My Son bought some Leopold Yosmite 8x30s
My Son needed some binos and he bought the 8x30 Yosmite by Leopold. They are poro prisms with rubber armor on them. The depth of field is better then my 28 year old Zeiss 8x30 roof prisms. I think this might be a something that all poro prisms share. His are also much lighter than my armored Zeiss's. He was able to pick them up at Scheed's in Fargo ND for around 80 dollars.
