Canon 7D vs Panasonic G9
The Canon EOS 7D and the Panasonic Lumix DC-G9 are two enthusiast cameras that were officially introduced, respectively, in September 2009 and November 2017. The 7D is a DSLR, while the G9 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (7D) and a Four Thirds (G9) sensor. The Canon has a resolution of 17.9 megapixels, whereas the Panasonic provides 20.2 MP.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.
Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS 7D and the Panasonic Lumix DC-G9? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.
An illustration of the physical size and weight of the Canon 7D and the Panasonic G9 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic G9 is notably smaller (19 percent) than the Canon 7D. Moreover, the G9 is markedly lighter (23 percent) than the 7D. 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 compare the optics available for the two cameras in the Canon EF Lens Catalog (7D) and the Micro Four Thirds Lens Catalog (G9). Mirrorless cameras, such as the G9, 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 7D gets 800 shots out of its LP-E6 battery, while the G9 can take 400 images on a single charge of its DMW-BLF19 power pack. The power pack in the G9 can be charged via the USB port, which can be very convenient when travelling.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

Any camera decision 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. The two cameras under review were launched at the same price and fall into the same 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.
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. 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 Canon 7D features an APS-C sensor and the Panasonic G9 a Four Thirds sensor. The sensor area in the G9 is 32 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 2.0. The sensor in the 7D has a native 3:2 aspect ratio, while the one in the G9 offers a 4:3 aspect.
Despite having a smaller sensor, the G9 offers a higher resolution of 20.2 megapixels, compared with 17.9 MP of the 7D. This megapixels 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 4.31μm for the 7D). However, it should be noted that the G9 is much more recent (by 8 years and 2 months) than the 7D, 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 G9 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
Unlike the 7D, 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).
The Canon EOS 7D has a native sensitivity range from ISO 100 to ISO 6400, which can be extended to ISO 100-12800. The corresponding ISO settings for the Panasonic Lumix DC-G9 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.
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"). 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 G9 provides a better video resolution than the 7D. It can shoot movie footage at 4K/60p, while the Canon is limited to 1080/30p.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the G9 has an electronic viewfinder (3680k dots), while the 7D 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 viewfinders of both cameras offer the same field of view (100%), but the viewfinder of the G9 has a higher magnification than the one of the 7D (0.83x vs 0.63x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The adjacent table lists some of the other core features of the Canon 7D and Panasonic G9 along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The 7D has one, while the G9 does not. While the built-in flash of the 7D is not very powerful, it can at times be useful as a fill-in light.The G9 has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the 7D does not have a selfie-screen.
The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the G9 is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).
The Panasonic G9 has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.
The 7D writes its imaging data to Compact Flash cards, while the G9 uses SDXC cards. The G9 features dual card slots, which can be very useful in case a memory card fails. In contrast, the 7D only has one slot.
For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Canon EOS 7D and Panasonic Lumix DC-G9 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the G9 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the 7D does not provide wifi capability.
Both cameras feature a PC Sync terminal to control professional strobe lights, which will be appreciated by studio photographers.
The G9 is a recent model that features in the current product line-up of Panasonic. In contrast, the 7D has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the 7D was succeeded by the Canon 7D Mark II. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Panasonic websites.
So what conclusions can be drawn? Is there a clear favorite between the Canon 7D and the Panasonic G9? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.
Advantages of the Canon EOS 7D:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.

If the number of relative strengths (bullet points above) is taken as a guide, the G9 is the clear winner of the contest (24 : 5 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. A professional wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

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 7D or the G9 perform in practice. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.
This is where reviews by experts come in. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (amateurphotographer [AP], cameralabs [CL], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier point that a camera decision is often a very personal choice.

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. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, 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.
