Originally posted by pentaxnood I am interested in lens but I am totally disappointed.
That's understandable,
but buying a new lens three years after it's discontinued
will be something of a gamble.
You're lucky to have located a copy at all.
Originally posted by pentaxnood Well in the lens box it said something like 'Specially exclusive for Japan'
I don't know what that would mean.
Originally posted by pentaxnood (and on lens it says it is made in japan ). I saw something like Cosina too in the box.
Yes, these Zeiss lenses are made by Cosina, with Zeiss quality control.
I have several Zeiss and Voigtlaender brand lenses made by Cosina,
and have been very satisfied with them.
Originally posted by pentaxnood I ll ask store to change it if they have another one. Do you think this specific malfunction is covered by warranty?
If the lens's paperwork is in order, yes, I would think so.
Even if it's not just a hard infinity adjustment,
but something more complicated like the floating element system,
that should be covered under the Zeiss guarantee.
