I had a problem with objective lens misting on one of my conquest scopes. You get lifetime worldwide warranty, but only Zeiss US can service them. Procedure is to return the scope to place of puchase and then it gets sent to Zeiss. I guess it is to avoid duty charges. I just sent the scope to the shop I bought it from and they dealt with the rest. Original proof of purchase was attached and parcel marked as warranty repair and I never got charged any additional duty fee. All took 3 weeks including shipping. Very pleased with the service. I know it is a bit pain in the neck, but I knew that before I bought it. It was best scope for the money at that time, even including hassle with warranty repair. Both scopes have target turrets and no problems with tracking.
