Originally posted by Kyrsten Stone Hi there,
I have several older lenses and just wanted to check, i think to make the camera meter correctly in aperture priority mode using the old lenses you would press the green button
is this correct?
and do i have to do this before every single picture / do i have to hoold down the green button whilst trying to press the shutter at the same time?
the lenses are auto aperture but manual focus (Pentax A) style lenses.
thanks

A,M,K lens will use center spot light metering
"A" lens set in aperture priority automatically sets shutter speed at what you are pointing at just depress shutter.
"A" lens in M mode adjust your aperture and shutter via your dials
"K" & "M" lens will use center spot light metering
"K" & "M" lens will require set up in your menus to release the shutter when the aperture is set to something other than A, you will also need to use the optical preview feature to get the light meter setting in M mode as over or under and adjust your aperture at the lens and your shutter at the dial
The green button best used with "A" lens in M Mode to get the quick exposure numbers.
