Since you took yours all the way off I assume you retained it. Since removing it have you seen any ill effects from removing it? Any situations where it is less sharp or you see less contrast when you have the lens wide open?
No, I have not seen any bad effects so far - I kept using it on K5IIs meanwhile. Did not use it much on FF since it was kind of front heavy on A7R and I don't really like the adapters for DA lenses.
In theory it can reduce the contrast in some situations due to reflections from the sensor (with felt on the outside, etc I assume that was its main purpose on APS-C since the rear element is anyway oversized for APS-C) but I have not really noticed any bad side effects . However, I've tried to replace it with some black tube I've made from cardboard initially and that made it noticably worse - material was not suitable for this I guess.
I will be off the grid ths weekend but I'll try to post some FF raws on Monday
