Lubrication on aperture blades?
In reply to Anders Lundgren, Jul 31, 2006

Hi,

The lens is wide open with every shot I take, even if I turn the
aperture ring on the lens to other apertures like f32.

Sticky oil on aperture blades preventing them from closing? Bjørn Rørslett writes:

"The f/2.8 design is extremely prone to getting lubrication onto its aperture blades to make the aperture stick unexpectedly when shooting."

There have been threads here how to clean the blades.

I have purchased a used 55/2.8 myself but fortunately my copy works well so far.
