What I have learned lately is that setting the diopter well seems to make a big difference to my eyes, and they haven't been great lately-watering like allergies are making them irritated, which isn't helping my viewing of course.

I also found that under certain lighting conditions, items appear not to be as sharply focused (bright overcast) as they are in better light (partly cloudy), but using the same binoculars, so now I know it's not the binocular. But rather the lighting, and my eyes at times, and other times, the diopter settings that affect the apparent sharpness and quality of the view. And of course, IPD and eyecup settings too.

So I have learned some important things from this strange view I first experienced with a new pair of bins, and not to jump to conclusions about it until I checked all the variables I now realize contribute to this, in any bin, whether roof or Porro.

I should probably buy Bill Cook's book to learn more about binoculars in general, and some other fine points about their design and usage. I would like to know a little more about the differences in designs that affect
what we see and why. Got anything like that in the book Bill? Sounds like Chuck really enjoyed it!
At this point, you won't find a great deal about the various designs. But, have a look at what readers are saying and determine if it would be helpful to you. Iíve given all this stuff away MANY times. So, if you are willing to scour several bino forums post over the last 15 years, you can have the whole thing ... free. Thatís kinda like wrecking the car to turn the radio off. But, hey, itís an option.
