Canon 1D X Mark II versus Panasonic G7

The Canon EOS-1D X Mark II and the Panasonic Lumix DMC-G7 are two digital cameras that were officially introduced, respectively, in February 2016 and May 2015. The 1DX Mark II is a DSLR, while the G7 is a mirrorless interchangeable lens camera. The cameras are based on a full frame (1DX Mark II) and a Four Thirds (G7) sensor. The Canon has a resolution of 20 megapixel, whereas the Panasonic provides 15.8 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 1D X Mark II vs Panasonic G7

The physical size and weight of the Canon 1D X Mark II and the Panasonic G7 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 1DX Mark II – 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 G7 is considerably smaller (60 percent) than the Canon 1D X Mark II. Moreover, the G7 is substantially lighter (73 percent) than the 1DX Mark II. It is worth mentioning in this context that the 1DX Mark II is splash and dust resistant, while the G7 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 Canon EF Lens Catalog (1DX Mark II) and the Micro Four Thirds Lens Catalog (G7). Mirrorless cameras, such as the G7, 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 1DX Mark II gets 1210 shots out of its LP-E19 battery, while the G7 can take 350 images on a single charge of its DMW-BLC12 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 following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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 camera’s price is obviously a critical decision-making factor. 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 G7 was launched at a markedly lower price (by 89 percent) than the 1DX Mark II, which puts it into a different market segment. 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: Canon 1D X Mark II vs Panasonic G7

The size of the imaging sensor is a crucial determinant 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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its 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 Canon 1D X Mark II features a full frame sensor and the Panasonic G7 a Four Thirds sensor. The sensor area in the G7 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 1DX Mark II has a native 3:2 aspect ratio, while the one in the G7 offers a 4:3 aspect.

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

Canon 1D X Mark II and Panasonic G7 sensor measures

With 20MP, the 1DX Mark II offers a higher resolution than the G7 (15.8MP), but the 1DX Mark II nevertheless has larger individual pixels (pixel pitch of 6.57μm versus 3.77μm for the G7) due to its larger sensor. Moreover, the 1DX Mark II is a somewhat more recent model (by 8 months) than the G7, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.

1DX Mark II versus G7 MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). 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 can also record movies. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the 1DX Mark II provides a higher frame rate than the G7. It can shoot video footage at 4K/60p, while the Panasonic is limited to 4K/30p.

 

Feature comparison: Canon 1D X Mark II vs Panasonic G7

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the G7 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 adjacent table lists some of the other core features of the Canon 1D X Mark II and Panasonic G7 along with similar information for a selection of comparators. The full specs-sheets can be found in the camera manual or in the dpreview camera hub.

One feature that is present on the 1DX Mark II, but is missing on the G7 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 G7 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 1DX Mark II writes its imaging data to Compact Flash or CFast cards, while the G7 uses SDXC cards. The 1DX Mark II features dual card slots, which can be very useful in case a memory card fails. In contrast, the G7 only has one slot.

If the count of relative strengths (bullet points above) is taken as a measure, the 1DX Mark II is the clear winner of the match-up (19 : 10 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.

1DX Mark II 19:10 G7

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 1DX Mark II or the G7. 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 where reviews by experts come in. 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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
