Hey, I have the wonderfull Olympus 12/f2.0 lens. It takes stunning and sharp pictures and I am quite happy with it. This was until I tried to do some night time astro shots. As it turned out, I am not able to focus to infinity when the focus ring is pulled back (i.e., manual focus is activated). When I turn the manual focus ring towards the infinity mark, 5 meters and beyond objects are still not in focus (at f2.0 - tested in daylight). Going past the infinity mark on the lens improves it a bit but objects still are not in focus. When the lens hits the physical stop of the focus ring, the focus plane is roughly about 3 to 4 meters away. The lens, however, is perfectly capable of focusing to infinity. When using AF or MF (set in camera with the focus ring NOT pulled back) I can focus without a problem. It seems, that the pulled back focus ring is completely off. As I learned on the net, the lens is never physically focused by the ring. Twisting the pulled back ring is only an input to the focus motor. Hence my question: Is there a way to adjust the input coming from the pulled back focus ring (e.g., through software)? Has anyone of you the same problem? Just for completness sake: I am using an E-M5. Also tried it with my Oly 12-40 and there everything works as expected, which means I can focus to infinity and beyond using the pulled back focus ring. Thanks in advance for any insights on this matter!
