Going beyond this snapshot of core features and characteristics,
what are the differences
betwixt the Sony Alpha A7R II and the Sony Alpha 7S II? Which i should you buy? Read on to notice out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.

Body comparison

An analogy of the physical size and weight of the Sony A7R II and the Sony A7S II is provided in the side-by-side display beneath. The two cameras are presented according to their
relative size. Three consecutive views from the front, the summit, and the rear side are shown. All size dimensions are rounded to the nearest millimeter.

In this particular example, the Sony A7R II and the Sony A7S II take
exactly the aforementioned width and height, and, thus, have identically-sized bodies.
Yet, the A7S Ii is
slightly heavier (0 pct)
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 choppy weather weather or harsh environments.

The above size and weight comparisons are to some extent incomplete since they practice not consider the
interchangeable lenses that both of these cameras require. In this detail instance, both cameras feature the same lens mountain, and so that they can use the aforementioned lenses. You can compare the optics available in the Sony Atomic number 26 Lens Itemize. Mirrorless cameras, such as the two under consideration, accept the additional advantage of having a short flange to focal plane distance, which makes it possible to mount many lenses from other systems onto the photographic camera via adapters.

The battery packs of both cameras tin be
charged via USB, which tin can be very user-friendly when travelling.

The next table
lists the principal physical characteristics
of the ii cameras alongside a wider set up of alternatives. If you want to switch the focus of the display and review some other camera pair, you tin move beyond to the CAM-parator tool and choose from the wide option of possible camera comparisons there.

The price is, of course, an important factor in whatever photographic camera decision. The manufacturer’south suggested retail prices give an idea on the
placement of the camera in the maker’due south lineup
and the broader market. The A7S Ii was somewhat cheaper (by 6 percent) than the A7R II at launch, but both cameras fall into the same cost category. Usually, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. Afterward in the product bicycle and, in particular, when the replacement model is about to appear, further discounting and stock clearance sales oft push the photographic camera cost considerably down.

Sensor comparison

The size of the sensor inside a digital camera is 1 of the primal determinants of
paradigm quality. All other things equal, a large sensor will have larger individual pixel-units that offer better depression-light sensitivity, wider dynamic range, and richer colour-depth than smaller pixels in a sensor of the same technological generation. Farther, a large sensor camera will requite the lensman boosted creative options when using shallow depth-of-field to isolate a subject from its background. On the downside, larger sensors tend to be associated with larger, more expensive camera bodies and lenses.

Both cameras under consideration feature
a full frame sensor, merely their sensors differ slightly in size. The sensor area in the A7S II is 2 percent smaller. They nevertheless have the same format gene of 1.0. Both cameras accept a native aspect ratio (sensor width to sensor tiptop) of 3:2.

With 42.2MP, the A7R II offers a
higher resolution
than the A7S II (12MP), but the A7R 2 has smaller individual pixels (pixel pitch of 4.52μm versus 8.40μm for the A7S II). Moreover, the A7S Ii is a somewhat more recent model (past three months) than the A7R II, and its sensor might have benefitted from technological advances during this time that farther enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the A7R II has no anti-alias filter installed, so that information technology tin capture all the item its sensor resolves.

The resolution advantage of the Sony A7R 2 implies greater flexibility for cropping images or the possibility to print larger pictures. The
maximum print size
of the A7R II for adept quality output (200 dots per inch) amounts to 39.8 10 26.5 inches or 101 x 67.iv cm, for very good quality (250 dpi) 31.viii x 21.2 inches or lxxx.8 x 53.nine cm, and for excellent quality (300 dpi) 26.v x 17.7 inches or 67.3 x 44.nine cm. The corresponding values for the Sony A7S Ii are 21.two x xiv.two inches or 53.8 x 36 cm for expert quality, 17 x 11.3 inches or 43.1 x 28.viii cm for very good quality, and xiv.1 x 9.four inches or 35.nine x 24 cm for excellent quality prints.

The A7R II has
on-sensor phase discover pixels, which results in fast and reliable autofocus conquering fifty-fifty during live view functioning.

The Sony Alpha A7R Two has a native
sensitivity range
from ISO 100 to ISO 25600, which can be extended to ISO 50-102400. The respective ISO settings for the Sony Alpha 7S II are ISO 100 to ISO 102400, with the possibility to increase the ISO range to 50-409600.

In terms of underlying engineering, the A7R II is build effectually a BSI-CMOS sensor, while the A7S II uses a CMOS imager. Both cameras apply a
Bayer filter
for capturing RGB colors on a square grid of photosensors. This arrangement is establish in most digital cameras.

Since 2007, DXO Mark has published
sensor operation measurements
that take been derived using a consistent methodology. This service is based on lab testing and assigns an overall score to each camera sensor, too as ratings for dynamic range (“DXO Mural”), color depth (“DXO Portrait”), and low-low-cal sensitivity (“DXO Sports”). Of the 2 cameras under review, the A7R Two provides
substantially higher paradigm quality
than the A7S II, with an overall score that is 13 points higher. This advantage is based on 2.iv bits college color depth, 0.6 EV in additional dynamic range, and 0.two stops in additional low calorie-free sensitivity. The next tabular array reports on the concrete sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras cannot just take notwithstanding pictures, but also
tape videos. Both cameras nether consideration are equipped with sensors that accept a sufficiently loftier read-out speed for moving images, and both provide the aforementioned movie specifications (4K/30p).

Feature comparison

Autonomously from body and sensor, cameras can and do differ across a range of features. The A7R II and the A7S 2 are like in the sense that both characteristic an
electronic viewfinder, which is helpful when framing images in bright sunlight. Moreover, their viewfinders offer an identical resolution of 2400k dots. The table below summarizes some of the other cadre capabilities of the Sony A7R Ii and Sony A7S II in connexion with corresponding data for a sample of similar cameras.

The reported shutter speed data refers to the utilise of the mechanical shutter. Even so, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical ane. In fact, both cameras under consideration characteristic an
electronic shutter, which makes completely silent shooting possible. Still, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting nether bogus calorie-free sources (take chances of flickering).

Concerning the storage of imaging data, both the A7R II and the A7S II write their files to
SDXC or Retentivity Stick PRO Duo cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed information transfer of up to 104 MB/s.

Connectivity comparison

For some imaging applications, the extent to which a camera tin communicate with its environment can be an important attribute in the camera determination procedure. The table beneath provides an overview of the connectivity of the Sony Alpha A7R Two and Sony Alpha 7S II and, in detail, the interfaces the cameras (and selected comparators) provide for
accessory command and information transfer.

Both the A7R Ii and the A7S Two
have been discontinued, but can regularly be plant used on ebay. The A7R II was replaced by the Sony A7R Three, while the A7S II was followed by the Sony A7S III. Further information on the features and operation of the A7R Ii and A7S 2 tin exist found, respectively, in the Sony A7R Two Manual (costless pdf) or the online Sony A7S II Transmission.

Review summary

So what conclusions can be drawn? Which of the 2 cameras – the Sony A7R 2 or the Sony A7S Two – has the upper hand? Is one conspicuously better than the other? A synthesis of the
relative potent points
of each of the models is listed beneath.

Reasons to prefer the Sony Blastoff A7R Ii:

• More detail:
  Offers more megapixels (42.2 vs 12MP) with a 87% college linear resolution.
• Maximized detail:
  Lacks an anti-alias filter to exploit the sensor’s total resolution potential.
• Better prototype quality:
  Scores essentially higher (13 points) in the DXO overall assessment.
• Richer colors:
  Generates images with noticeably amend colors (2.4 bits more color depth).
• More than dynamic range:
  Captures a larger spectrum of light and dark details (0.half dozen EV of extra DR).
• Better live-view autofocus:
  Features on-sensor stage-detection for more confident autofocus.
• More heavily discounted:
  Has been on the market for longer (launched in June 2015).

Advantages of the Sony Alpha 7S II:

• Better moiré control:
  Has an anti-allonym filter to avert artificial patterns to appear in images.
• Longer lasting:
  Gets more shots (370 versus 290) out of a single bombardment charge.
• More modern:
  Was introduced somewhat (3 months) more recently.

If the count of relative strengths (bullet points above) is taken equally a measure out, the A7R Two is the clear winner of the match-up (7 : iii points). Withal, the
pertinence of the various camera strengths will differ
across photographers, so that you lot might want to counterbalance individual camera traits co-ordinate to their importance for your ain imaging needs before making a photographic camera determination. A professional person wildlife photographer will view the differences between cameras in a manner that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports shooter. Hence, the decision which camera is all-time and worth buying is frequently a very personal one.

In whatsoever case, while the comparison of technical specifications tin provide a useful overview of the capabilities of dissimilar cameras, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when
actually working
with the A7R II or the A7S 2. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Skilful reviews

This is where
reviews by experts
come in. The tabular array beneath provides a synthesis of the camera assessments of some of the best known photo-gear review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). Every bit tin be seen, the professional person reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier indicate that a camera decision is oftentimes a very personal choice.

The higher up review scores should be
interpreted with care, though. The ratings are only valid when referring to cameras in the same category and of the aforementioned historic period. Thus, a score needs to be put into the context of the launch engagement and the launch toll of the camera, and rating-comparisons among cameras that span long fourth dimension periods or concern very differently equipped models make little sense. Also, kindly annotation that some of the listed sites have over time developped their review approaches and their reporting mode.
