Zeiss.
A friend asked me to repair his rifle which had something heavy, maybe a horse and saddle fall on it. The Diavari 3x9 was ruined, the objective bell was out of round, main tube bent, a real mess. I replaced it with a Weaver I had so he could get hunting again.
I took a chance and sent the Diavari back to Zeiss asking for an estimate. Three months later it showed up good as new, no charge, fixed under warranty.
BTW, the boys over at the 24HCF have been complaining about Leupold quality going downhill the last few years. I haven't bought a new one in quite a while and can't comment.
