Nikon D5100 vs Z7 II
The Nikon D5100 and the Nikon Z7 II are two digital cameras that were officially introduced, respectively, in April 2011 and October 2020. The D5100 is a DSLR, while the Z7 II is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (D5100) and a full frame (Z7 II) sensor. The D5100 has a resolution of 16.1 megapixels, whereas the Z7 II provides 45.4 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 D5100 and the Nikon Z7 II? 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 D5100 and the Nikon Z7 II. 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 Z7 II is notably larger (9 percent) than the Nikon D5100. Moreover, the Z7 II is markedly heavier (26 percent) than the D5100. It is noteworthy in this context that the Z7 II is splash and dust-proof, while the D5100 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 D5100 gets 660 shots out of its EN-EL14 battery, while the Z7 II can take 420 images on a single charge of its EN-EL15c power pack. The power pack in the Z7 II 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 would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

Any camera decision will obviously take relative prices into account. 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 D5100 was launched at a markedly lower price (by 75 percent) than the Z7 II, 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.
The size of the sensor inside a digital camera is one of the key determinants 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. 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Nikon D5100 features an APS-C sensor and the Nikon Z7 II a full frame sensor. The sensor area in the Z7 II is 131 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.
With 45.4MP, the Z7 II offers a higher resolution than the D5100 (16.1MP), but the Z7 II has smaller individual pixels (pixel pitch of 4.35μm versus 4.80μm for the D5100). Yet, the Z7 II is a much more recent model (by 9 years and 6 months) than the D5100, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the Z7 II has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Nikon Z7 II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the Z7 II for good quality output (200 dots per inch) amounts to 41.3 x 27.5 inches or 104.9 x 69.9 cm, for very good quality (250 dpi) 33 x 22 inches or 83.9 x 55.9 cm, and for excellent quality (300 dpi) 27.5 x 18.3 inches or 69.9 x 46.6 cm. The corresponding values for the Nikon D5100 are 24.6 x 16.3 inches or 62.6 x 41.5 cm for good quality, 19.7 x 13.1 inches or 50.1 x 33.2 cm for very good quality, and 16.4 x 10.9 inches or 41.7 x 27.6 cm for excellent quality prints.
The Z7 II has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Nikon D5100 has a native sensitivity range from ISO 100 to ISO 6400, which can be extended to ISO 100-25600. The corresponding ISO settings for the Nikon Z7 II are ISO 64 to ISO 25600, with the possibility to increase the ISO range to 32-102400.
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 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 are equipped with sensors that have a sufficiently high read-out speed for moving images, but the Z7 II provides a better video resolution than the D5100. It can shoot movie footage at 4K/60p, while the D5100 is limited to 1080/30p.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the Z7 II has an electronic viewfinder (3690k dots), while the D5100 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 Z7 II offers a wider field of view (100%) than the one in the D5100 (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the Z7 II has a higher magnification (0.80x vs 0.51x), 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 D5100, the Nikon Z7 II, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The D5100 has one, while the Z7 II does not. While the built-in flash of the D5100 is not very powerful, it can at times be useful as a fill-in light.The D5100 has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the Z7 II 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 Z7 II 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 Nikon D5100 and the Nikon Z7 II 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 D5100 writes its imaging data to SDXC cards, while the Z7 II uses CFexpress or SDXC cards. The Z7 II features dual card slots, which can be very useful in case a memory card fails. In contrast, the D5100 only has one slot. The Z7 II supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the D5100 can use UHS-I cards (up to 104 MB/s).
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 D5100 and Nikon Z7 II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the Z7 II offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the D5100 does not provide wifi capability.
The Z7 II is a recent model that features in the current product line-up of Nikon. In contrast, the D5100 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the D5100 was succeeded by the Nikon D5200. 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 count of relative strengths (bullet points above) is taken as a measure, the Z7 II is the clear winner of the contest (29 : 9 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding 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 D5100 and the Nikon Z7 II 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 D5100 and the Z7 II 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.
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], 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.

Care should be taken when interpreting the review scores above, 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.
