Nikon D750 versus Sony RX10 IV

The Nikon D750 and the Sony Cyber-shot DSC-RX10 IV are two enthusiast cameras that were announced, respectively, in September 2014 and September 2017. The D750 is a DSLR, while the RX10 IV is a fixed lens compact. The cameras are based on a full frame (D750) and an one-inch (RX10 IV) sensor. The Nikon has a resolution of 24.2 megapixel, whereas the Sony provides 20 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Nikon D750 vs Sony RX10 IV

The side-by-side display below illustrates the physical size and weight of the Nikon D750 and the Sony RX10 IV. 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 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 D750 – represents 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 Sony RX10 IV is notably smaller (22 percent) than the Nikon D750. 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 D750 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 D750 and their specifications in the Nikon Lens Catalog.

Concerning battery life, the D750 gets 1230 shots out of its EN-EL15 battery, while the RX10 IV can take 400 images on a single charge of its NP-FW50 power pack.

The camera’s price is obviously a critical decision-making factor. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The RX10 IV was launched at a lower price than the D750, despite having a lens build in. 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.

 

Sensor comparison: Nikon D750 vs Sony RX10 IV

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 associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Nikon D750 features a full frame sensor and the Sony RX10 IV an one-inch sensor. The sensor area in the RX10 IV is 87 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 2.7. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Nikon D750 and Sony RX10 IV sensor measures

With 24.2MP, the D750 offers a higher resolution than the RX10 IV (20MP), but the D750 nevertheless has larger individual pixels (pixel pitch of 5.97μm versus 2.41μm for the RX10 IV) due to its larger sensor. However, the RX10 IV is a somewhat more recent model (by 3 years) than the D750, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.

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 better video resolution than the D750. It can shoot movie footage at 4K/30p, while the Nikon is limited to 1080/60p.

 

Feature comparison: Nikon D750 vs Sony RX10 IV

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the RX10 IV has an electronic viewfinder (2359k dots), while the D750 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 following table reports on some other key feature differences and similarities of the Nikon D750, the Sony RX10 IV, and comparable cameras.

Both the D750 and the RX10 IV are current models that good online retailers will have in stock. You can check the latest prices, for example, at amazon. The D750 replaced the earlier Nikon D700, while the RX10 IV followed on from the Sony RX10 III.

Review summary: Nikon D750 vs Sony RX10 IV

So what is the bottom line? Is the Nikon D750 better than the Sony RX10 IV or vice versa? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Arguments in favor of the Nikon D750:

  • More detail: Offers more megapixels (24.2 vs 20MP) with a 10% higher linear resolution.
  • 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 (4000/sec vs 2000/sec) to freeze action.
  • More flexible: Can take a variety of interchangeable lenses, including specialty optics.
  • Longer lasting: Can take more shots (1230 versus 400) on a single battery charge.
  • More heavily discounted: Has been available for much longer (launched in September 2014).

ilogo

Reasons to prefer the Sony Cyber-shot DSC-RX10 IV:

  • 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).
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • Faster burst: Shoots at higher frequency (24 vs 6 flaps/sec) to capture the decisive moment.
  • Ready to shoot: Comes with an integrated lens, while the D750 requires a separate lens.
  • More compact: Is smaller (133x94mm vs 141x113mm) and will fit more readily into a bag.
  • Sharper images: Has stabilization technology build-in to reduce the impact of hand-shake.
  • More affordable: Was introduced at a lower price, despite coming with a build-in lens.
  • More modern: Reflects 3 years of technical progress since the D750 launch.

If the number of relative strengths (bullet points above) is taken as a guide, the RX10 IV emerges as the winner of the match-up (10 : 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.

D750 07:10 RX10 IV

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the D750 or the RX10 IV handle or perform in practice. 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 expert reviews are important. The adjacent table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

Care should be taken when interpreting the review scores above, though. The ratings are only valid when refering 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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
