Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon D3100 and the Nikon Z6? 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 D3100 and the Nikon Z6 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter.
The D3100 can be obtained in two different colors (black, red), while the Z6 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 Nikon Z6 is notably larger (14 percent) than the Nikon D3100. Moreover, the Z6 is markedly heavier (34 percent) than the D3100. It is noteworthy in this context that the Z6 is splash and dust-proof, while the D3100 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. Hence, you might want to study and compare the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.
Concerning battery life, the D3100 gets 550 shots out of its EN-EL14 battery, while the Z6 can take 310 images on a single charge of its EN-EL15b power pack. The power pack in the Z6 can be charged via the USB port, which can be very convenient when travelling.

Any camera decision will obviously take relative prices into account. 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 D3100 was launched at a markedly lower price (by 70 percent) than the Z6, 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.
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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to 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 D3100 features an APS-C sensor and the Nikon Z6 a full frame sensor. The sensor area in the Z6 is 141 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 Z6 uses a more advanced image processing engine (EXPEED 6) than the D3100 (EXPEED 2), with benefits for noise reduction, color accuracy, and processing speed.
With 24.3MP, the Z6 offers a higher resolution than the D3100 (14.2MP), but the Z6 nevertheless has larger individual pixels (pixel pitch of 5.94μm versus 5.01μm for the D3100) due to its larger sensor. Moreover, the Z6 is a much more recent model (by 8 years) than the D3100, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.
The resolution advantage of the Nikon Z6 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the Z6 for good quality output (200 dots per inch) amounts to 30.2 x 20.1 inch or 76.8 x 51.1 cm, for very good quality (250 dpi) 24.2 x 16.1 inch or 61.4 x 40.9 cm, and for excellent quality (300 dpi) 20.2 x 13.4 inch or 51.2 x 34.1 cm. The corresponding values for the Nikon D3100 are 23 x 15.4 inch or 58.5 x 39 cm for good quality, 18.4 x 12.3 inch or 46.8 x 31.2 cm for very good quality, and 15.4 x 10.2 inch or 39 x 26 cm for excellent quality prints.
The Z6 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Nikon D3100 has a native sensitivity range from ISO 100 to ISO 3200, which can be extended to ISO 100-12800. The corresponding ISO settings for the Nikon Z6 are ISO 100 to ISO 51200, with the possibility to increase the ISO range to 50-204800.
For many cameras, data on sensor performance has been reported by DXO Mark. 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 Z6 offers substantially better image quality than the D3100 (overall score 28 points higher). The advantage is based on 2.8 bits higher color depth, 3 EV in additional dynamic range, and 1.8 stops in additional low light sensitivity. 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 cannot only take still pictures, but also record videos. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the Z6 provides a better video resolution than the D3100. It can shoot movie footage at 4K/30p, while the D3100 is limited to 1080/24p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the Z6 has an electronic viewfinder (3690k dots), while the D3100 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 Z6 offers a wider field of view (100%) than the one in the D3100 (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the Z6 has a higher magnification (0.80x vs 0.53x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The adjacent table lists some of the other core features of the Nikon D3100 and Nikon Z6 along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The D3100 has one, while the Z6 does not. While the built-in flash of the D3100 is not very powerful, it can at times be useful as a fill-in light.
The Nikon Z6 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 D3100 writes its imaging data to SDXC cards, while the Z6 uses XQD 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 D3100 and Nikon Z6 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the Z6 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the D3100 does not offer wifi capability.
The Z6 is a recent model that features in the current product line-up of Nikon. In contrast, the D3100 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the D3100 was succeeded by the Nikon D3200. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Nikon website.

If the number of relative strengths (bullet points above) is taken as a guide, the Z6 is the clear winner of the contest (28 : 7 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 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 D3100 and the Nikon Z6 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 the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the D3100 and the Z6 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 where reviews by experts come in. 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.

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. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, 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.
