How to fix Zeiss dialyt 10x40 B?
Posted 17 February 2019 - 04:00 PM
The diopter setting needs to be set far into the negative, eventhough I observe with glasses. All other bins I look through require almost no adjustment. It makes me think that something is off inside?
There is play in the focuser which is annoying. I mean that the focusing wheel turns for a bit before the focusing begins to change.
The first issue is not a big deal, but the second is super annoying.
Can anything be done about this?

I am going to guess that NH in your address stands for New Hampshire. I would check with Zeiss USA to discover if the binouclar is under guarantee. If not, I would consider sending the binocular to a qualified optical technician.

These are pretty good units, at least the 12 Zeiss 50mm objectives I bought from Gary Hand for $3 a unit were. I'd be surprised if they don't have an adjustment for the main focusing helical.
As for the diopter adjustment you're talking to the wrong guy. It takes me two stacked TV 1.8s to get close=8(

I can help with the play in the focuser, as I have had experience with 2 of these with the same malady.
My experience is with the newer BTP models, and yours may be much the same. On the focuser knob, the
cap is secured by 3 tiny screws, and needs to be removed with small precision screwdrivers, you may have a
set, they are useful around the house for eyeglasses, etc. Remove the cap, and then you will see a larger bolt that
will tighten the focuser itself. Try to tighten this to your liking, replace the cap, and you are set. I hope this works
As for the diopter, I have no advice there. If you can tighten the focuser, and can get along with the diopter I
would not send it in. Zeiss often has to send these back to Germany, and a call to their service center could help
to see if they will warranty it, and they might.
Good luck, and let us know how it goes.

Not sure if I can make them move. Any suggestions?

Zeiss stands behind their products 100% no matter if you are the original owner or not. They will fix it free of charge. Let them.
(At least that's the way they operated in the 20th century. One of the few truly stand-up customer-supporting companies left in the world.)
