Similar experience with servicing a 3x9 scope that lost nitrogen. Zeiss claimed the tube was bent which make no sense since it would have lost charge shortly after mounting... not years later. I don't hold alot of weight on warranty when making purchases.This is a forewarning to anyone who is considering buying Zeiss product(s), in part, because of the Transferable Limited Lifetime Warranty.
I have multiple Zeiss Diascopes and Victory line scopes. I have never needed to request warranty repair from Zeiss, which is a very good thing indeed. One of the oculars for an 85mm Disacope developed a small opaque “globule” on an internal lens. The globule was static indicating that it was not water. I tried a number of possible solutions, i.e., placing the ocular in a bowl of dry rice, storing it with desiccant, etc. Naturally these efforts were fruitless because the ocular is waterproof.
Because I have multiple Diascope bodies and eyepieces to choose from and Zeiss has a Limited Lifetime Warranty I wasn’t rushed to send in the ocular for warranty repair. The warranty states in relevant section:
Limited Lifetime Transferable Warranty
"ZEISS Sports Optics Optical Systems are warranted against defects in workmanship and materials for the life of the Product.
The Optical System means (a) all the components between and inclusive of the optic’s objective and ocular lens, and (b) any functional and mechanical operating system associated with the optical performance of the Optical System.
If a defect covered by this Warranty is found, ZEISS will, at its sole discretion, repair or replace the Product with a new or reconditioned ZEISS product of comparable specifications."
The response I received was surprising: “We have completed the inspection on your Vario-Okular 15x-45x/20-60x, Serial # *****40 and have determined that your optic is either beyond economic repair or not repairable.” And with that, Zeiss would not honor the lifetime warranty even though Zeiss did acknowledge that it was not due to consumer abuse or mistreatment.
I spoke to Joseph “Joe” Israel at Zeiss whose offer to resolve the matter was to sell me a used Vario-Okular at retail price but without a warranty. He went on to explain that "Lifetime" does not really mean "Lifetime" but rather what Zeiss holds to be a reasonable period of time.
Needless to say, I will no longer be purchasing or supporting Zeiss products. Swarovski’s warranty and repair department has handled all my warranty issues without pause or issue. (the range finder in a pair of Swarovski El Range stopped working. Even though the binoculars were beyond the five year warranty, Swarovski fixed the issue and at no charge. I was fully expecting to have to pay for the service and repairs because it was outside of the warranty. The point being, one manufacturer stands behind its products, even if outside of warranty coverage, and Zeiss refuses to stand behind its lifetime warranty.
