Nikon D7100 versus Nikon D850
The Nikon D7100 and the Nikon D850 are two digital cameras that were revealed to the public, respectively, in February 2013 and July 2017. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (D7100) and a full frame sensor. The D7100 has a resolution of 24 megapixel, whereas the D850 provides 45.4 MP.
The side-by-side display below illustrates the physical size and weight of the Nikon D7100 and the Nikon D850. Three consecutive perspectives from the front, the top, and the back are presented. All width, height and depth measures are rounded to the nearest millimeter. If you prefer, you can also use the toggle button to switch to a comparison in percentage terms (in this case, the camera on the left – the D7100 – represents the basis or 100 percent across all the size and weight measures).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon D850 is notably larger (24 percent) than the Nikon D7100. Moreover, the D850 is markedly heavier (31 percent) than the D7100. Cameras that are intended for semi-professional or professional use are sometimes a bit bulkier in order to provide them with the necessary ruggedness. 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 (as in the D850) will tend to go along with bigger and heavier lenses, while more compact options are available for the smaller-sensor camera (D7100). You can find a comprehensive overview of suitable optics in the Nikon Lens Catalog.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible comparisons there.

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The D7100 was launched at a markedly lower price (by 64 percent) than the D850, 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 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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its 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 D7100 features an APS-C sensor and the Nikon D850 a full frame sensor. The sensor area in the D850 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.
With 45.4MP, the D850 offers a higher resolution than the D7100 (24MP), but the D850 nevertheless has larger individual pixels (pixel pitch of 4.35μm versus 3.92μm for the D7100) due to its larger sensor. Moreover, the D850 is a much more recent model (by 4 years and 5 months) than the D7100, 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 neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.
For most 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 D850 offers substantially better image quality than the D7100 (overall score 17 points higher). The advantage is based on 2.2 bits higher color depth, 1.1 EV in additional dynamic range, and 1.1 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar 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 D850 provides a better video resolution than the D7100. It can shoot movie footage at 4K/30p, while the D7100 is limited to 1080/60p.
Apart from body and sensor, cameras can and do differ across a variety of features. The D7100 and the D850 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 table below summarizes some of the other core capabilities of the Nikon D7100 and Nikon D850 in connection with corresponding information for a sample of similar cameras. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

The D850 is a current model that online retailers, such as amazon, will have in stock. In contrast, the D7100 has been discontinued (but it can be found pre-owned on ebay). As a replacement in the same line of cameras, the D7100 was succeeded by the Nikon D7200.
So what is the bottom line? Which of the two cameras – the Nikon D7100 or the Nikon D850 – has the upper hand? The listing below highlights the relative strengths of the two models.
Arguments in favor of the Nikon D7100:
- More compact: Is smaller (136x107mm vs 146x124mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 240g or 24 percent) and hence easier to carry around.
- Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
- More affordable: Was introduced into a lower priced category (64 percent cheaper at launch).
- More heavily discounted: Has been available for much longer (launched in February 2013).
Reasons to prefer the Nikon D850:
- More detail: Has more megapixels (45.4 vs 24MP), which boosts linear resolution by 38%.
- Better image quality: Scores substantially higher (17 points) in the DXO overall evaluation.
- Richer colors: Generates noticeably more natural colors (2.2 bits more color depth).
- More dynamic range: Captures a broader range of light and dark details (1.1 EV of extra DR).
- Better low-light sensitivity: Can shoot in dim conditions (1.1 stops ISO advantage).
- Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
- More detailed LCD: Has a higher resolution rear screen (2359k vs 1229k 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 (9 vs 6 flaps/sec) to capture the decisive moment.
- Longer lasting: Gets more shots (1840 versus 950) out of a single battery charge.
- More modern: Reflects 4 years and 5 months of technical progress since the D7100 launch.
If the number of relative strengths (bullet points above) is taken as a guide, the D850 is the clear winner of the contest (12 : 5 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.
In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the D7100 or the D850 handle or perform in practice. 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 following table reports the overall rankings of the cameras as published by some of the major camera review sites. The detailed reviews can be accessed, respectively, on the websites of cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

The review scores listed above should be treated with care, though. The ratings are only valid when refering 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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
