You know, Bob, I started this thread and I really feel it has validity. So I tell you what..... you meet me, and anyone else who wants to join, and lets shoot and see .... and I don't mean in your back yard so I have to travel there..... OK?? I got the time and the interest and maybe then you will finally see or maybe I have the only faulty Sony camera.....Maybe it is my old eyes, but I have peered at lots of images that were supped to demonstrate shutter vibration blur.
I just don't see it really.
Shutter vibration blur usually has a directional component to it. Consider that the shutter is not bouncing around in all directions and there is no mirror slap to confuse.
What I DO see from time to time is just old fashioned blur, of the sort that you might see in a lens that is not critically focused. I see more generally soft images than I would expect without a hint of directionality to the blur.
Is it just my eyes or is there something with the focus that needs to be worked out?
