I have the Pilla
panther X6 Post 10 year old style frames. the current panther x7 lens's will work on the old frame.
They have an adjustable nose piece {post} to move lenses up & down
The
52CHC made by ZEIS lenses are an outstanding all around lens color for trapshooting, benchrest shooting & pistol shooting!
The crosshairs will not shift around while looking through them.
Spend a little time on Pilla's web site and research their lens description {color, high definition, high contrast, light transmission}.
52CHC
52=52% light transmission
C=Chromashift color {makes the red rings in benchrest score shooting & the orange color clay target for trapshooting really standout!}
HC=High contrast
I also have a lens that enhances the orange clay target color 200% {make them look like the size of trash can lids}
I have never had an issue with the lenses fogging up! the folks that live in the southern states with high humidity I could see them maybe having an issue.
L&M Lenses {
https://lmlenses.com/ } sells several different brands of shooting glasses and will work with you & your shooting needs
I have zero regrets of buying them! they have served me very well for the last 10 years!
If they get broke or I lose them. I would buy the same thing in a heartbeat!
Good luck!
