Nikon D40X vs Panasonic GH4
The Nikon D40X and the Panasonic Lumix DMC-GH4 are two digital cameras that were officially introduced, respectively, in March 2007 and February 2014. The D40X is a DSLR, while the GH4 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (D40X) and a Four Thirds (GH4) sensor. The Nikon has a resolution of 10 megapixels, whereas the Panasonic provides 15.9 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 D40X and the Panasonic Lumix DMC-GH4? 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 side-by-side display below illustrates the physical size and weight of the Nikon D40X and the Panasonic GH4. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth measures are rounded to the nearest millimeter.
The D40X can be obtained in two different colors (black, silver), while the GH4 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 GH4 is notably larger (6 percent) than the Nikon D40X. Moreover, the GH4 is markedly heavier (7 percent) than the D40X. It is noteworthy in this context that the GH4 is splash and dust-proof, while the D40X 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 (D40X) and the Micro Four Thirds Lens Catalog (GH4). Mirrorless cameras, such as the GH4, 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.

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 D40X was launched at a markedly lower price (by 51 percent) than the GH4, 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.
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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Nikon D40X features an APS-C sensor and the Panasonic GH4 a Four Thirds sensor. The sensor area in the GH4 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 D40X has a native 3:2 aspect ratio, while the one in the GH4 offers a 4:3 aspect.
Despite having a smaller sensor, the GH4 offers a higher resolution of 15.9 megapixels, compared with 10 MP of the D40X. 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 3.76μm versus 6.11μm for the D40X). However, it should be noted that the GH4 is much more recent (by 6 years and 11 months) than the D40X, 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 GH4 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GH4 for good quality output (200 dots per inch) amounts to 23 x 17.3 inch or 58.5 x 43.9 cm, for very good quality (250 dpi) 18.4 x 13.8 inch or 46.8 x 35.1 cm, and for excellent quality (300 dpi) 15.4 x 11.5 inch or 39 x 29.3 cm. The corresponding values for the Nikon D40X are 19.4 x 13 inch or 49.2 x 32.9 cm for good quality, 15.5 x 10.4 inch or 39.3 x 26.3 cm for very good quality, and 12.9 x 8.6 inch or 32.8 x 21.9 cm for excellent quality prints.
The Nikon D40X has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 100-3200. The corresponding ISO settings for the Panasonic Lumix DMC-GH4 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 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. Of the two cameras under consideration, the GH4 offers substantially better image quality than the D40X (overall score 11 points higher). The advantage is based on 0.8 bits higher color depth, 1.4 EV in additional dynamic range, and 0.6 stops in additional low light sensitivity. 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 cannot only take still pictures, but also record videos. The GH4 indeed provides for movie recording, while the D40X does not. The highest resolution format that the GH4 can use is 4K/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the GH4 has an electronic viewfinder (2359k dots), while the D40X 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 viewfinder in the GH4 offers a wider field of view (100%) than the one in the D40X (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the GH4 has a higher magnification (0.67x vs 0.53x), 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 D40X, the Panasonic GH4, and comparable cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The GH4 has a touchscreen, while the D40X has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The GH4 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 D40X 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 GH4 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 GH4 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 D40X writes its imaging data to SDHC cards, while the GH4 uses SDXC cards. The GH4 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the D40X cannot take advantage of Ultra High Speed SD 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 D40X and Panasonic Lumix DMC-GH4 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the GH4 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the D40X does not offer wifi capability.
Studio photographers will appreciate that the Panasonic GH4 (unlike the D40X) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the D40X and the GH4 have been discontinued, but can regularly be found used on eBay. The D40X was replaced by the Nikon D60 , while the GH4 was followed by the Panasonic GH5. 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? Which of the two cameras – the Nikon D40X or the Panasonic GH4 – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.
Arguments in favor of the Nikon D40X:

If the count of individual advantages (bullet points above) is taken as a guide, the GH4 is the clear winner of the contest (24 : 3 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision on a new camera. A professional wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro 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 D40X and the Panasonic GH4 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 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 D40X or the GH4 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 why expert reviews are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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 assessments were made in relation to similar cameras of the same technological generation. 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.
