The focus on my Dialyt 7 x 42s was stiffening up a bit so I shipped them off to Zeiss with a covering note. Sent them off last Tuesday so I guess they got them on Wednesday. Friday I got a call from Gary saying the focus had been sorted and the general health checked over. They came back the beginning of this week, clean and shiny and with silky smooth focus. No charge! Gary told me they were made in 1993 and was generally very helpful. Once again, fantastic service!
