When I'm using my voigtlander 40mm f/1.4 (single coating) on my R3M, i'm getting quite a few frames with some unusual flaring.
Most pictures are taken at f/1.4 or f/2. And all frames were taken in artifical light.

Where is this flaring coming from?

Strangely the flare always seems to be isolated in the same area; however not on every frame. It has happend on multiple rolls - in addition to the samples i'm showing from my latest roll.

There appears to be multiple light sources and I wish to learn how to anticipate these results. I've come up with a number of cracked theories. The most viable is a flaring from an artifical light source; but which one?

other crack theories include:
Is it the SC lens? Do I really need to buy the MC lens instad? Is my lens bad? Lets but another lens (Burp! sorry, gas). Is there a hole in my shutter (this one was given to me from someone else. seems the most impossible)

Thank you.
