Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon D3400 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

The side-by-side display below illustrates the physical size and weight of the Nikon D3400 and the Nikon D780. 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 size dimensions are rounded to the nearest millimeter.

The D3400 can be obtained in two different colors (black, red), while the D780 is only available in black.

Compare D3400 versus D780 top
Comparison D3400 or D780 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon D780 is notably larger (37 percent) than the Nikon D3400. Moreover, the D780 is substantially heavier (89 percent) than the D3400. It is noteworthy in this context that the D780 is splash and dust-proof, while the D3400 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 (as in the D780) will tend to go along with bigger and heavier lenses, while more compact options are available for the smaller-sensor camera (D3400). You can compare the optics available in the Nikon Lens Catalog.

The power pack in the D780 can be charged via the USB port, which can be very convenient when travelling.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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.

Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.

Any camera decision will naturally be influenced heavily by the price. 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 D3400 was launched at a markedly lower price (by 78 percent) than the D780, 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.

 

Sensor comparison

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 more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Nikon D3400 features an APS-C sensor and the Nikon D780 a full frame sensor. The sensor area in the D780 is 134 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 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 D3400 (EXPEED 4), with benefits for noise reduction, color accuracy, and processing speed.

Nikon D3400 and Nikon D780 sensor measures

With 24.3MP, the D780 offers a higher resolution than the D3400 (24MP), but the D780 nevertheless has larger individual pixels (pixel pitch of 5.94μm versus 3.91μm for the D3400) due to its larger sensor. Moreover, the D780 is a much more recent model (by 3 years and 4 months) than the D3400, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the D3400 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

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

The Nikon D3400 has a native sensitivity range from ISO 100 to ISO 25600. 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.

D3400 versus D780 MP

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").

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the D780 provides a better video resolution than the D3400. It can shoot movie footage at 4K/30p, while the D3400 is limited to 1080/60p.

 

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The D3400 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 viewfinder in the D780 offers a wider field of view (100%) than the one in the D3400 (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the D780 has a higher magnification (0.70x vs 0.57x), 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 D3400 and Nikon D780 in connection with corresponding information for a sample of similar cameras.

One difference between the cameras concerns the presence of an on-board flash. The D3400 has one, while the D780 does not. While the built-in flash of the D3400 is not very powerful, it can at times be useful as a fill-in light.

The Nikon D780 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.

Concerning the storage of imaging data, both the D3400 and the D780 write their files to SDXC cards. The D780 features dual card slots, which can be very useful in case a memory card fails. In contrast, the D3400 only has one slot. The D780 supports UHS-II cards (on both slots), while the D3400 can use UHS-I cards.

 

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 D3400 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 D3400 does not offer wifi capability.

Studio photographers will appreciate that the Nikon D780 (unlike the D3400) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

The D780 is a recent model that features in the current product line-up of Nikon. In contrast, the D3400 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the D3400 was succeeded by the Nikon D3500. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Nikon website.

Review summary

So how do things add up? Is the Nikon D3400 better than the Nikon D780 or vice versa? Below is a summary of the relative strengths of each of the two contestants.


Advantages of the Nikon D3400:

  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
  • Faster buffer clearing: Supports a more advanced SD data transfer standard (UHS-II vs UHS-I).
  • More modern: Reflects 3 years and 4 months of technical progress since the D3400 launch.

If the count of relative strengths (bullet points above) is taken as a measure, the D780 is the clear winner of the contest (28 : 6 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.

How about other alternatives? Do the specifications of the Nikon D3400 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 the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the D3400 or the D780. 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 (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.

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

Care should be taken when interpreting the review scores above, though. The ratings are only valid when referring to cameras in the same category and of the same age. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
