Lee I had bought a used 50 March. Bought it from a friend in PA who bought 3 of them. He told me the one he sold me was the clearest of the 3. He sold the other 2 also because he wasn't impressed with the clarity. I'll have to agree. When I looked thru my 10-60 set on 50 and looked thru the straight 50 it was like night and day. I read a thread on here some time ago about people complaining about the varied clarity of the straight 50's. I talked to Jim Kelbley about it and if what I remember correctly what he said was that Deon used 2 different coatings on their glass and 1 was way better than the other. I believe he called and talked the the people at Deon and asked why would u use two different coatings when one was more superior than the other. I'm pretty sure that they listened to his advice and that they use just one coating on all their scopes. I hope that the current production 50's are better than the older ones. I bought a straight 40 and a 36-55. I like them both, but not as much as my tactical 10-60. to me the extra money that I paid for it was worth it. If I run into mirage I just crank it back to 30-35 and it takes some of it away. When I set my flags, crank it to 15. When I shoot 100 yards I set it 40-45. 200 & 300 yards 50-60. It just does it all in my book. If your looking for a 40, my friend from PA bought a new one at the end of April and wants to sell it now along with all his Leups & a NF Comp. He tried one of those new Weaver 46's and he totally thinks that it better than sliced bread so he wants to buy 2 more. To each is own, that why we have Fords & Chevy's.
