I have in mind this 2 different scopes for a medium range .264 win mag deer rifle. The first is a swarovski Z3 4-12X50 BT and the second one is a Kahles 3.5-10X50TDS Reticle. Which one do you believe has better optical quality?? Never owned any of this brands before. I have a Zeiss Victory HT 2.5-10X50 on my deer gun and love it, but it costs more than twice than this 2 so I really can´t afford it right now.
