Thanks. I also thought they are talking about new lenses.

Was interested in their 50 and 85, looks like it will be better to wait till they update these two.


The 85mm needs no help from the new testing regime.  It's pretty well built already and delivers great results... and being fixed focal length is pretty easy to properly set a good microfocus adjustment if you need to (I did not need to on my SD-1).  Just because they have a more rigorous process in place does not mean they were not already building higher end lenses very carefully.

It is an awesome lens, well worth buying now...  I think it would be a while before they update it as it works pretty well already.

The 50 you may want to wait for an update, or buy a DP-3M which has lots of other benefits (like even more amazing sharpness and a sync speed of 1/2000).
