Yes it's the PLM version so I guess it makes sense this lens works fine

Thanks for the info.
The burst mode did in fact unblock it and it works normally for a period of time.
If I shut off the camera and leave it for 10 min the problem returns but can again be fixed using the burst method.
But I guess this is pretty conclusive that this is the aperture block problem.
Curious that this issue is present only in my 18-135mm lens. The other zoom lens does not exhibit any problems (at least not yet).

I checked out the link but I'm still not sure if it's the aperture block issue.
As per the instructions, Method 1 outcome is exactly as described (in Av mode @ F3.5 the image is dark while @ F22 the image is bright)
Using Method 2, looking into the lens and going into Live View mode I can see the aperture move correctly (which I assume means the solenoid is working)

Wondering if someone can help me determine if my 5 year old Pentax K-70 does in fact have the aperture block failure.
When I use the standard lens that came with it (DA 18-135) the pictures are OK if taken in LV mode but dark when using the viewfinder.
However, when using my other Pentax lens (HD PENTAX DA 55-300mm F4 5.8 ED WR) the images are OK in either mode.
Just looking for confirmation if this is the dreaded "aperture block failure" I've been reading about. Since this is within the camera I would think it would affect either lens.
See sample pics below: dark one using viewfinder and bright one using LV
