Going beyond this snapshot of core features and characteristics, what are the differences between the Sony Alpha A7S and the Sony Alpha A850? Which one should you buy? Read on to find 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: Sony A7S vs A850

The physical size and weight of the Sony A7S and the Sony A850 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth measures are rounded to the nearest millimeter.

Compare A7S versus A850 top
Comparison A7S or A850 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A850 is considerably larger (53 percent) than the Sony A7S. Moreover, the A850 is substantially heavier (83 percent) than the A7S. 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. Hence, you might want to study and compare the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.

Concerning battery life, the A7S gets 380 shots out of its NP-FW50 battery, while the A850 can take 880 images on a single charge of its NP-FM500H power pack. The power pack in the A7S can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The A850 was launched at a somewhat lower price (by 20 percent) than the A7S, which makes it more attractive for photographers on a tight budget. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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 A7S vs A850

The size of the sensor inside a digital camera is one of the key determinants of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units 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 more expensive and lead to bigger and heavier cameras and lenses.

Both cameras under consideration feature a full frame sensor, but their sensors differ slightly in size. The sensor area in the A850 is 1 percent bigger. They nevertheless have the same format factor of 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Sony A7S and Sony A850 sensor measures

With 24.4MP, the A850 offers a higher resolution than the A7S (12MP), but the A850 has smaller individual pixels (pixel pitch of 5.94μm versus 8.45μm for the A7S). Yet, the A7S is a much more recent model (by 4 years and 7 months) than the A850, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.

The resolution advantage of the Sony A850 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A850 for good quality output (200 dots per inch) amounts to 30.2 x 20.2 inch or 76.8 x 51.2 cm, for very good quality (250 dpi) 24.2 x 16.1 inch or 61.4 x 41 cm, and for excellent quality (300 dpi) 20.2 x 13.4 inch or 51.2 x 34.1 cm. The corresponding values for the Sony A7S are 21.2 x 14.2 inch or 53.8 x 36 cm for good quality, 17 x 11.3 inch or 43.1 x 28.8 cm for very good quality, and 14.1 x 9.4 inch or 35.9 x 24 cm for excellent quality prints.

The Sony Alpha A7S has a native sensitivity range from ISO 100 to ISO 102400, which can be extended to ISO 50-409600. The corresponding ISO settings for the Sony Alpha A850 are ISO 200 to ISO 3200, with the possibility to increase the ISO range to 100-6400.

A7S versus A850 MP

For many cameras, data on sensor performance has been reported by DXO Mark. 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 A7S has a notably higher overall DXO score than the A850 (overall score 8 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.099999999999998 bits higher color depth, 1 EV in additional dynamic range, and 1.4 stops in additional low light sensitivity.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The A7S indeed provides movie recording capabilities, while the A850 does not. The highest resolution format that the A7S can use is 1080/60p.

 

Feature comparison: Sony A7S vs A850

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the A7S has an electronic viewfinder (2400k dots), while the A850 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 viewfinder in the A7S offers a wider field of view (100%) than the one in the A850 (98%), so that a larger proportion of the captured image is visible in the finder. On the other hand, the viewfinder of the A850 has a higher magnification (0.74x vs 0.71x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Sony A7S and Sony A850 in connection with corresponding information for a sample of similar cameras.

One feature that differentiates the A850 and the A7S is in-body image stabilization (IBIS). The A850 reduces the risk of handshake-induced blur with all attached lenses, while the A7S has to rely on optical image stabilization in OIS-equipped lenses to achieve the same effect.

The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the A7S is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).

The A7S writes its imaging data to SDXC or Memory Stick PRO Duo cards, while the A850 uses Compact Flash or Memory Stick PRO Duo cards. The A850 features dual card slots, which can be very useful in case a memory card fails. In contrast, the A7S only has one slot.

 

Connectivity comparison: Sony A7S vs A850

For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Sony Alpha A7S and Sony Alpha A850 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the A7S offers wifi support, while the A850 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Studio photographers will appreciate that the Sony A850 (unlike the A7S) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the A7S and the A850 have been discontinued, but can regularly be found used on eBay. The A7S was replaced by the Sony A7S II, while the A850 does not have a direct successor. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Sony website.


Review summary: Sony A7S vs A850

So what is the bottom line? Which of the two cameras – the Sony A7S or the Sony A850 – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.


Arguments in favor of the Sony Alpha A7S:

  • Better image quality: Scores markedly higher (8 points) in the DXO overall assessment.
  • More dynamic range: Captures a larger spectrum of light and dark details (1 EV of extra DR).
  • Better low-light sensitivity: Requires less light for good images (1.4 stops ISO advantage).
  • Broader imaging potential: Can record not only still images but also 1080/60p movies.
  • More framing info: Has an electronic viewfinder that displays shooting data.
  • More complete view: Has a viewfinder with a larger field of view (100% vs 98%).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Faster burst: Shoots at higher frequency (5 vs 3 flaps/sec) to capture the decisive moment.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • More compact: Is smaller (127x94mm vs 156x117mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 406g or 45 percent) and hence easier to carry around.
  • Easier travel charging: Can be conveniently charged via its USB port.
  • More legacy lens friendly: Can take a broad range of non-native lenses via adapters.
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • More modern: Reflects 4 years and 7 months of technical progress since the A850 launch.


Advantages of the Sony Alpha A850:

  • More detail: Has more megapixels (24.4 vs 12MP), which boosts linear resolution by 43%.
  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.74x vs 0.71x).
  • Easier setting verification: Features a control panel on top to check shooting parameters.
  • Longer lasting: Gets more shots (880 versus 380) out of a single battery charge.
  • Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
  • More affordable: Was released into a lower priced segment (20 percent cheaper at launch).
  • More heavily discounted: Has been around for much longer (launched in August 2009).

If the count of relative strengths (bullet points above) is taken as a measure, the A7S is the clear winner of the match-up (15 : 10 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. A professional wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

How about other alternatives? Do the specifications of the Sony A7S and the Sony A850 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best DSLR Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the A7S and the A850 in practical situations. 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.

Expert reviews: Sony A7S vs A850

This is why expert reviews are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier point that a camera decision is often a very personal choice.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (-) not available.

The above review scores should be interpreted with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
