Just some info regarding Leica service.
Applicable for Leica UK Sports Optics sales
There is NO lifetime or 30 yr warranty on Leica sports optics in the UK.
Any warranty for Leica binoculars is for the original owner only and is not transferraable.
Leica charge a minimum of £65 for a repair/service estimate.
I found this out the hard way having purchased a second hand pair of Ultravid 8x42 BAs which had several problems. Thry had scratched optics, some internal haze and a pungent chemical smell from the rubber armouring.
They were forwarded to Leica in Portugal and I received two estimates. One was for 'essential work' £189.25 involving rearmouring, internal clean and recollimation. A second estimate for £319.25 was forwarded for 'desirable work' which involved replacing the objective and eyepieces glass and replacing the eyecups.
I went for the more expensive option.
The good news is that they were overhauled and returned to virtually 'as new' condition. They had all eyepiece and objective glass replaced, new eyecups, fully rearmoured, the internal assembly cleaned,recollimated, regassed , fully serviced and returned via a premium DHL International courier.
I have a feeling they may have upgraded the optics because there was a distinct lack of Chromatic Aberration when returned. There was little to start off with but seemed to have become virtually zero, even with very high contrast situations ie magpie in brilliant sunlight perched on a white wall.
Leica performed the service and repair work to a very high standard.
