Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon D3X and the Nikon D780? 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.

Body comparison

An illustration of the physical size and weight of the Nikon D3X and the Nikon D780 is provided 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.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon D780 is considerably smaller (34 percent) than the Nikon D3X. Moreover, the D780 is markedly lighter (33 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. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can compare the optics available in the Nikon Lens Catalog.

Concerning battery life, the D3X gets 4400 shots out of its Nikon EN-EL4a battery, while the D780 can take 2260 images on a single charge of its Nikon EN-EL15b 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. The power pack in the D780 can be charged via the USB port, which can be very convenient when travelling.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

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 D780 was launched at a markedly lower price (by 71 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.

Sensor comparison

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. 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.

Both cameras under consideration feature a full frame sensor, but their sensors differ slightly in size. They nevertheless have the same format factor of 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Technology-wise, the D780 uses a more advanced image processing engine (EXPEED 6) than the D3X (EXPEED), with benefits for noise reduction, color accuracy, and processing speed.

With 24.4MP, the D3X offers a slightly higher resolution than the D780 (24.3MP), but the D3X nevertheless has the same individual pixel size (pixel pitch of 5.94μm) as the D780 due to its larger sensor. Moreover, the D780 is a much more recent model (by 11 years and 1 month) than the D3X, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels.

The D780 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

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 Nikon D780 are ISO 100 to ISO 51200, with the possibility to increase the ISO range to 50-204800.

In terms of underlying technology, the D3X is build around a CMOS sensor, while the D780 uses a BSI-CMOS imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

For many cameras, data on sensor performance has been reported by DXO Mark. 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.

Note: DXO values in italics represent estimates based on sensor size and age.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The D780 indeed provides for movie recording, while the D3X does not. The highest resolution format that the D780 can use is 4K/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The D3X and the D780 are similar in the sense that both have an optical viewfinder. The latter is useful for getting a clear image for framing even in brightly lit environments. The viewfinders of both cameras offer the same field of view (100%), as well as the same magnification (0.70x). The table below summarizes some of the other core capabilities of the Nikon D3X and Nikon D780 in connection with corresponding information for a sample of similar cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The D780 has a touchscreen, while the D3X has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The Nikon D3X and the Nikon D780 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 D780 uses SDXC cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails.

Connectivity comparison

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 Nikon D780 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the D780 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.

The D780 is a recent model that features in the current product line-up of Nikon. In contrast, the D3X has been discontinued (but can be found pre-owned on ebay). There has not been a direct replacement model for the D3X from Nikon. Further information on the features and operation of the D3X and D780 can be found, respectively, in the Nikon D3X Manual (free pdf) or the online Nikon D780 Manual.

Review summary

So what is the bottom line? Is there a clear favorite between the Nikon D3X and the Nikon D780? Which camera is better? The listing below highlights the relative strengths of the two models.

Reasons to prefer the Nikon D3X:

• More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
• Longer lasting: Can take more shots (4400 versus 2260) on a single battery charge.
• More heavily discounted: Has been available for much longer (launched in December 2008).

Advantages of the Nikon D780:

• Better jpgs: Has a more modern image processing engine (EXPEED 6 vs EXPEED).
• Broader imaging potential: Can capture not only stills but also 4K/30p video.
• Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
• Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (2359k vs 922k dots).
• More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
• Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
• Faster burst: Shoots at higher frequency (12 vs 5 flaps/sec) to capture the decisive moment.
• More compact: Is smaller (144x116mm vs 160x157mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 420g or 33 percent) and is thus easier to take along.
• Easier travel charging: Can be conveniently charged via its USB port.
• Faster data transfer: Supports a more advanced USB protocol (3.1 vs 2.0).
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• Easier wireless transfer: Supports Bluetooth for image sharing without cables.
• More affordable: Was introduced into a lower priced category (71 percent cheaper at launch).
• More modern: Reflects 11 years and 1 month of technical progress since the D3X launch.

If the number of relative strengths (bullet points above) is taken as a guide, the D780 is the clear winner of the contest (16 : 3 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 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 D3X and the Nikon D780 place the cameras among the top in their class? Find out in the latest Best DSLR Camera listing 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 says little about, for example, the shooting experience and imaging performance of the D3X and the D780 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.

Expert reviews

This is why hands-on reviews by experts are important. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], 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.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

The above review scores should be interpreted 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 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.
