The price goes down ...
since the first time I paid almost twice the price last year.Most of the old Leica are limited in close focus and this marvelous adapter transform most of your Leica lens in today standard close focus distance.
And the ring of the adapter can also be use to focus for example on the 40mm 2.0 where the tiny front focus ring is difficult to manage on the Sony NEX body.
When I have time (always the problem ... ) I will shot you some test with the Leica 40mm 2.0 & 90mm 2.8 & the Canon 50mm 1.2. This is bad there is no equivalent for the old Contax RF mount so far ...
