Fugl,
I found the fully extended eyecups on the 8.5x42 EL to be slightly too short for my face, which caused the same effect you describe. The eyecups can be unscrewed a little beyond the normal fully extended position without falling off and I recall someone here with the same problem replacing the eyecups with 7x42 SLC cups which are longer.
I used this binocular for about six years. IMO its greatest virtue is that no optical characteristic is significantly weak, but at the same time no optical characteristic is fully state of the art either. I'm waiting for the new EL, which does have the potential for best optical performance in every category, except perhaps light transmission since that will still be slightly compromised by the Schmidt-Pechan prism.
