I got a Voigtländer Vito BL recently. I tried it, and noticed that some of the photos came out with a big light circle right in the middle. I have tried searching for circles, stains, orbs, etc., but I haven't found circles as big as these ones. Does anyone know why this happened?
Both photos were taken with raking light. Both have multiple smaller artifacts. The primary artifacts are not on all photos. The camera dates from the late 1950's before more modern lens coatings were common. I suspect that it is internal reflection. The washed out nature of the primary artifact is consistent with that as are the secondary artifacts. I recommend a lens hood as the first step toward resolving the issue
