I'm getting this wierd thing in the last frames. Sometimes in the 11th frame.
Always at the same side. I think it happens only when using relatively open apertures (5.6 and below).
I though it was a flare and started to use a hood. It didn't help.
The camera I'm using is Relleiflex 3.5E with Xenotar 75/3.5
An idea? Anyone?
