Sony has a new idea to improve the image quality at very low light conditions. They propose a new tech that actually counts every single photo hitting the sensor:
“since a pixel signal is extremely weak when weak light is detected, it is desirable to reflect electrons generated from photoelectric conversion on intensity of the pixel signal while losing as few electrons as possible. In general, however, when electrons generated in a photodiode are transferred to a floating diffusion, carriers (electrons) are doped at an interface level generated due to a defect present on a gate oxide film interface (interface defect) of a transfer transistor.”
“there is provided an image sensor including pixels each configured to include a transfer transistor configured as an embedded channel type MOS transistor and to output a pixel signal based on a charge transferred to a floating diffusion from a photodiode by the transfer transistor in an on state, and a determination unit configured to convert the output pixel signal to a digital value, then compare the converted digital value to a threshold value, and thereby make a binary determination on presence or absence of incidence of a photon on the pixel that has generated the pixel signal. Accordingly, the image sensor that makes a binary determination on presence or absence of incidence of a photon on a pixel exhibits the effect of reducing influence of an interface state on the transfer transistor.”
We don’t know yet how big the improvement is. But maybe the day is not far away we will get a new A7sX with 1 million ISO 
via Image Sensor World.
The very first Full Frame E-mount camera wasn’t the A7/r. It was the VG900 camcorder. And that cam just got a $1,000 rebate today at Amazon, Adorama, BHphoto and SonyStore. I would not be surprised to see a successor coming in late March-early April right before the NAB show starts.
Super A7r and A7s deals, US boxed (no grey import) and full warranty:
A7s for $1,995 on eBay (Click here)
A7r for $1,795 oneBay (Click here).
The new 70-300mm II A-mount lens will finally ship on February 20 at BHphoto (Click here) or February 24 at Amazon (Click here). The lens has been announced back in late November along the A7II.
And A-mount camera owners should know that two more “Updated” A-mount lenses will be shown at CP+ in February:

Orion Nebula shot with Sony A6000, William Optics Scope with AstroTrac TT320X-AG Tracking Mount. Focusing was so easy with the A6000 that I was able to capture more acceptable images than with my other DSLR cameras.

During an extremely foggy week, I managed to get two nights of great photography by driving around Ocala looking for interesting subjects. This is Ocala’s nearly abandoned train station, now used only as an office for the city’s cultural director.
