Great question, I have not owned the Vortex but I have tested it outside when I was purchasing and It has great glass and clearity. With that said I went with the Ziess 85 with the larger eye peice 20-75 this scope is great the clearity is fantastic and having the extra range is great. It carries it edge to edge with great contrast and color definition.
You are referring to the retractable Meopta? Optically it is very nice with a nice flat field, excellent contrast, and good resolution. I understand that a guy can use them in the field without issue, but weatherproof sealing is a deal-breaker for me.
I just got my Razor HD 85mm spotter and it is amazing! I have been looking at elk by my house the last couple nights. I got it shipped to my door bran new from ElkNut cheeper than the price you have listed. Get a hold of ElkNut and he will hook you up.
