 2005).

If the count of individual advantages (bullet points above) is taken as a guide, the GX85 is the clear winner of the match-up (17 : 8 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.

GX85 17:08 5D

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 handling experience and imaging performance when actually working with the GX85 or the 5D. 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. This is why hands-on reviews by experts are important. The adjacent table relays the overall verdicts of several of the most popular camera review sites. The full reviews are available, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. 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.
