There isn't much info on the minox 15x58 around. I have looked alot and on this site there are a couple guys who have owned and commented about them, pretty much the only comparisons I have found anywhere.
I have some steiner senator 20x80, I was thinking of upgrading to minox or swarovski 15x56, but hanv't had to oppurtuntity to see either first hand.
I just called the outdoorsmans.com (by the looks of the custom made pistol grip and tripod they have designed made themselves I can assume they are pretty knowledgable about glassing).
Ok here i go repeating what the other guy said...........
The salemen said the minox are 95% the binocular, very close optically but if you look hard you can notice the swarovski is sharper, swarovski is tougher, minox has a usa service center for warrantly work(when i asked about the long turnaround times for warrantly work I had read about he said somtimes they have to ship them back overseas). He also said to his knowledge minox is not discontinuing them, someone has posted here that they are being discontinued??
