Two Great Truths About Optics

I’ve written a lot of magazine articles about optics, and for several years I even wrote a continuing optics column. I don’t claim to be an expert, but I know a little bit about optics. At least, I thought I did. Just last week, at the annual Outdoor Sportsman Group “round table,” Zeiss’s Kyle Brown gave us an update on new products. He started with two very astute comments.

The first one I’ve said wrong so many times that I’m embarrassed: “Optics don’t gather light; they manage light.” The second is something that I have long believed, but Kyle said it better and simpler than I ever have: “Magnification is over-rated!”

A couple of weeks ago I was at the range and I felt really silly. I was shooting a Marlin lever-action “guide gun”—very tricked up, but still a .45-70, and I had a big variable scope on it, 30mm tube with large objective. Before you judge, I had a reason for doing this: the rifle seemed to be accurate, so I put a powerful variable on it and turned it all the way up so I could see how well it grouped. I would never hunt with that much glass on such a rifle. Range work done, I took the big scope off, mounted an Aimpoint red-dot sight, and took it pig hunting.

This Marlin “guide gun” has a very good ghost ring aperture sight, but as middle age advances all open sights are getting harder to see. As an alternative I mounted an Aimpoint red-dot sight, a truly excellent type of sight for shots out to perhaps 150 yards.
