Like others have stated the Zeiss Conquest
glass will outshine the Leupold. Better clarity, resolution, color, contrast and light transmission.
They are limited in terms of internal adjustment, however a good 20moa base (either one piece or two piece) would cure that problem. There are plenty quality manufacturers that are making a solid 20moa base including Talley
, US Optics, Seekins, Warne, and EGW just to name a few.
I don't see them doing anything affordable in the 30mm tube anytime soon coming from Zeiss. If you want to go 30mm the best alternative would be Meopta
(they assemble the conquest btw. Everything from the glass to the components to laser etching the bodies). The only draw back to the Meopta would be no bdc reticle.
