Hi Chris,
Yes the shots were over exposed by several stops. Piers suggested that it
may be that the aperture linkage is adrift. I'll check that out as soon as
I finish the film that's in it at the weekend.
However I decided to conduct a small experiment last night comparing
readings from different lenses to see if that 'shed any light on the
problem' (sorry, awful pun ;-)). The problem has been mainly when I have
been using my Tamron 135mm f2.8 lens (I know I'm inviting a lot of "serves
you right for using 3rd party lenses" etc). I took a reading (all wide
open BTW) from a light source using a 50mm 1.4 Zuiko (about 1/500 sec) and
then compared the reading from the same light source using the Tamron. The
resulting reading was 1/8 sec, quite a difference!! Subsequent readings
from a couple of other lenses concurred with the 1/500 sec measurement.
Now the view to the naked eye is considerably darker when using the Tamron,
even wide open, but that's a bigger difference than might be expected is it
not???
Now I'm even more confused.
Jason.
