Just curious about something. I've kinda been looking for a nice gloss Leupy or other similar quality variable in 3-9 or 4-12x40 and I've really gotten used to the side focus that I have on some of my other newer scopes but that feature seems to be hard to find on the older gloss scopes. Does or did Leupold or other quality scope makers make these or is the side focus more of a modern feature that came along after the matte finish scopes became the norm. Thanks!!
