errr.. is this normal for my Oly 35RD

I am trying to figure out if this is a start of
the sticky shutter issue...

at f1.7 at the widest aperture, at 1/30 and above, the aperture is round when i trip the shutter.

at 1/8s, it is a big 5 side hexagon.

at 1/4s it is a medium sized hexagon

at 1/2s it is only 1cm wide hexagon.

somehow, the aperture gets smaller at slower speed.

is this a feature or a bug ?

If it's in Shutter Priority (AE) mode then that sounds right...longer shutter speed means a smaller aperture for correct exposure...
