Looking at investing in a new pair of binos. A buddy of mine really wants to buy my Leica Trinovid 10s, which I’m willing to do. My question is...is it there a significant or worth wild difference between 10s and 12s for me to jump up to 12s. Pros and cons? I’m a big Leica fan, have the 10s and a pair of 8s. I’m just looking to see if weight, power, etc. is worth the price difference to jump up? Can you manage 12s freehand or are they going to be a little shaky? Any thoughts appreciated!
