Can't say exactly what or why but the III F fits like an old pair of comfortable jeans. With the Summarit, is it a lovely piece of jewelry. But in low light, the VF (both viewports) need cleaning inside. The focus window shows some white stringy material under a magnifying glass that causes some ghosting and makes it difficult to see at times. The framing window has a lot of little "dots" of something in there but it isn't really a problem.
The eyepiece has two screws. Is it tricky to take the eyepiece off? Is there something else to do to get in there and clean these windows out?😕
