I have been using the scope(3-15) for the last couple weeks. I do not find it to be typical Zeiss clarity. It functions very well and is repeatable and tracks great. The zero stop, as Jim mentioned can be set anywhere you want it but it only makes one full turn up from that point which is 16.5 MOA. Once you have it zeroed you pull off the turret and remove the black ring with the horizontal post on it. Place the black ring so the two posts touch and you will have 16.5 MOA from there. It has rubber "O" rings on the turret and the screw which should be greased. When I received mine I thought the clicks were sort of squishy and not very audible, after removing the turret I realized the O ring was forced out of it's groove in one spot and was putting pressure on the turret. Once I pushed it back in the groove and applied a small amount of grease the clicks were more positive and more audible. Just be careful everytime you remove the turret as the O ring is a nice tight fit and it is easy to get it caught on the edge of the turret and pull a small portion out of the groove.
I would say the clarity of the glass is on par with my Vortex Viper HS LR. Which is good enough for hunting but just not as clear as I would have expected. The glass on my Huskemaw
blue diamond is quite a bit clearer on 15 and 20 power. The parallex, turrets, eyepiece all function very well and the reticle is a decent thickness for hunting. Overall for a hunting scope with a 1" tube this is probably as good as it gets. If you are looking for a 30mm tube I would get a vortex or if funds allow a Huskemaw.
Again, this is only one sample but I do have leupold, vortex and huskemaw to compare it to and for function (which is my main concern) it is as good as the others, glass clarity for my eyes it is on the bottom tied with the vortex then leupold then huskemaw in my opinion.
I really like the scope and it is perfect for my 6.5 creedmoor since I use it for hunting and may be shooting 50 yards in timber or 700 yards in the sage. I can get to 750 yards in one turn so not a big problem with the limited travel.
