Re: is my shutter failing? or was it my lenses iris"?"

Mechanical shutter of G7, like all MILCs of Panasonic (indeed should be all mirrorless I guessed), is CLOSE --> OPEN for an exposure.

It is  OPEN in default. So, you can unmount the lens, watch the shutter when taking a shot. Under normal operation the shutter should move smoothly. Try slow shutter like 1/2" and fast like 1/1000" to see the difference. If the shutter has problem, you can see it easily. It can eliminate a faulty m-shutter, or a stuck shutter.

However it will not guarantee would the shutter speed be exactly made.

I suppose G7 should support electronic shutter, would it has similar issue? If no, might be a lens issue.
