Hi everybody, I just got my first Rolleiflex, an MX, 3.5 Xenar. I was testing everything out after just receiving it and I noticed that the shutter blades never fully retract. I attached a couple of pictures I took on the bulb setting at 3.5 to show what I mean. Is this normal and am I just being paranoid? I would think this would cut off the edges of the shot/cause some blockage. Any help would be appreciated!
