Sigma APO's

["Willem-Jan Markerink" <w.j.markerink@xxxxx>]

Dear gang,

I just spoke to a Sigma rep, who claimed that their APO's didn't need 
focus correction for IR either.
I hesitate to believe that right away....the guy said the deviation
was too little to put it on the DOF scale....so the question is: has
any of you ever run (focus) tests on HIE with a Sigma APO at full
aperture?

     the inability to understand
