Sony a7s Review: Mirrorless full format Sony Alpha 7S with 4K video introduced: Light sensitivity versus resolution

Sony has added its sister model Alpha 7S to the Alpha 7 and 7R mirrorless full-frame system cameras, the Alpha 7S, which does without high resolution in favour of high light sensitivity and 4K video with 1:1 sensor readout and manages with 12.2 megapixels. On the other hand, a maximum sensitivity of ISO 409.600 is achieved for both photo and video. With the ability to label 4K videos in QFHD (3,840 x 2,160 pixels) in 4:2:2 8 bit 24p or 25p only externally via HDMI recorder, it clearly addresses professional filmmakers.

With the Alpha 7S, Sony offers the A7 family a third model that resolves extremely reservedly with twelve megapixels. To achieve this, ISO sensitivity can be raised to dizzying heights. And that’s not all: the Alpha 7S comes with features that were previously reserved for professional video cameras.

Those who want to record videos on the inserted memory card have to be content with Full HD resolution (1,920 x 1,080) at 60 frames per second (60p). The data is saved in AVCHD format with 4:2:2 Subsampling. Frame rates of 30, 25 and 24 frames per second are also available with Full HD. If the video is captured in HD (1,280 x 720) by trimming, the Alpha 7S even achieves 120 frames per second, ideal for up to fivefold slow motion (then 24 frames per second). The clear advantage for video recording is the so-called “Full Pixel Read-out”, which does not combine pixels and therefore outputs every pixel 1:1 in the video. Although Panasonic doesn’t use a pixel summary for the Lumix DMC-GH4 either, due to the 16 megapixel resolution of the sensor, the GH4 has a not inconsiderable image trim (see further links), which is significantly smaller for the Sony Alpha 7S. Also the higher sensitivity is a clear advantage of the larger sensor with the larger pixels. In addition, a higher dynamic range should also be possible with the larger pixels. But the Panasonic GH4 keeps a trump card up its sleeve: It can record 4K videos to the SD memory card. Filmer will also be pleased that the A7S supports Time Code, for example, and can be equipped with an XLR adapter.

The standard sensitivity of the 35.8 x 23.9 millimeter CMOS sensor is ISO 100 to 102,400 for photos, ISO 200 to 102,400 for video, ISO 50 to 409,600 for photos and ISO 200 to 409,600 for video. Only the Nikon D4S offers such a high sensitivity. The high light sensitivity also benefits the contrast autofocus, which works at an ambient brightness of -4 LW. But there’s a little Harken here, too: The Alpha 7S uses the same autofocus technology as the Alpha 7R and therefore does not have the Alpha 7’s phased autofocus integrated on the sensor, which is slightly faster and offers advantages especially in subject tracking and autofocus tracking.

The Sony Alpha 7S has the same form factor as its sister models Alpha 7 and 7R. It is an extremely compact mirrorless full-frame system camera with a high-quality magnesium housing. The A7S has a 7.5 centimeter (1.23 million pixels) foldable up and down screen with four pixels (red, green, blue and white) forming a true color pixel. The electronic OLED viewfinder with a magnification of 0.71 offers a resolution of 2.36 million pixels. Sony also does without a built-in flash in the Alpha 7S, but the multi-interface shoe for connecting external flashes and other accessories is of course on board. In addition, the A7S has built-in WLAN and NFC, so it can be easily connected to a smartphone and remotely controlled from there, photos can be transferred directly. In addition, the camera functions can be extended via Play Memories apps, some of the apps are available free of charge, others cost a few euros.

Sony was also working on the full-frame E-Mount lens system; a lens specially adapted for video recording (Powerzoom) with a focal length of 28 to 135 millimetres and a continuous speed of F4.0 was developed.

Sony Alpha 7S is extremely compact for a full-frame camera and yet ergonomically handy.

Sony a7s Review

The Sony Alpha 7S has a magnesium-aluminium housing reinforced in the front so that even large and heavy video lenses do not deform the camera.

Sony a7s Review

Even though the Sony Alpha 7S is very compact, especially for a full-frame camera, it’s not really suitable for a jacket pocket due to the clumsy full-frame lenses, here the standard zoom with 28-70 mm that is weak in light.

The stand thread of the Sony Alpha 7S is made of metal and sits properly in the optical axis.

Ergonomics and workmanship

Sony makes it easy for itself. Instead of giving its youngest, mirrorless offspring an independent housing, the engineers simply pack the new technology into the dress of the Alpha 7R – and the Alpha 7S is ready. Well, Sony has already slightly reworked the Alpha 7S’s case; with an empty weight of 446 grams, it’s about 40 grams heavier than the Alpha 7R’s case. A stronger front section and a more stable bayonet are responsible for the weight gain – both are intended to ensure that a heavyweight (video) lens doesn’t dislodge the slim body of the Alpha 7S. By the way, this is also ensured by the material, the camera is largely made of an extremely tough but light magnesium-aluminium alloy.

Nothing new compared to the Alpha 7 and Alpha 7R, however, there is to report from the operation. Sony consistently continues the proven concept with the Alpha 7S. This includes an adjustment wheel only for the exposure correction as well as a quick menu that can be completely adapted to one’s own ideas. In addition, there is a range of knobs  that are also largely freely configurable. The basic configuration is quickly set via a mode dial. There are also two memory locations for individual camera configurations. Once you have assigned the many buttons and knobs as well as the slots in the quick menu to the functions you need most frequently, you rarely have to go to the main menu of the camera. If you do, you will quickly find your way around it. Sony has structured the menu neatly into tabs, there are no long lists in which you could get lost.

Although the Alpha 7S is almost dainty for a 35 mm camera, it lies well in the hand. This is due, among other things, to a wide, well-formed grip bead as well as a grippy thumb rest on the back – and of course the comparatively low weight of the camera. The front and thumbwheel as well as some other controls can be easily reached by the index finger or thumb, but Sony has arranged the adjustment wheel on the back very low. The Alpha 7S may be a little dainty for particularly large photographer hands – but then there’s the VG-C1EM vertical handle, which not only provides extra grip but also holds a second battery.

Just like its sisters Alpha 7 and Alpha 7R, the Alpha 7S also impresses with a large, clear viewfinder image that is usually forgotten to be produced electronically. In daylight, the electronic viewfinder reacts quickly and immediately, almost as directly as an optical viewfinder, but with the advantage of making incorrect camera settings visible. In the dark, the viewfinder image jolts perceptibly, but it doesn’t seem noisy or even grizzly. Alternatively, the Alpha 7S shows the viewfinder image on the rear display. It automatically switches from EVF to display as soon as the camera is removed from the eye. The monitor is pleasantly large with a diagonal of three inches and has a contemporary high resolution of almost one million pixels. It can be folded up and down, but not to the side.

Sony has hidden the USB and HDMI ports as well as the microphone and headphone jacks on the left side of the camera under neatly closing flaps. The memory card compartment is located on the right side of the camera, also under a robust flap. It accepts either an SD/SDHC/SDXC card or a MemoryStick. The lithium-ion battery is inserted on the underside, its range is somewhat limited with a maximum of 380 shots. After all, Sony has included a proper charging cradle with the Alpha 7S. Unlike a USB power supply unit, it can be used to charge a battery while a second one is already working in the camera. It’s also nice that the battery compartment remains accessible even when the quick-release plate is attached and that Sony has arranged the tripod thread neatly in the optical axis.

Slim and lissom: the Sony Alpha 7S.

Equipment

The appearance of the Alpha 7S is practically the same as that of the Alpha 7R and the Alpha 7, but the Alpha 7S has a lot more to offer – especially when it comes to video recording. First of all, however, she brings with her all the functions that her two older sisters have to offer. This includes, for example, an intelligent fully automatic system that relieves you of practically any adjustment work. Thus, you can also hand over the Alpha 7S to less experienced photographers with a clear conscience. In addition, there are the wizards that are now common at Sony, with whose help panorama shots or HDR photos are created almost by themselves. Also on board is a whole bouquet of effect options, without which today even a camera cannot do without the professional painting of an Alpha 7S.

Sony a7s Review

The lithium-ion battery of the Sony Alpha 7S is removed at the bottom, it is only sufficient for a good 380 shots.

What the Alpha 7S can do more, it reveals only after intensive exploration of the main menu. The ISO setting, for example, allows the sensitivity to be raised to a vertiginous ISO 409.600. Whether such a high ISO sensitivity still delivers useful results is a different matter (more on this in the section “Image quality”). In any case, the ISO automatic allows the choice of the very highest level, but can also be limited to a maximum and minimum value. It’s a bit of a shame that you can’t alternatively set a shutter speed that the camera shouldn’t undercut – some sports and action photographers might wish for such a function. On the other hand: The Alpha 7S is not an action camera anyway. Despite its rather low resolution and the associated manageable data rate, it only manages about 5 frames per second (fps) in continuous shooting mode – regardless of whether it is recorded in raw or JPEG format. At least the small amount of data of the Alpha 7S gives you a long breath: It takes 99 JPEG shots until it falls from a fast spurt into a continuous run with about 3 fps – but with raw shots the “sprint” is already over after 25 serial shots.

The Alpha 7S obviously inherited the mechanical lock from the 7R. Anyway, there’s a lot going on when you take a picture – the slim housing of the camera has only little damping mass to oppose the shutter. However, those who don’t like this will find an alternative to heavy metal in the Alpha 7S: As the first system camera from Sony, it offers a fully electronic shutter that releases absolutely vibration-free and silently. This not only makes very discreet photography possible, but also prevents any disturbing vibrations from occurring in the first place. However, the “silent shutter” blocks some functions, so that flash photography is not possible with it, the multiframe noise reduction or HDR automatic also do not work together with the fully electronic shutter.

Apart from the Panasonic GH4, there’s hardly another digital camera that’s as focused on professional video as the Sony Alpha 7S. Both record videos in maximum 4K resolution, the Alpha 7S however only on an external recording device. This may not bother the professional videographer, but for the demanding photographer this limitation takes away an important possibility: simply record a short clip and extract still images with a resolution of eight megapixels. Sony has designed the full-frame sensor of the Alpha 7S in such a way that every line on the image converter is completely read out during filming. This “full pixel red-out” without “line skipping” or “pixel binning” improves the image display and minimizes the “rolling shutter effect”. Video professionals will also be pleased that the Alpha 7S records timecodes, either in “Record Run” or “Free Run” mode.

The fact that Sony’s development of the Alpha 7S was primarily aimed at the demanding video filmmaker is demonstrated by a whole series of other functions that are unusual or even completely unknown in digital filming cameras. The Alpha 7S has seven memory locations for image profiles. These image profiles have little to do with the “image styles” known from digital photography. Rather, they allow very differentiated interventions in the gamma curve, detail reproduction, image saturation, etc.. Nine parameters can be set per image profile, from color mode to gamma to black level. The settings also apply to photo shots, so that stills recorded parallel to the film get an identical color and contrast impression. Sony has pre-configured the seven memory locations with different settings, which usually saves the videographer some adjustment time.

The Alpha 7S does not have an integrated flash light, but of course it has a flash shoe on board. If it is equipped with an external flash unit, the flash system leaves nothing to be desired. The Alpha 7S, for example, is designed for long-term synchronisation and can control unleashed system flash units wirelessly. The shortest possible sync time is 1/250 seconds, but Sony also provides an HSS mode with a much shorter flash sync time with the appropriate flash units. As usual with Sony, the Alpha 7S is also only very poorly equipped with editing options in playback mode. After all, the functional range of the camera can be extended in playback and recording mode with camera apps. Wifi also has the Alpha 7S on board, with which it can be remote-controlled via smartphone or tablet.

Lens

As usual with professional cameras, Sony doesn’t offer the Alpha 7S as a set with one lens. We mainly used it with the FE 28-70/3.5-5.6 OSS in the practical test, the camera also passed through the test laboratory with this lens. As already in the Alpha 7 test , the standard zoom proved to be a very balanced compromise between focal length range, light intensity and weight. In the practical test the quite new Telezoom FE 70-200/4 G OSS was added. Unlike the A-mount, where the image sensor is stabilized, these E-Mount lenses have an optical image stabilizer. It provides a stabilized viewfinder image as soon as the shutter release button is pressed halfway. It’s a pity that not all E-Mount lenses are stabilized, but with the fixed focal lengths available up to now you have to do without them.

The autofocus of the Alpha 7S differs only slightly from that of the Alpha 7R. It works exclusively by contrast measurement, additional phase comparison sensors on the image converter are reserved for the A7. Sony emphasizes that the FE mount lenses only have to move a small lens mass to focus and are therefore optimized for the basically somewhat slow contrast measurement. Equipped in this way, the Alpha 7S focuses and triggers within 0.3 seconds – a good value. If, however, it is supposed to track the focus in serial photos, the frame rate drops to a maximum of 2.5 fps – so the A7S is not a sports camera. The autofocus also works under light conditions where most other cameras are painting the sails: A light value of -4 EV is sufficient for the Alpha 7S to automatically adjust the distance. In practice, the autofocus on a pitch-dark night gets by with the light of a garden lantern in order to focus a portrait. However, he took a lot of time to do this, but on the other hand he did not use annoying focus pumps. If desired, an orange auxiliary light assists the AF in dark surroundings in order to focus more quickly at least on subjects in the vicinity.

Picture quality

With only twelve megapixels, no current 35mm camera offers such a low resolution as the Alpha 7S. On the other hand, this means that the individual sensor cells are correspondingly large and light-sensitive. This in turn means, at least in theory, that the image sensor of the Alpha 7S is very low-noise and delivers a very large dynamic range even at high ISO values. Sony, in any case, seems to think the Alpha 7S is capable of a lot in this respect and allows a maximum sensitivity of ISO 409.600.

It is to be expected that the output resolution of the Alpha 7S will not climb dizzying heights with only twelve megapixels of sensor resolution. With a maximum of around 42 line pairs per millimetre (lp/mm), however, it clearly lags behind the resolution values one is accustomed to from a full-frame camera today. It’s not the lens, the FE 28-70 mm 3.5-5.6 OSS, by the way – the A7 with 24 megapixels easily cracks the limit of 60 lp/mm. While the maximum resolution may be a bit low, the SEL-2870 on the Alpha 7S on the other hand pleases with very even values across the entire field of view. When stopped down on F8, the resolution loss to the image edges in the worst case is only 15 percent – a very good result! Sony has also corrected chromatic aberrations of the standard zoom to an excellent degree, color fringes on contrast edges play no role at all focal lengths. The FE 28-70 mm 3.5-5.6 OSS displays the measured values for distortion practically without distortion. Sony helps here by digitally correcting the distortions that are quite visible in raw shots directly in the camera. Fortunately, this doesn’t affect the sharpness of the image, even sharpness artifacts remain extremely low at all focal lengths and apertures.

The resolution of the Alpha 7S is therefore modest. Can it at least score groundbreaking high-ISO skills in return? At first, it doesn’t look that way: The signal-to-noise ratio is only really good up to ISO 800, it drops below the critical 35 dB mark at ISO 12,800. This at first glance disappointing result is certainly also due to a very restrained noise reduction. It permits grain with an unusually high size and dampens the annoying color noise just enough. This gentle noise suppression also has its pleasing sides: The texture sharpness remains very high up to ISO 25.600 and even at the maximum value of ISO 409.600 it does not drop critically far. When it comes to input dynamics, the Alpha 7S becomes a real high flyer. Not only can it process a contrast range of around eleven f-stops (EV), it can also withstand this high level up to ISO 12,800. But even if the ISO numbers are increased even further, the Alpha 7S drums up brightness differences surprisingly well: At ISO 51.200 it still processes contrasts of 10.0 EV, at ISO 102.400 it is still a good 9.4 EV. Alpha 7S behaves similarly well in terms of color fidelity. Although it could be a little more accurate overall, it also doesn’t impress with high ISO values and remains equally good up to ISO 51,200.

Sony has therefore less trimmed the Alpha 7S to low noise, but rather imbued it with outstanding input dynamics and ensured differentiated detail and color reproduction right up to high ISO spheres. While higher resolution full frame cameras up to about ISO 6,400 deliver usable results, the Alpha 7S can confidently be expected to deliver ISO 51,200 as well – after all, that’s a gain of three f-stops! At the latest from ISO 102.400 photographers will not be happy with what the Alpha 7S delivers. The situation is different with film shots, where grain is far less disturbing and the maximum resolution plays a subordinate role. Here the Alpha 7S shines with its still very good dynamic range and a still acceptable color differentiation.

Bottom line

The Alpha 7S is a very special camera with distinct strengths but also some weaknesses. Their high-ISO capabilities are outstanding – not necessarily in terms of low noise, but in terms of dynamic range and detail reproduction. However, these properties are purchased with only a moderate resolution. The video capabilities of the Alpha 7S are also undoubtedly strong. It is the first 35mm camera to record in UItra-HD (but only on an external device) and brings with it a number of professional video features that were previously unknown in digital cameras – and at a price significantly lower than that of Ultra-HD camcorders. With the Alpha 7S, photographers get one of the lightest and most compact 35 mm cameras currently available with an outstanding electronic viewfinder and good equipment. For a mirrorless system camera, the Alpha 7S offers a fixed autofocus, but the serial frame rate is lame – especially if the focus is to be adjusted. On the other hand, the autofocus still works in almost complete darkness, underscoring the camera’s low-light ambitions once again. If you are primarily interested in these, there is currently hardly any alternative to the Alpha 7S. As an all-round camera, the Alpha 7S with its low resolution and low frame rate is less suitable – there are better and cheaper alternatives such as the sister model Alpha 7 or the Nikon D610 or Canon EOS 6D.
