[QUOTE="Pdvdh, post: 157764, member: 4191"] [b]Re: IOR SCOPES - light transmission ~ light gathering[/b] I also have read praise regarding the light transmission of IOR scopes but it has always been a 2.5-10x IOR or one of the other IOR 4X power magnification scopes. I've read a lot of forum posts including Snipers Hide, Snipers Paradise, 24 hourcampfire, and many articles, and don't recall a single post or article where anyone has done side by side light transmission comparisons with an IOR 6X power magnification scope. If you're aware of any, I would appreciate your posting the web address so I can take a look. A buddy and I went out one winter evening and compared the following four (4) scopes for light transmission, one being my IOR 3-18x 42mm. We both came to the same consensus, from brightest field of view to dimmest field of view. We did turn all scopes to the same power setting for this comparison. 1st - Zeiss Conquest 4.5-14x44mm - Brightest, no doubt about it. 2nd - Leupold LPS 2.5-10x45mm 3rd - Leupold VX3 2.5-8x32mm - Similar to IOR. 4th - IOR 3-18x42mm - Dimmest (Similar to the Leupold VX3). If the 6X IORs are about the 5th best in light transmission then my comparison couldn't prove it. But they may rank highly against other equivalent scopes that also magnify over a 6X power range.
