Oh hmm, yes in the case of the G90, it does have a very reflective "backside" that normally wasn't exposed at all on the G cameras. So that makes sense. Though, what's the light initially reflecting off of, if not the sensor? (happens with the sun out of frame, so it can't be hitting the sensor initially).
I don't recall ever seeing this with the Nex, and the back-of-lens situation was the same.
Very good question. It's such a strong reflection off the interior barrel that I think it must be from the primary incoming light. Perhaps the image circle is a little bigger than FF and reflects back on to the edges of the sensor? The g35, OTOH, does not have any reflection issues with the same adapter, even when pointed near the sun.
Prior to blacking out the adapter barrel, I tried blacking out the g90 brass contacts and shiny lens base to no avail. All the reflections are coming from the adapter barrel, whether primary or secondary. I doubt if they are sensor reflections in this case because they are SO bright, and only occur with rare lens/adapter combos. This effect is different than the nighttime internal reflections around bright objects, which seem to occur in both NEX's and the a7/r. Those seem to be some sort of sensor based reflection issue.
It's really odd. I noticed the "reflection flare" in almost every g90 shot I took, then saw online shots from the same combo that seemed fine. So...I focused on the adapter as being the issue.
I ordered the metabones because it seems to have a very nice matte internal coating. We'll see how it does when it arrives later this week...
