Hi all, I am new here.
Just got a second-hand 645N with FA45mm-85mm F4.5. However, when I tried using the aperture priority mode, no matter what f-number the aperture ring is set to, the viewfinder consistently shows only F4.5 and stays the same. The metered shutter speed also shows that based on F4.5
I read the manual of 645N which states: "The approximate aperture indication appears in the viewfinder. It may not the same indication as you select the lens aperture ring especially when the A645 150mm F3.5 or A645 45-85mm zoom F4.5 is attached "
Does it mean that
1. Aperture priority for this lens and camera is not possible?
2. Camera does not read the current aperture number?
PS. I tried dry firing in shutter speed priority with aperture ring set to 'A', it works fine, the aperture changes automatically with different lighting condition.
Helppp pls!
