Sony Alpha A7S II Frequently Asked Questions (FAQ)
What is the difference between the A7S and the A7S II?
The A7S and the A7S II share many of the same features; sensor resolution, ISO range, recording codecs, etc. There are, however, a few key differences between the two cameras. The A7S II has internal 4k recording, 120fps full HD, 5 axis on sensor image stabilization, S-log3 and S-Gammut3, more auto-focus points, and improved ergonomics over the original A7S.
What is the difference between the A7S II and the A7R II?
In many respects the A7S II and A7R II are essentially the same camera. The biggest difference is the resolution of the sensor. The A7S II as a 12.2 megapixel sensor while the A7R II’s sensor is 42 megapixels. The A7S II has more options for log shooting with S-Log3 and S-Gammut3 in addition to S-log2 which is available on the A7R II. The last big difference is that the A7S II is able to shoot HD up to 120fps.
Is there an issue with overheating?
Under certain conditions the A7S II and A7R II cameras can overheat when recording 4k internally. This is more likely to happen when the ambient temperature is higher. The good news is that your footage is still written to the SD cards before the camera shuts down. At least in our experience, no guarantees.
Is the HDMI output 10-bit?
No. It is however Uncompressed 8-bit 4:2:2 instead of 4:2:0.
What kind of SD cards are needed for 4k recording?
Both the A7S II and A7R II require SDXC (64gb+) cards that are UHS I speed class 3. We recommend using SanDisk ExtremePro cards for the best performance and reliability.
How do I get into log mode?
Unlike other Sony cameras finding the log settings on the A7 cameras is not very straight forward. The log settings are under the Picture Profile menu. Picture Profile 7 is S-log2 (A7R II, A7S II), Picture Profile 8 is S-log3 (A7S II), and Picture Profile 9 is S-Gammut3.cine/S-log3 (A7S II).
How long do the batteries last?
It depends on how you are using the camera, but generally each battery will last for about 60 minutes. If you are recording with an external recorder the batteries will last about 90 minutes.
How long does it take to charge a battery?
About 90 minutes for a full charge.
Can I use my old lenses?
The answer is likely yes. One of the greatest advantages to Sony’s E mount system is that it has a very short mount flange to sensor distance, much shorter than most other lens mounts. The A7S II and A7R II can be adapted to work with modern lenses like Canon’s EF mount or Nikon mount lenses, and you can get adapters for older manual lenses like Olympus OM, Leica R, Nikon, Canon FD, or 42mm screw mounts. The one thing that you do need to be conscious of is whether or not the lens will cover a full frame. Most modern professional lenses will, and nearly all older lenses will.
How long can I record for?
Like all DSLR’s the A7S II and A7R II are limited to 29 minutes and 59 seconds of continuous recording, regardless of codec, bit rate, or media space.
