    Tonight it isn't...well, maybe it is with this Nor-Easter going through. Tomorrow night it most certainly will be. I will prepare a setup to test just this issue. They all have valid manufacturer's warranties though right? ;)

    Uh, yeah, I'll pass. ;) As for the other two, I would not have a problem doing either though it is supposed to be fairly cold tomorrow night and Wednesday with wind chills down into the negative double digits. If that isn't a test then I don't know what is.

    Good point. I look at this issue from two perspectives. One, even if they drop the ELX I have a feeling they will honor whatever warranty issues arise. If not, and you bought the glass from Doug at CLNY, then I have a feeling he would do his best to make the issue right for you. Two, not to...

    10x Promaster and Frontier

    Hmm, interesting but not surprising. I found much the same thing with the 10x and 8x Vortex Razors. I loved the 8x version but was less than thrilled with the 10x. I wonder if this is a question of needing tighter manufacturing tolerances for the higher magnification or just that the 8x42...
