90 had the least amount of lag.
It's not that bad, and does recover quick, and as soon as you stop on something it refocuses. The more and more I play around with it the less distracting it seems, if this makes sense?
It really is nice to be able to use it during the day, especially to zero in an IR laser and not have to wait to get out to some place where you can shoot at night without having SWAT called on you
Also for a newbie idiot like me there is lesser of a chance of degrading a tube due to newbie mistakes.
Under no ambient light or very little with this thing you will definitely need IR illum. I wonder if this is the case with Gen 3 also?
I mean when you have no or very minimal ambient light all you will see is just barely the outline of objects close to you but mostly static like a black and white TV set on no channel. Hope I am making sense here?
