Pics and specs from Zen-Ray site.

Their ZRS, with a FOV tweak, looks like a Vortex Viper clone.
ZRS is interesting. 10x42 has 60 degree AFOV, whereas 8x42 is slightly narrower (58ish). It seems they might have put a field stop on 8x42 to maintain its edge resolution. The spec also says 5 piece EP and 3 piece objective lens (a semi-APO triplet design?). Adding the focuser lenses, we are talking about 9-10 glasses. If quality checks out good, it will be an awesome deal for under $200 (they are running a promotion with a $35 coupon ("ZRS")). I might just get one of those.
