Cameras and Lenses

Close focus and eye strain



Alright, another newbie question. When binoculars list a close focus of say, 15, 10, or even 3 feet, does it mean that you should be able to look through a set at that distance and have a nice relaxed focus (low eye strain)?

Why I ask: I was looking for my first set of nice binoculars and was evaluating the EO 8x42s and 8x32s. They have a close focus of an amazing 3 feet. Indeed, they do focus at 3 feet, but my eyes were under a lot of accommodation strain to do it. It feels like I would be when I focus on an object about 3 inches in front of my nose - possible yes, but comfortable, no. Not to mention the area of overlap between the lenses is very small. Doesn't seem to practical to me, but more of an advertising item

Is this the reason the Papilios are considered so neat? The focus occurs without accommodation eye strain? I know the objectives converge to deal with the overlap issue.


Best,

You may have to adjust the interpupilary distance between the occulars when viewing very near objects. This is because your pupils actually converge for close focus in real life.


P.S. How did the 8x32 Katmais fare in your quest to date?
