I have recently acquired this lens and, with much enthusiasm, have started testing it.
In testing it I have realised that there may be an issue with the lens.
The lens is snapped on to my K30 and does so as you would expect. However, when you reposition the aperture ring, the iris remains open - so no variable aperture.
When the lens is of the camera I can easily manipulate the aperture blades without a problem although I can see how, when mounted, the blades would not operate.
Is this a known issue and if so how do I rectify? Help in other words
EDIT
This issue extends to all my K and M lenses (shock) on both my K30 and K01 - I do not understand???
Thanks in advance.
Mark
EDIT EDIT
OK I put the camera in bulb setting and did a selfy ...... wha la the aperture closes to the stopped position on shutter activation. Cool didn't realise this.
I think I am sorted but help/ comment on the topic is still requested ....
