Sony RX10 IV versus Nikon D7100
The Sony Cyber-shot DSC-RX10 IV and the Nikon D7100 are two enthusiast cameras that were revealed to the public, respectively, in September 2017 and February 2013. The RX10 IV is a fixed lens compact, while the D7100 is a DSLR. The cameras are based on an one-inch (RX10 IV) and an APS-C sensor. The Sony has a resolution of 20 megapixel, whereas the Nikon provides 24 MP.
The side-by-side display below illustrates the physical size and weight of the Sony RX10 IV and the Nikon D7100. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth dimensions are rounded to the nearest millimeter. You can also toggle the display to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left – the RX10 IV – 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 D7100 is notably larger (16 percent) than the Sony RX10 IV. 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 and possibly misleading, as the RX10 IV has a lens build in, whereas the D7100 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can find an overview of optics for the D7100 and their specifications 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. 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 are more costly to manufacture and tent to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Sony RX10 IV features an one-inch sensor and the Nikon D7100 an APS-C sensor. The sensor area in the D7100 is 216 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
With 24MP, the D7100 offers a higher resolution than the RX10 IV (20MP), but the D7100 nevertheless has larger individual pixels (pixel pitch of 3.91μm versus 2.41μm for the RX10 IV) due to its larger sensor. However, the RX10 IV is a much more recent model (by 4 years and 6 months) than the D7100, 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 D7100 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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. 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 RX10 IV provides a higher video resolution than the D7100. It can shoot video footage at 4K/30p, while the Nikon is limited to 1080/60p.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the RX10 IV has an electronic viewfinder (2359k dots), while the D7100 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 adjacent table lists some of the other core features of the Sony RX10 IV and Nikon D7100 along with similar information for a selection of comparators.

The RX10 IV 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 conclusions can be drawn? Is the Sony RX10 IV better than the Nikon D7100 or vice versa? Below is a summary of the relative strengths of each of the two contestants.
Arguments in favor of the Sony Cyber-shot DSC-RX10 IV:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
- More framing info: Has an electronic viewfinder that displays shooting data.
- More detailed LCD: Has a higher resolution rear screen (1440k vs 1229k dots).
- More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
- Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
- Faster burst: Shoots at higher frequency (24 vs 6 flaps/sec) to capture the decisive moment.
- Ready to shoot: Comes with a build-in lens, while the D7100 requires a separate lens.
- More compact: Is smaller (133x94mm vs 136x107mm) and thus needs less room in the bag.
- More modern: Reflects 4 years and 6 months of technical progress since the D7100 launch.
Advantages of the Nikon D7100:
- More detail: Has more megapixels (24 vs 20MP), which boosts linear resolution by 10%.
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Brighter framing: Features an optical viewfinder for clear, lag-free composition.
- Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
- Faster shutter: Has higher mechanical shutter speed (8000/sec vs 2000/sec) to freeze action.
- More flexible: Makes it possible to change lenses and thus to use specialty optics.
- Longer lasting: Gets more shots (950 versus 400) out of a single battery charge.
- More heavily discounted: Has been around for much longer (launched in February 2013).
If the count of individual advantages (bullet points above) is taken as a guide, the RX10 IV emerges as the winner of the contest (10 : 8 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 partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the RX10 IV or the D7100. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable. This is why hands-on reviews by experts are important. The table below summarizes the assessments of some of the best known camera review sites.

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
