does the adaptor sit inside the sony mount? some adaptors sit out side and you lose the infinity stop. i was looking at a few mirrorless systems and that is a priority for me.
The adapter for the NEX system is outside, because these full frame lenses need the offset for the NEX sized sensor. I have not read any infinity issues when using the legacy lenses with the NEX. Plus the NEX has a really strong focus peaking feature to ensure focus.
