It is aggravating to pay a premium price for a premium scope, then have to pay even more to make it useable.
My next Swaro will likely be a VX-6...
No problem with that Duplex. And the glass quality, IMO, is somewhere between a Z5 and a Z6, probably closer to the Z6.
I've compared my VX-6 2-12x42 with my Z3 4-12x50 BT and my Z5 3.5-18x44 BT and the VX-6 to me is the winner. And the Swaro scopes are very good, the VX-6 is just better. I don't have a Z6 to compare it to, but my Zeiss Victory doesn't really seem any better than the VX-6.
No elaborate testing protocol, just my best guestimate from looking thru and using these scopes.
