Sony α7S II Full-frame Mirrorless Interchangeable-Lens Camera
The α7S II has evolved in both Stills and Movies adding internal 4K video recording (1), uncompressed 14-bit RAW, 5-axis image stabilization, High-speed AF while maintaining its legendary low-light capability.
12.2 MP full-frame sensor for low light & wide dynamic range
The innovative α7S II features a 12.2 effective megapixel full-frame Exmor CMOS sensor paired with a powerful BIONZ X image processor, allowing it to shoot at a sensitivity range of ISO 50 – 4096004(2) with unprecedented dynamic range. The extra-large pixels on the α7S II collects dramatically more light than traditional cameras to produce beautifully detailed low-noise images in even the most challenging lighting situations.
World’s first5 Full-frame 4K movie recording1
The α7S II is the world’s first5 camera to offer internal 4K movie recording1 in the full-frame format with full pixel readout and no line skipping or pixel binning - resulting in images that exhibit higher resolution and less moiré and jaggies than typical 4K movies. It also provides you the option of shooting 4k in the super 35mm format and the ability to capture uncompressed 4:2:2 Full HD or 4K QFHD output via HDMI to optional 3rd party external recorders6. Enjoy the improved autofocus with 169 AF points and let every lens benefit from the 5-ais SteadyShot INSIDE image stabilization.
Fast precise focusing in light as low as EV -4
The α7S II has been upgraded from the α7S and now offers 169 AF points for fast, precise focusing with greater accuracy compared to the original α7S. The low signal-to-noise ratio produced by the image sensor of the α7S II enables the Fast Intelligent AF to detect contrast more easily and react speedily even in low-light situations (as low as EV-4), when it’s even tough to check focus with the naked eye. The AF performance on the α7S II is also twice as fast as the α7S during video shooting.
5-axis in-body image stabilization benefits every lens
The 5-axis SteadyShot inside image stabilization system is fine-tuned for 4k video capture. It accurately compensates for blur caused by camera shake from five different directions—vertical, horizontal, pitch, yaw and roll—as opposed to only two in previous systems. The 5-axis image stabilizing system excels during video recording and even compensates for blur caused by the user walking or running. It’s a true marvel of engineering. You can even monitor the stabilizing effects of camera shake compensation in the viewfinder or LCD screen while shooting still images by pressing the shutter button halfway or magnifying the image, and while shooting movies by entering movie mode.
User selectable compressed or uncompressed 14-bit RAW still
The α7S II offers the option of user selectable compressed or uncompressed 14-bit RAW still image. Uncompressed 14-bit RAW maximizes the benefit of the image sensor's wide dynamic range, delivering the smoothest, richest color quality and tonal gradation while compressed RAW offers more convenient file sizes.
120P Full HD 1920x1080 high-frame rate video3
For the first time ever in the Sony α7 series camera, the α7S II can support high frame rate 120fps shooting in full-HD resolution (1920x1080) using the entire full frame sensor. Video can be saved in Full HD resolution as 1920x1080/120p at 100Mbps3 or as a convenient slow motion footage as 5x 24p at 12mbps or 4x 30p at 16mbps.
Supports Picture Profiles, S-Gamut3.Cine/S-Log3
The α7S II boasts numerous features, common to Sony’s range of professional video cameras that enhance a cinematographer’s ability to capture breathtaking video while benefiting their workflow. Video functionality has been enhanced with new picture profile settings; S-Gamut3, Cine/S-Log3 and S-Gamut3/S-Log3, simplifying color correction and delivering wide dynamic range (up to 1300%). The α7S II even offers impressive 14-stop latitude in the S-Log3 gamma setting, while also supporting other popular profiles for cinematographers including S-Gamut/S-Log2 that can adjust settings like gamma, black, level and color adjustment, and can be saved for use in a multi-camera shoot. Other enhancements include the addition of Gamma Display Assist, a new function that allows users to pre-visualize the post-graded video when recording S-Log movies, and the improvement of the Zebra function for even greater control.
2.4-million dot XGA OLED Tru-Finder w/ ZEISS T coating
The XGA OLED Tru-Finder in the α7S II has been upgraded with the world’s highest viewfinder magnification (7) of 0.78x (roughly 38.5 degrees in diagonal field of view) and shows clear images across the entire display area. The use of ZEISS T Coating ensures sharp reduction of reflections on the viewfinder. Unlike an optical viewfinder, the OLED Tru-Finder can be used to instantly show how exposure compensation, white balance and other selected settings are affecting the displayed image.
Durable reduced-vibration shutter
The α7S II ‘s shutter includes a new braking mechanism which cuts mechanical front/rear curtain vibration by about 50% (2). Additionally, you can use the electronic front curtain shutter mode for even less vibration. This not only minimizes camera shake that can blur details and also reduces noise. Silent shutter mode eliminates shutter activation entirely for completely silent shooting. The new shutter mechanism on the α7S II is extremely durable having being tested to 500,000 cycles8.
Simple connectivity to smartphones via Wi-Fi/NFC (9).
Thanks to built-in Wi-Fi, you can easily connect to a compatible iOS or Android smartphone or tablet with the free PlayMemories Mobile App. From there you can control your camera, preview and frame using your mobile device and trigger the camera shutter or movie button. Then instantly transfer a photo or MP4 movie to your device. NFC (Near Field Communication) provides 'one-touch connection' convenience to Android smartphones and tablets with NFC. Simply touch devices to connect. Setting up your mobile device is as simple as downloading a free PlayMemories Mobile app.
Personalize your camera with PlayMemories Camera Apps (4).
Add new features to your α7S II with PlayMemories Camera Apps4. Find apps to fit your shooting style - with everything from time lapse, motion shot and more. Use apps that shoot, share and save photos to your smartphone using Wi-Fi, making it easy to post photos directly to your favorite social media site or backup images to the cloud without connecting to a computer.
Wider lens compatibility
Directly compatible with the growing family of E-mount lenses, the α7S II can also be used with Sony’s A-mount and others lens systems with optional adapters10. Sony’s complete α lens system includes several premium offerings from Carl Zeiss and G Series Lenses. Sony’s E-mount lens system is particularly well-suited for video shooting, with a variety of models containing 'movie-friendly' features like smooth focusing, powered zoom control, and silent iris/aperture control. 5-axis image stabilization lets you enjoy unparalleled handheld shooting freedom with more of your favorite mountable lenses.

The Good, The Bad and The Ugly
As all the camera reviews state, the low light performance of the a7S is incredible. It's 2+ stops better than my Canon 5D3. Files up to ISO 25,800 are very usable with comparatively minimal noise reduction. Sony has managed to make a camera with all the advantages of a full frame sensor in a small, lightweight size. The camera's sensor, processor and software create beautiful image files. At first I had reservations about the electronic viewfinder but after using the camera for a few days, I found it to be bright and accurate which was great because I prefer to hold the camera to my eye rather than use the LCD back. The silent shooting mode is very nice, especially for use on movie sets although, under many indoor lighting situations, severe banding occurs. The whole a7 series is designed to use lens adapters (I use one from Fotodiox) so photographers can enjoy a wide variety of current and vintage non-Sony lenses. My colleagues use Leica, Contax, Zeiss and other premium manual focus lenses. I've chosen to use old Nikkor lenses I had on hand from my 35mm film days and Sony's focus peaking helps to show what is and what isn't in focus.
For several months, I thought that my little a7S was close to being the ultimate camera and was seriously considering getting an a7R...that is, until I needed to have my camera serviced.
On June 21, 2015, it was 85 degrees outdoors with high humidity...a fairly typical summer day in the Midwest. I was photographing a Converse One Star World Tour Demo event at a local skatepark. There wasn't a breeze and it felt much hotter on the concrete. Like everyone else, I was sweating and happened to sweat a little on my a7S. After a while, the electronic viewfinder stopped working properly. The image was dim with static and occasionally, a pink line would cycle through. Because I was using manual focus lenses and it was bright out, I needed to see through the viewfinder so when it quit working properly, my day of shooting was over.
When I got home, I put the camera in a ziplock bag with silica gel pack. The camera worked fine for a while but when introduced into humid environments like abandoned buildings while urban exploring or just an average summer day, the camera would act up again. Eventually, the viewfinder worked consistently but the issue moved to the shutter speed. It would get stuck on a narrow range of speeds...usually it was somewhere between 1/800 - 1/1600. Because I came to rely on this camera, I found a workaround by adjusting the ISO up or down depending on the level of light.
In October, I shot a corporate national conference and all the meetings and events were indoors. With the shutter stuck at a fast speed, a high ISO was required and that meant more noise in the images. It was time to send the body in for repairs.
"We have been in business for 58 years and it is our goal to make your service experience a positive one." - From Precision Camera's Oct. 28 confirmation email
I found out the hard way that there's a huge difference between Canon's factory service department and Sony's contracted service company, Precision Camera.
Sony's website indicates that Precision Camera was Sony's official repair company. I thought it was weird that Sony didn't have their own service department like Canon and Nikon. I filled out the required online form explaining the issues with my camera, gave them my credit card number which authorized them to charge $384.45 for services and expected to get my camera back repaired, cleaned and ready to use, just like my experience had been with Canon.
Precision received my camera on October 28. Twelve days later, I see that my camera has been flagged so I called to find out what was going on. After two conversations with low level people who answer the phones, I was finally able to speak with Mia, a manager on Nov. 11.
She said that the service department saw "internal corrosion" and that they were not going to fix the camera. She did not know how much "internal corrosion" there was, nor did she know where it was. She asked if the camera was ever in the rain or had water splashed on it. I was up front when I told her about shooting with the camera up to my eye on a hot humid day and I sweated on it a little. She continued to refuse to authorize repairs and said my only recourse was to talk to Sony.
While Precision's customer service and repair was lacking, the speed at which they returned my camera was impressive. It was at my front door on Nov. 12.
- Nov. 18 11:54 CST - I called Sony's customer service number, 888-222-7669, and spoke with Larry. After I explained my situation, he said he'd "escalate the customer service request" and "someone should call in 24 - 48 hours".
- Nov. 20 4:11 CST - After not hearing back within Sony's timeframe, I called and spoke with Mark. After explaining my situation which he said he could see on his screen, he set said he'd set my request to "high priority" but that I "should have already heard back". I received a call from an odd number...102-796-3360. I answered but there was no one there. A minute later, it happened again with no one on the other end. I looked up area code 102 and it wasn't listed as coming from the US. Soon after, I received an email from Marge whose title was "Sony National Customer Relations" saying that she'd tried to contact me and assigned my case a number. I quickly returned her email but to date, haven't received a reply.
- Nov. 20 5:45 CST - I called the Sony service number again, hoping to speak with Marge and got Larry who I spoke with two days earlier. What are the chances I'd call a huge international company like Sony and the same person would answer the phone? He said that Sony would not repair the camera. After I insisted on talking to a manager, he put in that request and said one would call me within 24 hours.
- Nov. 23 3:01 CST - After not hearing back within Sony's timeframe again, I called the service number and talked to Alex. He said that on Nov. 22, Sony had emailed Precision to request a diagnosis of the service needed to fix the camera and quote on the repair. He read the email which said that Precision had replied to their request and determined it "would cost too much to repair", even though there was not an actual amount quoted. I also asked about the 102 area code. He said that "customer relations uses internet phone lines" so that may be why the area code isn't listed as being from the US.
- Nov. 23 3:08 CST - I received a call from Molly soon after my call with Alex was completed. She identified herself as being with "customer relations". If my previous calls weren't with people in the customer relations department, who were those people? She repeated what Alex had told me, that Precision determined it was too expensive to fix my camera. The strange thing is that to my knowledge, Precision never gave me a quote to repair the camera. Further, Precision said they wouldn't fix the camera, not that they couldn't...big difference. Molly apologized multiple times and said that Sony would not repair my camera because it would "cost too much" and that "it was out of warranty". Since when does "out of warranty" mean a company should stop servicing their products leaving their customers stuck with expensive equipment that doesn't work? I've sent two generations old camera bodies and lenses back to Canon for their factory service with no issues. My friends who use Nikon have had the same experience with Nikon factory service. Sony and their contracted service provider, Precision's refusal to service equipment out of warranty falls well short of general industry wide customer service practices. I requested that Molly transfer me to her manager but she said that there was no one higher in the company I could talk to. Was she the CEO or a board member? Doubtful because she seemed to be reading off a script...when the customer says X, reply Y and try to move on to the next call. This scheme is common with companies who contract their customer service to other companies (usually in other countries), hoping their customer complaints go away instead of providing customer service.
I had run into a solid customer service brick wall and she needed to get her call quota in for the day.
The call lasted 17 minutes 51 seconds before Molly shockingly hung up on me.
(Hopefully Not) The End
Even though the a7S is advertised as professional grade, whatever weather resistance the camera has, it isn't adequate. Over the years, I've used my Canon 1D3, 1D4, 5D, 5D2 and 5D3 bodies in some of the most extreme conditions. From ambient temperatures of over 110 degrees to downpours to blizzards to being exposed to severe helicopter vibrations in a warzone, my Canons have held up very well. When there is an issue, Canon has stood behind their products with good customer service. In contrast with my first experience with Sony, the company falls well short.
Sony has created a potentially great line of cameras that could change the entire industry. However, Sony/Precision's customer service is so completely inadequate, it's their Achilles heel and the fatal flaw in the a7 line of cameras. Sony has put itself at the mercy of Precision, a contracted service company who is clearly more concerned with lowering service costs than providing good customer service. Does this mean that Sony has surrendered customer retention in favor of just trying to get a constant stream of new customers?
Does the a7S II have better weather resistance? Sony's website doesn't say so.
I believe that Sony is capable of doing much better and I hope they prove me right.
But in the mean time, the a7S is a great camera while it works but an expensive paperweight because of poor to non-existent service from Sony/Precision when it doesn't.
UPDATE - January 2, 2016
After sharing my Sony/Precision service experience in multiple places online on November 30, Cyber Monday, I received a phone call from Johnny Pham, a Sony service employee. While I suspected that the people working at the Sony service switchboard were contracted workers, it was good to finally speak to someone who actually worked at Sony.
Johnny apologized for the issues I was having with my camera and getting it repaired through Precision Camera. We had a great conversation about industry standard service as set by Canon and Nikon. We talked about how if Sony wanted to compete in the professional photography market with their Alpha series cameras, they would need to provide great service to their professional customers who use their cameras in conditions other than birthday parties, Bar Mitzvahs and family photos. He indicated that Sony was making an effort to do that. He asked that if Sony provided good service, if I would take down my poor reviews and when I questioned that, he quickly backtracked and asked if I would update them. I agreed to do that.
He emailed a shipping label to send the camera back in on December 1. Precision took a second look at it and Sony/Precision AGAIN said that they wouldn't repair it.
After waiting for my camera to be sent back, I called Johnny and asked when I was going to get my camera back. He said he didn't realize that Precision was still hanging on to it and he will have it shipped to my home. He offered to sell me another A7S for 30% off retail. He quickly jumped to 40% off and now currently, the offer is at 50% off retail price.
I just wanted my camera repaired, not negotiate back and forth like I was at a used car lot.
On December 14, I finally received my A7S. When I opened the package and tested the camera, I was shocked and extremely disappointed when it flashed: Camera Error. Turn power off then on. It flashed the message when the camera was both on and off. The only way to stop it was to take the batteries out. There were no other functions working.
After all the phone calls, emails and twice sending my A7S to Precision Camera, my camera went from partially working to completely bricked and unusable while in Precision's possession!
I contacted Johnny immediately and he sent another shipping label later that day. I sent the camera in for a third time and shockingly, Sony refused to repair it AGAIN!
Sony's position is that electronic equipment will fail sooner or later.
So after Precision "looked" at my A7S two times, it went from partially working to completely bricked...after looking at it a third time, Sony determined that this is a completely normal situation and was not going to repair or replace it.
THIS IS COMPLETELY UNACCEPTABLE.
It seems like Sony is stuck in a mindset where they expect the customer to replace a broken camera rather than repair it. My professional peers and colleagues don't do that. As expensive as pro equipment is, I doubt that's the prevailing practice anywhere. Further, the weather sealing in the A7S is weak or non-existent. This design flaw is the basis of my camera problems. Sony and Precision, they refuse to acknowledge that and Sony doesn't advertise the new models of Alphas with better weather sealing so I can only assume the same issue exists.
Based on my experience, professional and semi-professional photographers should stay away from Sony cameras because their service is awful. Amateurs, if you absolutely have to buy a Sony camera, get a cheap model because it will be less expensive to replace. Better yet, get a Canon or Nikon because unlike Sony, they stand behind their products.
Sony, I know you read these reviews. Do the right thing and replace my camera which completely quit working while in the possession of Precision Camera, your contracted service company.
Bottom line is that Sony is not honoring the warranty due to the corrosion. So, after only owning the camera for a few months, I now have a brick on my hands. Because the only thing I did was use it in normal conditions, I'm totally bummed and disappointed in Sony.
I'm guessing that at least my camera had some problem with weatherproofing, but after a little googling, I found others with my same problem. So, I would be careful with this camera as it is susceptible to moisture.
First the pros, which I'm stating in relation to the A7S.
-Internal 4k recording. A feature sorely lacking from the original, this is a welcome addition. Several people say 4k isn't necessary. Several people are wrong. The ability to crop your videos as you see fit is reason enough to go with 4k. 4k downscaled to 1080 p also looks much sharper than native 1080p. You really can't go wrong with 4k and having it in body is awesome. I've had no over heating issues either, as seems to be the case with the a7rii.
-High Iso. It does indeed do better with noise in low light than the already stellar A7S. It seems to be about 1 stop better in this area.
-14 bit raw. I really enjoy taking photos with this camera far better now as I wasn't to fond of compression Sony used on the photos in the first model. With 14 bit raw as an option I don't need to worry about that compression any longer.
-Battery life. As somebody who does video professionally, things like battery life make a world of difference in terms of usability. While this camera does have terrible battery life ( about 60 minutes), its still better than what I would get the a7s (around 40 minutes).
-in body stabilization. Remarkable feature, that really helps your videos if your standing still. It can be a bit jerky if you move around, but I'm assuming this is just me getting used to this feature. Very happy with it. It helps tremendously taking photos in low light, as you are now able to keep the shutter speed reasonably low and still get good sharp images.
-slog 3. I liked slog 2 alright, but I love slog 3. This is the superior log. So much latitude to grade, and I'm finding it to be much more enjoyable to color correct than I did the slog2 profile. Blown out skies are a thing of the past! (with the correct exposure of course).
-autofocus. Its still worse than most cameras on the market, but its certainly better than the shot ruining autofocus of the first version. I like to use the DJI Ronin stabilizer and so autofocus is vital to me. I cant count how many times the a7s couldn't keep up with a subject simply walking forward. This camera does a much better job tracking subjects, although still far from perfect.
-customizable button mapping. This camera gets a lot of flak for the placement of the record button, however you can simply remap the record button to a better location, which is an option we did not get with the original a7s.
And now my biggest con. 8 bit. Sony claims the body is to small for 10 bit, however I can't seem to figure out why not just make the body a bit bigger. It's already slightly bigger than the a7s due to the 5 axis stabilization, and at the $3,000 price point, I don't think any professional would mind a slightly larger frame if it included 10 bit 422. With its low light capabilities and 14 stops of dynamic range, this is really the last thing its missing, and for the life of me I cant figure out why Sony left it out. They are so close to having the best camera on the market with this product, but Id say on a well lit day, my gh4 still gets the better overall image. Come on Sony, give us 10 bit 4:22 and end this battle !
Update; The menu buttons in relation to hdmi output are mapped incorrectly. I use the Atomos Shogun with this camera and learned this lesson the hard way. if you aren't using an external monitor the menu system seems to work fine. However, if you are using an external monitor, the buttons don't correlate with the action they do, which can really screw you over. I wanted to record 1080 p 24 fps for a wedding ceremony. if you select 1080 p 24 fps from the hdmi menu, it will output 1080 p 60 fps. After fiddling around with it for some time I found the solution was to select 1080i as the resolution setting. Selecting 1080i allows you to inexplicably record at 1080p 24 fps. if you select the option to record to both the external monitor and to the memory card in the camera, it will switch to recording whatever is being displayed on the a7s ii monitor (audio levels, iso, ect.) and only record to the monitor. I still haven't stumbled on the button that actually records both. I'm worried pressing the wrong button might result in launching a missile and starting world war 3. That's how incorrectly mapped this all is.
