Hi,
As you have probably noticed the housing is not metal and so could possibly have taken a knock and cracked. It should be a very simple repair - unscrew the objective lens mount, unscrew the broken tube, screw in a new tube, screw in the objective mount, adjust focus and fill with nitrogen. Milton keynes could have sorted it out in a day or two.
Unfortunately all the service staff (myself included) have been made redundant as Leica UK is concentrating activities around the London shop and none of the MK service staff were moved there. This also includes the service admin. staff who would normally have taken your call. All repairs , except minor jobs such as replacing eyecups and cleaning external optics, will now have to go to Germany.
I am now fortunately working for another German alpha optics manufacturer who appreciate the importance of UK based servicing facilities.
I will be at the Birdfair next week and would love to see those of you that know me.
Gary.
