Vortex coating must not be to the same quality as some of the other brands. Light transmission is on the low side.
Diamondback 81.1%
Razor HD 86.8%
Viper HD 81.4%
Razor UHD 86.5%
I'm not sure, but I believe the UHD is the ONLY current model AK prism binocular to NOT break 90%. Maybe it's the lowest of ANY AK prism binocular.
I'm really not sure why ANYONE would buy that thing at that price when a smaller, lighter, higher transmission SLC is available.
Couldn't agree more, especially with your last sentence. If you set a UHD and SLC side by side, both having a price tag of $1400, The SLC would get the nod every single time by anyone knowing anything about the two makers. Correct that.....one maker and one importer/marketer/seller.
