I have been repairing optical and photographic equipment since 1963 but now concentrate on binoculars, telescopes and microscopes. Repair / alignment costs.
A standard porro prism binocular is likely to cost around £50 to re-align whilst a clean / service and align will be around £60 A roof prism model may cost a bit more, maybe £60 to align whilst a clean / service and align will be about £82. Postage is extra. I can also renew the tripod thread on a telescope using a steel helicoil for £24.
Please phone before sending an item for repair to make sure it is one I can do. Land line 023 8084 2801 Apple mobile 0740 259 0740 Android mobile 079 77 88 1482 with hands-free in car
