Nikon D7500 versus Panasonic G9

The Nikon D7500 and the Panasonic Lumix DC-G9 are two enthusiast cameras that were officially introduced, 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 megapixel, whereas the Panasonic provides 20.2 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: Nikon D7500 vs Panasonic G9

The side-by-side display below illustrates the physical size and weight of the Nikon D7500 and the Panasonic G9. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth 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 D7500 – 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 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 find an overview of optics 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 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 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. 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: Nikon D7500 vs Panasonic G9

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. 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 tend to be associated with larger, more expensive camera bodies 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.

Nikon D7500 and Panasonic G9 sensor measures

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 the G9 has no anti-alias filter installed, so that it can capture all the detail its 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).

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 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.

 

Feature comparison: Nikon D7500 vs Panasonic G9

Apart from 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 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 adjacent table lists some of the other core features of the Nikon D7500 and Panasonic G9 along with similar information for a selection of comparators. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

  • More framing info: Has an electronic viewfinder that displays shooting data.
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 922k dots).
  • More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
  • Faster burst: Shoots at higher frequency (20 vs 8 flaps/sec) to capture the decisive moment.
  • More legacy lens friendly: Can use many non-native lenses via adapters.
  • Sharper images: Has stabilization technology build-in to reduce the impact of hand-shake.
  • More modern: Was introduced somewhat (6 months) more recently.

If the count of relative strengths (bullet points above) is taken as a measure, the G9 emerges as the winner of the match-up (10 : 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 technical specifications can provide a useful overview of the capabilities of different cameras, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the D7500 and the G9 in practical situations. 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 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 ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, 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.
