I've recently tried quite a few binoculars, but haven't tried any of the Minox line, other than the BV 10x25 BR.
In the store, they seemed kind of well, terrible. They were on sale for about $100. Compared to the Nikon Trailblazer 10x25, the Nikon walked all over the Minox in every way optically. (And I am not a Nikon "fanboy", either). The Minox certainly has a better looking body, and fit in my hands ok (but not great...neither did the Nikon though). The most noticable optical problem with this Minox was a lack of contrast and a lot of glare. If you see glare inside a store, things can only get worse outdoors, obviously.
I decided to buy the Trailblazer 8x25. I've had it a couple of weeks...and silly as it sounds, am planning on returning it. Despite its compact size and double hinge foldability, optically it's still quite inferior to several of the 32mm size I tried (other brands)...no surprise I guess. So I wound up buying one of those also. I may just keep that one.
The size of these Nikon 8x25's becomes tiresome to hold for more than a couple of minutes, because I'm holding with fingertips. The view is also made unsteady by this. I have average size hands for a guy. The focus knob is very tiny and has lots of play, so that also makes viewing more of a bother. But for anyone with child-size hands, who absolutely doesn't want anything bigger than 25mm no matter what, I could possibly recommend the Nikon Trailblazer 25mm series...at its pricepoint.
Sorry if this reads like a bs review, though! I'm just rattling on, I guess...my bad.
Given Dan's thoughts on the BV II 8x42, obviously not all of the Minox BV line will have the same poor performance as the tiny one I tried. It's also possible this was a poor sample, but given that these smallest of the BV line don't even have phase coated prisms, it's possible this is a factor. I'm not even sure if the little Nikon has the coating or not, but whatever it has, it clearly achieves a better result. Outdoors though, this Nikon has about as much glare as the Minox had, while in the store.
I'm envious of those of you who have the Minox HG line. That is far above my budget for optics, at least ones that don't also take pictures.
