This camera is in excellent overall condition showing only light signs of use, and the camera screen is pristine with absolutely no marks on it whatsoever. A new tempered glass screen protector has been applied to keep it this way.
The A7S-II has larger pixels than pretty much any consumer level full-frame digital camera. The larger pixel size means that each pixel can physically collect more light. The more light per pixel, the better the signal to noise ratio for that pixel and so that pixel will more accurately detect the incoming light than a smaller pixel would. This means that, all other things being equal, the A7s should be capable of the best per pixel signal-to-noise ratio of any production camera. This means that it should arguably be the best camera for astrophotography.
The Sony Alpha A7 is a part of the Sony Alpha Series, Sony's full-frame mirrorless camera range. The whole range shares some features but each thread of the Sony Alpha Series (R, S and regular) prioritises one aspect of photography over another.
- Sony A7 R cameras prioritise Resolution over Speed (heavy cropping can be done without losing too much resolution, but you are compromising some speed).
- Sony A7 S cameras prioritise Sensitivity (Speed) over Resolution (magnificent in low light situations at high ISO's due to the larger light gathering sensor pixels). ISO 100-102400, which is further expandable to ISO 50-409600. (A killer for Astrophotography).
- Sony A7 cameras prioritise Hybrid Shooting which is in the middle of the two - the best of both worlds!
This
camera has been professionally converted to "Full Spectrum" which makes
it rather fun for dabbling in infrared photography. To do this, the
IR/UV blocking filter has been removed from the sensor allowing the
camera to "see" light wavelengths that the human eye cannot. Because it
has been converted, shooting in infrared is hand-held just as in regular
photography unlike unconverted cameras which require long exposures as
the camera can't see the IR properly.
I have included the four essential filters, a very special absorption type IR/UV blocking filter for the front of the lens which replaces the filter removed from the sensor. This allows you to continue to use this camera as a "normal" camera, and swapping this filter for the supplied Aerochrome (IR Chrome), 590nm and 720nm IR filter opens up a whole new world of fun.
So, everything that you will need is included. These filters are brand new.
Two genuine "Sony" batteries are included with a twin-bay charger. The batteries can also be charged directly in the camera with the supplied USB cable, and it is good to do it this way from time to time as it also tops up the internal back-up battery.
The shutter count is 62,004. (Average rated shutter life is 200k shots). This is slightly higher than on most cameras that I would generally offer for sale, but this is still not considered as high (150k+ is high), and this is reflected in the price at £150 below my regular price for this camera with a lower shutter count.
Firmware is up to date.
It works perfectly (as expected) and comes with everything seen in the images including a nice quality canvas "Crumpler" bag, 32gb SD card which can hold over 5000 full res JPEG images and a USB SD Card Reader.
All my pictures are of the actual items for sale, so what you see is what you get.
Ready to go straight out of the box.
You won't be disappointed!
Condition Meanings: Pristine - No obvious signs of use, as new.
Full Spectrum Care:
We focus on quality and longevity. Every camera we convert goes through a full diagnostic check - we test every component, and if something isn't right, we fix or replace it. So, the goal is to make sure it keeps working for years.
That level of care, combined with experience, is what keeps people coming back to us. We're not just swapping out filters - we're refurbishing and upgrading these cameras to a professional standard.
· Every camera undergoes a full multi-point diagnostic check
· Faulty components are repaired or replaced before conversion
· We calibrate infinity focus, ensuring compatibility with any lens
· Specialising also in high-end Sony models: A6000 series, A7 series
· Each unit is tested and tuned for long-term reliability
· Direct support from who performs the work - no outsourcing
In these Sony cameras, the sensor sits on shafts that are calibrated for each specific unit - not just the model, but each individual camera. We measure these shafts with 0.01 mm precision (10 microns) and adjust them so the camera can properly focus at infinity. It's a process that requires experience.

If
you are new to IR photography, you will need a photo editor in order to
properly white balance and colour swap the red and blue channels for
the desired colour balance effects and blue skies. Without editing you
will not have good pictures. I can fully recommend
"Raw Therapee" which is free and does everything. This is what I use
myself. Once you get the hang of it you will find it easy to use, and
there are plenty of tutorial videos online. Another editor that is
commonly mentioned is "Gimp", but I have tried them both and much prefer
"Raw Therapee" as I find it easier to use and seems to do everything.
It seems to be "more complete" as Gimp doesn't seem to be able to process RAW images.

Questions & Answers:
Q: Can I still clean the sensor as I normally would on your Full Spectrum cameras?
A: Absolutely you can, the sensor is not "naked". Under the filter that has been removed from the sensor remains a very hard permanent factory fitted glass which protects the sensor.
Q: Will the camera still focus properly at infinity after a conversion?
A: In these Sony cameras the sensor sits on shafts that are calibrated for each specific unit, not just the model, but each individual camera. We measure these shafts with 0.01 mm precision (10 microns) and adjust them so the camera can properly focus at infinity with any lens. It's a process that requires experience!
The other option would be to replace the removed filter stack with material of equivalent thickness, but this is not how we do it! This involves using optical glass or performing a permanent fixed-wavelength conversion (e.g., for 720nm or similar). It's a tricky method, and image quality can suffer depending on the quality of the replacement glass.
