Subject: Setting aperture -- film SLRs
A quick question, something I am curious about -- I've read a lot here
about the compatibility of older lenses on newer bodies, but what about the
other way?
Specifically, on film bodies without a thumbwheel (MZ-S, ZX-5n, etc), how
do you change the aperture when the lens is set on "A" or the lens does
not have an aperture ring? Is there a way to directly change the aperture
on the body? I assume you can affect aperture indirectly by changing
shutter speed, but can you operate in Av mode?
Are such lenses even usable on older bodies like the MX?
You can use the non aperture ring lenses on cameras that have programmed AE
or shutter preferred AE at apertures other than fully stopped down.
The Super Program/ Program Plus, P3, P5, and most of the PZ/MZ cameras are
able
to use these lenses.
