Below is a tripod mounted night image including point light source stars taken with my aligned sensor A7rM V3 and my Zeiss 35mm f1.4 ZM Distagon lens which was set to f11. The images are straight out of camera with The first image being full size; some reflection from the Sensor?? can be seen at the upper left corner. The second image is a 100% crop.

Rich,
On the first image, it looks like there is some sensor refection going on...(light on the left)
I will try some similar images today and see what I find.
Hi Fred,
That was my assessment as well as what Mike Broomfield thought when I was making comparisons with his V2 and my V3 A7rM cameras. We saw the same affect with both cameras. Also, if you look at the 100% crop image around some of the stars at least with the Kolari modded A7r cameras we were seeing a little purple to one side of the star. We were not sure if this was sensor reflection, but you may wish to check that for the stock A7rII cameras as well. Not having an A7rII I am not really familiar with sensor reflections on the new camera.

Sounds like the mod to me. I have not seen anything on a stock A7r II . I wonder now this is a guess when they took out the thicker sensor glass they left a gap with regards to a seal from the housing of the sensor and it\'s coming from there. But heck that\'s just a wild guess
Hi Guy,
Now that I also have a stock A7r, I should try a similar test with another lens that is not subject to the problems with the WA RF lens issues with the camera. Possibly it may make sense to try my Leica R 50mm lf2 Summicron lens. The exposure time on the night shot was 25 seconds. Once I have some test results I will check in.
