Nikon D3X vs Panasonic GH3
The Nikon D3X and the Panasonic Lumix DMC-GH3 are two digital cameras that were revealed to the public, respectively, in December 2008 and September 2012. The D3X is a DSLR, while the GH3 is a mirrorless interchangeable lens camera. The cameras are based on a full frame (D3X) and a Four Thirds (GH3) sensor. The Nikon has a resolution of 24.4 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 D3X and the Panasonic Lumix DMC-GH3? 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 D3X and the Panasonic GH3. 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.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic GH3 is considerably smaller (51 percent) than the Nikon D3X. Moreover, the GH3 is substantially lighter (56 percent) than the D3X. 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 (D3X) and the Micro Four Thirds Lens Catalog (GH3). Mirrorless cameras, such as the GH3, 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 D3X gets 4400 shots out of its EN-EL4a battery, while the GH3 can take 540 images on a single charge of its DMW-BLF19 power pack. As can be seen in the images above, the D3X has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power. In order to provide similar functionality for the GH3, Panasonic provides the DMW-BGGH3 vertical grip as an optional accessory (see here on eBay).

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 GH3 was launched at a markedly lower price (by 84 percent) than the D3X, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
The size of the imaging sensor is a crucial determinant of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units 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 more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Nikon D3X features a full frame sensor and the Panasonic GH3 a Four Thirds sensor. The sensor area in the GH3 is 74 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 2.0. The sensor in the D3X has a native 3:2 aspect ratio, while the one in the GH3 offers a 4:3 aspect.
In terms of underlying technology, both cameras are build around CMOS sensors.
With 24.4MP, the D3X offers a higher resolution than the GH3 (15.9MP), but the D3X nevertheless has larger individual pixels (pixel pitch of 5.94μm versus 3.76μm for the GH3) due to its larger sensor. However, the GH3 is a much more recent model (by 3 years and 9 months) than the D3X, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.
The resolution advantage of the Nikon D3X implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D3X for good quality output (200 dots per inch) amounts to 30.2 x 20.2 inches or 76.8 x 51.2 cm, for very good quality (250 dpi) 24.2 x 16.1 inches or 61.4 x 41 cm, and for excellent quality (300 dpi) 20.2 x 13.4 inches or 51.2 x 34.1 cm. The corresponding values for the Panasonic GH3 are 23 x 17.3 inches or 58.5 x 43.9 cm for good quality, 18.4 x 13.8 inches or 46.8 x 35.1 cm for very good quality, and 15.4 x 11.5 inches or 39 x 29.3 cm for excellent quality prints.
The Nikon D3X has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 50-6400. The corresponding ISO settings for the Panasonic Lumix DMC-GH3 are ISO 200 to ISO 12800, with the possibility to increase the ISO range to 125-25600.
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"). Of the two cameras under review, the D3X provides substantially higher image quality than the GH3, with an overall score that is 17 points higher. This advantage is based on 2 bits higher color depth, 1.3 EV in additional dynamic range, and 1.3 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 are not only capable of taking still images, but also of capturing video footage. The GH3 indeed provides for movie recording, while the D3X does not. The highest resolution format that the GH3 can use is 1080/60p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the GH3 has an electronic viewfinder (1746k dots), while the D3X 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 D3X has a higher magnification than the one of the GH3 (0.70x vs 0.67x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Nikon D3X and Panasonic GH3 in connection with corresponding information for a sample of similar cameras.
|Canon 1Ds Mark III||optical||Y||3.0||230||fixed||n||1/8000s||5.0||n||n|
|Olympus E-M5 II||2360||n||3.0||1037||swivel||Y||1/8000s||10.0||n||Y|
One feature that is present on the D3X, but is missing on the GH3 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 GH3 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 D3X does not have a selfie-screen.
The Nikon D3X and the Panasonic GH3 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.
The D3X writes its imaging data to Compact Flash cards, while the GH3 uses SDXC cards. The D3X features dual card slots, which can be very useful in case a memory card fails. In contrast, the GH3 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 Nikon D3X and Panasonic Lumix DMC-GH3 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

|Canon 1Ds Mark III||Y||-||-||-||-||-||2.0||-||-||-|
|Olympus E-M5 II||Y||stereo||mono||Y||-||micro||2.0||Y||-||-|
It is notable that the GH3 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the D3X does not provide wifi capability.
Both cameras feature a PC Sync terminal to control professional strobe lights, which will be appreciated by studio photographers.
Both the D3X and the GH3 have been discontinued, but can regularly be found used on eBay. The GH3 was replaced by the Panasonic GH4, while the D3X does not have a direct successor. 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.

If the count of relative strengths (bullet points above) is taken as a measure, the D3X comes out slightly ahead of the GH3 (14 : 13 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape 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 D3X and the Panasonic GH3 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 says little about, for example, the shooting experience and imaging performance of the D3X and the GH3 in practical situations. 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 (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 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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
