Panasonic G85 versus Canon G1 X Mark III

The Panasonic Lumix DMC-G85 (called Panasonic G80 in some regions) and the Canon PowerShot G1 X Mark III are two digital cameras that were announced, respectively, in September 2016 and October 2017. The G85 is a mirrorless interchangeable lens camera, while the G1X Mark III is a fixed lens compact. The cameras are based on a Four Thirds (G85) and an APS-C (G1X Mark III) sensor. The Panasonic has a resolution of 15.8 megapixel, whereas the Canon provides 24 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 G85 vs Canon G1 X Mark III

An illustration of the physical size and weight of the Panasonic G85 and the Canon G1 X Mark III 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 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 side – the G85 – represents the basis for the calculations 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 G1 X Mark III is notably smaller (21 percent) than the Panasonic G85. 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 and possibly misleading, as the G1X Mark III has a lens build in, whereas the G85 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can find an overview of optics for the G85 and their specifications in the Micro Four Thirds Lens Catalog.

Concerning battery life, the G85 gets 330 shots out of its DMW-BLC12 battery, while the G1X Mark III can take 200 images on a single charge of its NB-13L power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

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. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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 G85 vs Canon G1 X Mark III

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 G85 features a Four Thirds sensor and the Canon G1 X Mark III an APS-C sensor. The sensor area in the G1X Mark III is 48 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 G85 has a native 4:3 aspect ratio, while the one in the G1X Mark III offers a 3:2 aspect.

Panasonic G85 and Canon G1 X Mark III sensor measures

With 24MP, the G1X Mark III offers a higher resolution than the G85 (15.8MP), but the G1X Mark III has marginally smaller individual pixels (pixel pitch of 3.72μm versus 3.77μm for the G85). Yet, the G1X Mark III is a somewhat more recent model (by 1 year) than the G85, 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 G85 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The reported shutter speed and shutter burst refer to the use of the mechanical shutter. In addition, the G85 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).

Both the G85 and the G1X Mark III write their imaging data to SDXC cards.

If the number of relative strengths (bullet points above) is taken as a guide, the G1X Mark III comes out slightly ahead of the G85 (9 : 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.

G85 08:09 G1X Mark III

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the G85 or the G1X Mark III handle or perform in practice. 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 following table reports the overall rankings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. 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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
