Thank you for the review. Leupold do not get much of a mention on C.N.'s obviously because they do not make the large astro size versions.
This is a shame as they do deserve more attention.
The one thing I notice from the specs. is that the Olympic 10x50's roofs have a 5 degree FOV which is a 50 degree Afov - did you find this 'restrictive' at all or was this not noticable ? It does appear from your review that most of the image is very usable with a minimum amount of aberrations and distortions.
The Olympic roofs along with the Cascade roofs are Japanese made. My Acadia 8x42 roofs - which are a level below the Cascades - are Phillipine sourced. The Acadias are impressive for a more 'entry' roof bino with a wide and usable 7.5 degree FOV.
