Been looking at the 3-9x40 Zeiss Conquest and the 2-10x40 Minox ZA5. To my understanding they both use the same glass? Both of these are close enough in power range for me to not be bothered by either of them...I would choose either one on this factor...but what pros vs cons do these two have compared to each other...or are they so close it wouldnt matter which one i purchase?
