Hi,
Recently, I tried a Leica 82 scope. We can really saw yellow/blue franges (on top and bottom of image) looking to a dark part in the garden at 25m distance (at 50x). The colour franges appears at approx 10-15mm from sides.
In the same birding group, I had a friend whic also have a Leica APO 65mm. I decided to look through with searching colour franges.... and I found them :eek!:.
Is there anybody who noticed it too? I am surprised of my finding as the former 77 & 62 scopes were perfect (no colour franges).
Does it means that glass quality fluorite of 82/62 is lower than 77/62?.
Any thoughts?
Yves
