That is correct. It is not a speed booster just an M to E mount adaptor with a helicoid built in. The 40mm has no focusing element so it requires an adaptor with a helicoid etc.--Just to be clarified, that close focus adapter does not act like a speedbooster right, so you still get the crop factor when using those lens on your A6000?

So the crop factor equivalences for the 3 would be:
22.5 / 60 / 112.5
... on the a6000 but, I really don't think about crop factor much at all.
Maybe if I add a full frame body to my kit the differences will gain more meaning to me.
The adaptor does allow for a much closer minimum focusing distance as an option though.
On the 15mmm I think it drops from ~1 meter to like ~10 inches but, I can't find the little chart which shows the differences for the CV line of M mount lenses.
Either way it allows for an entirely different shooting experience using the same glass and makes the idea of investing in the E mount CV lenses an interesting debate for me
