Sony A7R II versus Nikon D610

The Sony Alpha A7R II and the Nikon D610 are two enthusiast cameras that were revealed to the public, respectively, in June 2015 and October 2013. The A7R II is a mirrorless interchangeable lens camera, while the D610 is a DSLR. Both cameras are equipped with a full frame sensor. The Sony has a resolution of 42.2 megapixel, whereas the Nikon provides 24.2 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: Sony A7R II vs Nikon D610

The side-by-side display below illustrates the physical size and weight of the Sony A7R II and the Nikon D610. 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 A7R II – 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 Nikon D610 is notably larger (31 percent) than the Sony A7R II. Moreover, the D610 is substantially heavier (36 percent) than the A7R 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. Both cameras have similarly sized sensors, but DSLRs have a larger flange-to-focal plane distance than mirrorless cameras, which imposes contraints on the optical engineering process and generally leads to bigger and heavier lenses. You can find an overview of optics for the two cameras in the Sony FE Lens Catalog (A7R II) and the Nikon Lens Catalog (D610). Mirrorless cameras, such as the Sony A7R 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.

Concerning battery life, the A7R II gets 290 shots out of its NP-FW50 battery, while the D610 can take 900 images on a single charge of its EN-EL15 power pack.

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 camera comparisons there.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The D610 was launched at a markedly lower price (by 38 percent) than the A7R 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: Sony A7R II vs Nikon D610

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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Both cameras under consideration feature a full frame sensor and have a format factor (sometimes also referred to as "crop factor") of 1.0. Within the spectrum of camera sensors, this places the review cameras among the large-sensor cameras that aim for top notch image quality. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Sony A7R II and Nikon D610 sensor measures

While the two cameras under review share the same sensor size, the A7R II offers a higher resolution of 42.2 megapixel, compared with 24.2 MP of the D610. This megapixel advantage translates into a 32 percent gain in linear resolution. On the other hand, these sensor specs imply that the A7R II has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 4.52μm versus 5.97μm for the D610). In this context, it should be noted, however, that the A7R II is a somewhat more recent model (by 1 year and 8 months) than the D610, and its sensor might have benefitted from technological advances during this time that at least partly compensate for the smaller pixel size. Coming back to sensor resolution, it should be mentioned that the A7R II has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

A7R II versus D610 MP

For many cameras, data on sensor performance has been reported by DXO Mark. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). Of the two cameras under review, the A7R II has a notably higher overall DXO score than the D610 (overall score 4 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.9 bits higher color depth, 0.5 EV of lower dynamic range, and 0.2 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 are not only capable of taking still images, but can also record movies. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the A7R II provides a higher video resolution than the D610. It can shoot video footage at 4K/30p, while the Nikon is limited to 1080/30p.

 

Feature comparison: Sony A7R II vs Nikon D610

Apart from body and sensor, cameras can and do differ across a range of features. For example, the A7R II has an electronic viewfinder (2400k dots), while the D610 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 A7R II and Nikon D610 along with similar information for a selection of comparators.

The D610 is a current model that online retailers, such as amazon, will have in stock. In contrast, the A7R II has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the A7R II was succeeded by the Sony Alpha A7R III.

Review summary: Sony A7R II vs Nikon D610

So what is the bottom line? Is the Sony A7R II better than the Nikon D610 or vice versa? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Arguments in favor of the Sony Alpha A7R II:

  • More detail: Offers more megapixels (42.2 vs 24.2MP) with a 32% higher linear resolution.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Better image quality: Scores markedly higher (4 points) in the DXO overall assessment.
  • Better video: Provides higher definition movie capture (4K/30p vs 1080/30p).
  • More framing info: Has an electronic viewfinder that displays shooting data.
  • More detailed LCD: Has a higher resolution rear screen (1229k vs 921k dots).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • More compact: Is smaller (127x96mm vs 141x113mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 225g or 26 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 modern: Is somewhat more recent (announced 1 year and 8 months after the D610).

ilogo

Advantages of the Nikon D610:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • 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.
  • Faster burst: Shoots at higher frequency (6 vs 5 flaps/sec) to capture the decisive moment.
  • Longer lasting: Gets more shots (900 versus 290) 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 (38 percent cheaper at launch).
  • More heavily discounted: Has been on the market for longer (launched in October 2013).

If the number of relative strengths (bullet points above) is taken as a guide, the A7R II is the clear winner of the match-up (13 : 9 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision on a new camera.

A7R II 13:09 D610

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 A7R II or the D610. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased. This is why hands-on reviews by experts are important.

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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
