I think it can be "measured" very simply. Take a soft lens, mount it on MZ-6 and try to bring it to focus manually without electronics helping you. Then, mount same lens of *istD. In my case (-6 dptr in each eye and constant glasses), *istD works marvels compared to MZ-6. YMMV of course. Boris mailto:[EMAIL PROTECTED]
