Panasonic G9 versus Canon 5D Mark IV
The Panasonic Lumix DC-G9 and the Canon EOS 5D Mark IV are two digital cameras that were revealed to the public, respectively, in November 2017 and August 2016. The G9 is a mirrorless interchangeable lens camera, while the 5D Mark IV is a DSLR. The cameras are based on a Four Thirds (G9) and a full frame (5D Mark IV) sensor. The Panasonic has a resolution of 20.2 megapixel, whereas the Canon provides 30.1 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 G9 vs Canon 5D Mark IV
The physical size and weight of the Panasonic G9 and the Canon 5D Mark IV 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 measures are rounded to the nearest millimeter. If you prefer, you can also use the toggle button to switch to a comparison in percentage terms (in this case, the camera on the left side – the G9 – 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 5D Mark IV is notably larger (32 percent) than the Panasonic G9. Moreover, the 5D Mark IV is substantially heavier (35 percent) than the G9. 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 (G9) and the Canon EF Lens Catalog (5D Mark IV). Mirrorless cameras, such as the Panasonic G9, 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.
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 G9 was launched at a markedly lower price (by 51 percent) than the 5D Mark IV, 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 G9 vs Canon 5D Mark IV
The size of the sensor inside a digital camera is one of the key determinants 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. 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 Panasonic G9 features a Four Thirds sensor and the Canon 5D Mark IV a full frame sensor. The sensor area in the 5D Mark IV 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 G9 has a native 4:3 aspect ratio, while the one in the 5D Mark IV offers a 3:2 aspect.
With 30.1MP, the 5D Mark IV offers a higher resolution than the G9 (20.2MP), but the 5D Mark IV nevertheless has larger individual pixels (pixel pitch of 5.36μm versus 3.34μm for the G9) due to its larger sensor. However, the G9 is a somewhat more recent model (by 1 year and 2 months) than the 5D Mark IV, 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 G9 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
Unlike the 5D Mark IV, the G9 has the capacity to capture high quality composite images (80.6MP) by combining multiple shots after shifting its sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).
For most cameras, data on sensor performance has been reported by DXO Mark. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

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 G9 provides a higher frame rate than the 5D Mark IV. It can shoot video footage at 4K/60p, while the Canon is limited to 4K/30p.
Feature comparison: Panasonic G9 vs Canon 5D Mark IV
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the G9 has an electronic viewfinder (3680k dots), while the 5D Mark IV 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 G9, the Canon 5D Mark IV, and comparable cameras. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

If the number of relative strengths (bullet points above) is taken as a guide, the G9 is the clear winner of the match-up (12 : 8 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision.
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 G9 or the 5D Mark IV. 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).

Care should be taken when interpreting the review scores above, though. The ratings are only valid when refering 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.
