I've tried my Morpheus 12.5 & 17.5mm and I'm having trouble with eye placement. I wear my progressive glasses to observe. I've used both with the eye cup rolled down and up, along with the extension and eyecup. I find any combination to be too short or too long. I rest my glasses on the rubber guard. I've tried all combinations and the closest I can come is the guard, unscrewed 2 rotations of the 4. But that makes the thread connection very loose and I won't do that. With the M43+eyeguard I have to mash my glasses into the eyepiece and that disturbs the observation my shaking the image. I just can't find the right spot like I can with my Delos/Pentax with their infinitely variable guard.
Any ideas? I love the EPs but the annoyance of finding 'the perfect eye postion' is troubling. Lots of image drop, etc. I wish Baader had a ring about half the height of the M43 accessory ring.
