Nikon D2X vs Panasonic GF7
The Nikon D2X and the Panasonic Lumix DMC-GF7 are two digital cameras that were announced, respectively, in September 2004 and January 2015. The D2X is a DSLR, while the GF7 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (D2X) and a Four Thirds (GF7) sensor. The Nikon has a resolution of 12.2 megapixels, whereas the Panasonic provides 15.8 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 D2X and the Panasonic Lumix DMC-GF7? 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 D2X and the Panasonic GF7 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 width, height and depth measures are rounded to the nearest millimeter.
The GF7 can be obtained in two different colors (black, pink), while the D2X is only available in black.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic GF7 is considerably smaller (71 percent) than the Nikon D2X. Moreover, the GF7 is substantially lighter (79 percent) than the D2X. It is worth mentioning in this context that the D2X is splash and dust resistant, while the GF7 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 compare the optics available for the two cameras in the Nikon Lens Catalog (D2X) and the Micro Four Thirds Lens Catalog (GF7). Mirrorless cameras, such as the GF7, 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 D2X gets 3800 shots out of its EN-EL4a battery, while the GF7 can take 230 images on a single charge of its DMW-BLH7 power pack. As can be seen in the images above, the D2X has a battery grip built 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. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

The price is, of course, an important factor in any camera decision. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The GF7 was launched at a markedly lower price (by 90 percent) than the D2X, 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.
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 Nikon D2X features an APS-C sensor and the Panasonic GF7 a Four Thirds sensor. The sensor area in the GF7 is 40 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 D2X has a native 3:2 aspect ratio, while the one in the GF7 offers a 4:3 aspect.
In terms of underlying technology, both cameras are build around CMOS sensors.
Despite having a smaller sensor, the GF7 offers a higher resolution of 15.8 megapixels, compared with 12.2 MP of the D2X. 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 3.77μm versus 5.52μm for the D2X). However, it should be noted that the GF7 is much more recent (by 10 years and 4 months) than the D2X, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.
The resolution advantage of the Panasonic GF7 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GF7 for good quality output (200 dots per inch) amounts to 23 x 17.2 inches or 58.3 x 43.8 cm, for very good quality (250 dpi) 18.4 x 13.8 inches or 46.7 x 35 cm, and for excellent quality (300 dpi) 15.3 x 11.5 inches or 38.9 x 29.2 cm. The corresponding values for the Nikon D2X are 21.4 x 14.2 inches or 54.5 x 36.2 cm for good quality, 17.2 x 11.4 inches or 43.6 x 28.9 cm for very good quality, and 14.3 x 9.5 inches or 36.3 x 24.1 cm for excellent quality prints.
The Nikon D2X has a native sensitivity range from ISO 100 to ISO 800, which can be extended to ISO 100-3200. The corresponding ISO settings for the Panasonic Lumix DMC-GF7 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 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 also of capturing video footage. The GF7 indeed provides for movie recording, while the D2X does not. The highest resolution format that the GF7 can use is 1080/60p.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the D2X has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the GF7 relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Nikon D2X, the Panasonic GF7, and comparable cameras.

One feature that is present on the D2X, but is missing on the GF7 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 GF7 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 D2X 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 GF7 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 D2X writes its imaging data to Compact Flash cards, while the GF7 uses SDXC 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 D2X and Panasonic Lumix DMC-GF7 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the D2X has a hotshoe, while the GF7 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.
Studio photographers will appreciate that the Nikon D2X (unlike the GF7) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the D2X and the GF7 have been discontinued, but can regularly be found used on eBay. The D2X was replaced by the Nikon D2Xs, while the GF7 was followed by the Panasonic GX850. 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 conclusions can be drawn? Is there a clear favorite between the Nikon D2X and the Panasonic GF7? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.
Reasons to prefer the Nikon D2X:
- Easier framing: Has an optical viewfinder for image composition and settings control.

If the count of relative strengths (bullet points above) is taken as a measure, the GF7 is the clear winner of the contest (17 : 9 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. 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 D2X or the GF7 perform in practice. 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 why hands-on reviews by experts are important. The following table reports the overall ratings of the cameras as published by some of the major 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 review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
