Hi,
I've just pulled my RMC Tokina 80-200 1:4.5 out of storage and the aperture
stickiness seems to have worsened markedly. The aperture can be set up to
f22, but if I set it to e.g. f4.5 won't snap back - I actually have to
unmount the lens and push the metal tag back home to open the aperture.
Does anyone know how to dismantle one of these lenses as far as being able
to access and clean the aperture blades? FWICT these lenses seem to sell
second-hand for around £80 and were sold from 1979-1982. That's assuming what
I've found on Google is accurate.
I can see three screws on the outer section of the mount, plus three more
black screws on the black inner section around the metal tags used for the
aperture. There's also one screw visible on the outer section of the lens,
above the aperture ring.
Ordinarily I'd just buy a new lens, but I'm off on holiday in a few days
and all the local camera shops I know of have long since sold off their
remaining stocks of second-hand OM lenses. That and I haven't got the money
for a new lens, and this is my only zoom lens :(
Thanks.
