Hi,
Could you may be help with this problem:
When I do some metering using my 110 mm Sekor Z lens, changing the shutter speed does affect the prim reading: up, + - down indictor flashes according to the selected shutter speed. However, when I turn the aperture ring, the state of the metering does not change.
The PD prism seems to take the reading from the full lens aperture. Also, the prism is responsive wrt the aperture changes when the Depth-of-Field Preview is depressed at a given aperture value.
I suspect that the lens does not "speak" to the prism with regards to the aperture values.
The lens is fully functional.
I would like to note that this problem seems to be with this lens and not the body or the prism, as changing to my other 90 mm sekor z lens, the prism metering is responsive at all shutter/aperture changes.
Does any body have hints or tips on how to fix this problem?
I tried to clean the lens coupling but without success.
Thanks in advance.
Mourr
