Hello, I just bought a G-Claron 305/9 at a reasonable price. However, I am realising now that 1s and 1/2s speeds seem to hang especially first time after not being used. After firing it 4-5 times, especially at the higher speeds, they then run through normally.

Is there an inexpensive fix for this or should I return the lens? I assume it has to do with the age of the shutter and lubrication. Should I work it out a bit so it will go away?
