Leave the Minox at home if you have another option for your sheep hunt. The optics are fair, but the durability and function aren't great. I took mine sheep hunting last year and the eyepiece (21-42x LER) permanently fogged up four days in. They fixed it, but then I had problems with the eyepiece being loose, the objective cover getting jammed on, and the whole main barrel unscrewing in the middle(!). To make matters worse, they send them back to Germany for service and it takes three months.
On the third go around, I asked that they let me trade it for a set of binos. I was VERY happy to see that thing out the door.
Anyhow, that's just my experience. ok glass in a far from rugged body.
