Double Exposure/secondary shutter

[thelaurels]

I've a 501cm and 80mm & 180mm lenses. I've recently noticed some double exposures on slides.

After some investigation I notice that when I set the secondary shutter, the lens is not closing the shutter before the blinds open. I.e. if I look through the secondary shutter and lock up the mirror, I see daylight before the shutter closes. This has been exacerbated in the cold weather and does not happen indoors at room tempratures.

It is most frequent on the 180 lens, but I have noticed it a couple of times on the 80mm.

Has anyone expericended this before and what is the remedy, should the camera be serviced or the lenses?

Camera and lenses are circa 7 years old and have had light use mostly on holidays.

Thoughts appreciated, thanks.

It seems as if the shutters of lenses are closing to slowly.
Could also be the timing of the camera body is not correct.

I would recommend to have both lenses and the body checked for any faults.
A CLA for equipment this age even though it has seen only moderate used is good practise.

Service for Hasselblad V series is advisable every three to five years depending on how intensively the equipment is used.

Sounds like the shutterblades have oil/grease residue on them. Like Paul says, have them serviced.
