Actually I did order the 2.7 but got the MTL (2.7 is on it’s way to me, thanks to brilliant customer service from John). Couldn’t wait so built the MTL.
I was expecting it to be a little tight for me due to it being only 1.8, 2.2 is my preferred size, but it’s actually really, really good, using the largest hole on the ring.
Still looking forward to trying the 2.7 but until then it’s working nicely for me, very similar to a KF3 mini with no airscrew, just a tad tighter but not much.
Definitely looser than the True or a KF5 with the 1.8 reducer in it.
