Panasonic GX8 versus Canon 1D X Mark II

The Panasonic Lumix DMC-GX8 and the Canon EOS-1D X Mark II are two digital cameras that were revealed to the public, respectively, in July 2015 and February 2016. The GX8 is a mirrorless interchangeable lens camera, while the 1DX Mark II is a DSLR. The cameras are based on a Four Thirds (GX8) and a full frame (1DX Mark II) sensor. The Panasonic has a resolution of 20.2 megapixel, whereas the Canon provides 20 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 GX8 vs Canon 1D X Mark II

The physical size and weight of the Panasonic GX8 and the Canon 1D X Mark II are illustrated 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. 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 GX8 – 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 1D X Mark II is considerably larger (156 percent) than the Panasonic GX8. Moreover, the 1DX Mark II is substantially heavier (214 percent) than the GX8. 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 Micro Four Thirds Lens Catalog (GX8) and the Canon EF Lens Catalog (1DX Mark II). Mirrorless cameras, such as the Panasonic GX8, 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 GX8 gets 330 shots out of its DMW-BLC12 battery, while the 1DX Mark II can take 1210 images on a single charge of its LP-E19 power pack. As can be seen in the images above, the 1DX Mark II has a battery grip build in. This facilitates image-taking in portrait orientation and gives it additional battery power.

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 GX8 was launched at a markedly lower price (by 80 percent) than the 1DX Mark II, 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 GX8 vs Canon 1D X Mark II

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and 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 Panasonic GX8 features a Four Thirds sensor and the Canon 1D X Mark II a full frame sensor. The sensor area in the 1DX Mark II 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 GX8 has a native 4:3 aspect ratio, while the one in the 1DX Mark II offers a 3:2 aspect.

Panasonic GX8 and Canon 1D X Mark II sensor measures

Despite having a smaller sensor, the Panasonic GX8 offers a higher resolution of 20.2 megapixel, compared with 20 MP of the Canon 1D X Mark II. 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 6.57μm for the 1DX Mark II). Moreover, it should be noted that the 1DX Mark II is a somewhat more recent model (by 6 months) than the GX8, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.

The 1DX Mark II has on-sensor phase detect pixels, which results in relatively fast and reliable autofocus acquisition during video recording.

GX8 versus 1DX Mark II 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 1DX Mark II offers substantially better image quality than the GX8 (overall score 13 points higher). The advantage is based on 0.6 bits higher color depth, 0.9 EV in additional dynamic range, and 2 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. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the 1DX Mark II provides a faster frame rate than the GX8. It can shoot movie footage at 4K/60p, while the Panasonic is limited to 4K/30p.

 

Feature comparison: Panasonic GX8 vs Canon 1D X Mark II

Beyond 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 1DX Mark II 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 table below summarizes some of the other core capabilities of the Panasonic GX8 and Canon 1D X Mark II in connection with corresponding information for a sample of similar cameras.

One feature that differentiates the GX8 and the 1DX Mark II is in-body image stabilization (IBIS). The GX8 reduces the risk of handshake-induced blur with all attached lenses, while the 1DX Mark II has to rely on optical image stabilization in OIS-equipped lenses to achieve the same effect.

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 GX8 writes its imaging data to SDXC cards, while the 1DX Mark II uses Compact Flash or CFast cards. The 1DX Mark II features dual card slots, which can be very useful in case a memory card fails. In contrast, the GX8 only has one slot.

  • More modern: Was introduced somewhat (6 months) more recently.

If the count of individual advantages (bullet points above) is taken as a guide, the 1DX Mark II is the clear winner of the contest (16 : 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.

GX8 11:16 1DX Mark II

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 GX8 or the 1DX Mark II handle or perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased. This is why expert reviews are important.

The above review scores should be interpreted with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. 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, please note that some of the review sites have changed their methodology and reporting over time.
