Re: A thinner sensor stack may be possible after all!
Another observation that has surprised me is with the Loxia 35 with strong back-lighting @ f/2 there is considerable CA with the A7II, and is negligible at f/2.8. However from some more testing this morning (sorry no direct comparisons.. yet) that with the A7r Modified there is virtually no CA with the Loxia at f/2.0. Personally for myself using the lens for portraits at f/2.0 is great, as there is not correction for CA needed in high key/backlit shots. Yet with the A7II there is considerable CA at f/2 that needs to be corrected in post.
I would be interested in others observations. I do feel that the thin filter modification will also behave differently on the A7 and A7r.
I would also be curious if anyone has tried the mod on the A7s? At the moment, the A7s is still my favourite to go camera so I\'m waiting for some feedback
I have just added a photo with very strong backing, shot of glass candles no PP or corrections with +3 exp compensation which would show considerable CA at f/2 with A7II. The A7r Mod seems to keep the CA very well in check.
