Nikon D7500 vs Panasonic G9
The Nikon D7500 and the Panasonic Lumix DC-G9 are two enthusiast cameras that were announced, respectively, in April 2017 and November 2017. The D7500 is a DSLR, while the G9 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (D7500) and a Four Thirds (G9) sensor. The Nikon has a resolution of 20.7 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 Nikon D7500 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.
The physical size and weight of the Nikon D7500 and the Panasonic G9 are illustrated 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 width, height and depth measures 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 (6 percent) than the Nikon D7500. Moreover, the G9 is markedly lighter (9 percent) than the D7500. 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 Nikon Lens Catalog (D7500) 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 D7500 gets 950 shots out of its EN-EL15a 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 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 D7500 was launched at a somewhat lower price (by 24 percent) than the G9, which makes it more attractive for photographers on a tight budget. 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.
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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Nikon D7500 features an APS-C sensor and the Panasonic G9 a Four Thirds sensor. The sensor area in the G9 is 39 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 2.0. The sensor in the D7500 has a native 3:2 aspect ratio, while the one in the G9 offers a 4:3 aspect.
Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.
With 20.7MP, the D7500 offers a slightly higher resolution than the G9 (20.2MP), but the D7500 nevertheless has larger individual pixels (pixel pitch of 4.22μm versus 3.34μm for the G9) due to its larger sensor. However, the G9 is a somewhat more recent model (by 6 months) than the D7500, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.
Unlike the D7500, 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 Nikon D7500 has a native sensitivity range from ISO 100 to ISO 51200, which can be extended to ISO 50-1640000. 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 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 also of capturing video footage. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the G9 provides a faster frame rate than the D7500. It can shoot movie footage at 4K/60p, while the Nikon is limited to 4K/30p.
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 D7500 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 D7500 (0.83x vs 0.61x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The following table reports on some other key feature differences and similarities of the Nikon D7500, the Panasonic G9, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The D7500 has one, while the G9 does not. While the built-in flash of the D7500 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 D7500 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 Nikon D7500 and the Panasonic G9 both have 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.
Concerning the storage of imaging data, both the D7500 and the G9 write their files to SDXC cards. The G9 features dual card slots, which can be very useful in case a memory card fails. In contrast, the D7500 only has one slot. The G9 supports UHS-II cards (on both slots), while the D7500 can use UHS-I cards.
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 Nikon D7500 and Panasonic Lumix DC-G9 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Panasonic G9 (unlike the D7500) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the D7500 and the G9 are recent models that are part of the current product line-up. The D7500 replaced the earlier Nikon D7200, while the G9 does not have a direct predecessor. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Nikon and Panasonic websites.
So what is the bottom line? Is the Nikon D7500 better than the Panasonic G9 or vice versa? Below is a summary of the relative strengths of each of the two contestants.
Arguments in favor of the Nikon D7500:
- Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.

If the number of relative strengths (bullet points above) is taken as a guide, the G9 is the clear winner of the contest (18 : 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. 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.
How about other alternatives? Do the specifications of the Nikon D7500 and the Panasonic G9 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Mirrorless Interchangeable Lens Camera listings whether the two cameras rank among the cream of the crop.
In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the D7500 or the G9 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 expert reviews are important. 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.

Care should be taken when interpreting the review scores above, 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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
