Sony A7 II versus Nikon D7500

The Sony Alpha A7 II and the Nikon D7500 are two enthusiast cameras that were officially introduced, respectively, in November 2014 and April 2017. The A7 II is a mirrorless interchangeable lens camera, while the D7500 is a DSLR. The cameras are based on a full frame (A7 II) and an APS-C sensor. The Sony has a resolution of 24 megapixel, whereas the Nikon provides 20.7 MP.

Body comparison

An illustration of the physical size and weight of the Sony A7 II and the Nikon D7500 is provided in the side-by-side display below. Three consecutive perspectives from the front, the top, and the back are presented. All size dimensions 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 side – the A7 II – represents the basis for the calculations 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 D7500 is notably larger (16 percent) than the Sony A7 II. Moreover, the D7500 is markedly heavier (20 percent) than the A7 II. 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 will tend to go along with bigger and heavier lenses, although exceptions exist. You can find an overview of optics for the two cameras in the Sony FE Lens Catalog (A7 II) and the Nikon Lens Catalog (D7500). Mirrorless cameras, such as the Sony A7 II, have moreover the advantage that they have a relatively short flange to focal plane distance and can thus use many lenses from other systems via adapters.

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 D7500 was launched at a markedly lower price (by 35 percent) than the A7 II, 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.

Sensor comparison

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 A7 II features a full frame sensor and the Nikon D7500 an APS-C sensor. The sensor area in the D7500 is 57 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Sensor size

With 24MP, the A7 II offers a higher resolution than the D7500 (20.7MP), but the A7 II nevertheless has larger individual pixels (pixel pitch of 5.97μm versus 4.22μm for the D7500) due to its larger sensor. However, the D7500 is a somewhat more recent model (by 2 years and 4 months) than the A7 II, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.

Sensor resolution

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. Of the two cameras under review, the A7 II has a notably higher overall DXO score than the D7500 (overall score 4 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.099999999999998 bits higher color depth, 0.3 EV of lower dynamic range, and 1 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 D7500 provides a better video resolution than the A7 II. It can shoot movie footage at 4K/30p, while the Sony is limited to 1080/60p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the A7 II has an electronic viewfinder (2400k dots), while the D7500 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 table below summarizes some of the other core capabilities of the Sony A7 II and Nikon D7500 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.

Summary

So what conclusions can be drawn? Which of the two cameras – the Sony A7 II or the Nikon D7500 – has the upper hand? The listing below highlights the relative strengths of the two models.


logo checkmark

Reasons to prefer the Sony Alpha A7 II:

  • More detail: Offers more megapixels (24 vs 20.7MP) with a 8% higher linear resolution.
  • Better image quality: Scores markedly higher (4 points) in the DXO overall assessment.
  • Better low-light sensitivity: Requires less light for good images (1 stops ISO advantage).
  • More framing info: Has an electronic viewfinder that displays shooting data.
  • More detailed LCD: Has a higher resolution rear screen (1230k vs 922k dots).
  • More compact: Is smaller (127x96mm vs 136x104mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 121g or 17 percent) and hence easier to carry around.
  • More legacy lens friendly: Can take a broad range of non-native lenses via adapters.
  • Sharper images: Has hand-shake reducing image stabilization build-in.
  • More heavily discounted: Has been available for much longer (launched in November 2014).

Advantages of the Nikon D7500:

  • Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • Easier setting verification: Has a control panel on top to check shooting parameters.
  • Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • Faster burst: Shoots at higher frequency (8 vs 5 flaps/sec) to capture the decisive moment.
  • Longer lasting: Gets more shots (950 versus 350) out of a single battery charge.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • More affordable: Was introduced into a lower priced category (35 percent cheaper at launch).
  • More modern: Reflects 2 years and 4 months of technical progress since the A7 II launch.

If the count of individual advantages (bullet points above) is taken as a guide, the match-up finishes in a tie (10 points each). 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.

A7 II 10:10 D7500

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 A7 II or the D7500 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. The full reviews are available, respectively, at 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 were established in reference to similarly priced cameras that were available in the market at the time of the review. 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.
