You, however, have taken the discussion to the land of the truly bizarre. I had a very sticky focus in my Ultravid. I did not like it, it improved with time and I always focused on my target. I did not write a million rants or demand Leica fix it. My wife has an 8X32 SV that's got a tight focus. She loves it, I don't. Not my problem...or yours for that matter.Rolling ball distortion is a perception that affects some but not others. You can kick and scream about the existence of a particular wavelength of light but if I'm color blind it doesn't really matter. Distortions exist in the physical world that may not manifest themselves in the perceptual world.You can find Steve's post by reading my post. It's really very simple.Now, what's really bothering you?Happy birding!</blockquote>
