I'm fairly surprised by the lack of more visible shake all round. It looks as if making three or four exposures with the shutter speed set slightly above the focal length rule (1/80th-1/100th here at 70mm) will in my case produce at least one clean result.

There shouldn't be any clean results if your alleged shutter shake is real. How do you explain a clean result with shutter shake? The earth moved just the right amount to counterbalance the camera shutter at the exact moment maybe?

If you have any experience of cameras in general - I have in all formats from subminiature to 10 x 8 including some of the worst shutter-mirror shake offenders ever made, like the Bronica C - you'll know that hand-held results always vary, and photographers for the last 130 years of instantaneous exposures have often taken several shots 'to be sure that one is sharp'. Of course, you can't be sure that one will be sharp. You can be unlucky or inexperienced and end up with every shot you take at 1/100th (or whatever) lacking sharpness. If you are aiming for very high standards, you may detect shake at faster speeds too.

This has been one of the great benefits of stabilisation. It hasn't just made hand-held 1/30th, 1/15th and so on possible - it's radically improved the outcome of exposures like 1/125th, 1/250th and even 1/500th. When the Dynax 7D appeared, I was able to interview the designers at photokina, and one of my questions was whether the AS was disabled at fast shutter speeds like 1/1000th. The answer was no - it worked all the way to 1/4000th, and it would improve many shots taken at faster speeds.

If I couldn't get clean results hand-held I would never have been able to make a living. In 35 years of film shooting I never had stabilisation and I'm sure I took more hand-held pictures than tripod shots.

No-one is using the term 'shutter shake' because it isn't - as with mirror action, it's a shock, a transmitted vibration. This can be absorbed, reflected, converted to sound (in fact a loud sound often means less energy is converted to movement - like the old Miranda Sensorex mirrors which fire with a hell of a clack, but you hardly feel the action). A mirror can be damped or braked, even the most basic thing like a foam pad, or the small spring-loaded baffle found in some Minolta models. This is maybe not an option for the shutter curtain.

It's not an 'alleged' shutter shock, it happens and you only need to own and use the camera to realise that. However it may be an 'alleged' range of outcomes, with some suggesting it's mission critical and others suggesting it really doesn'ty matter. Both may be right - one may be a professional wanting the 36 megapixel sensor for pure pixel level resolution on technical work, one may be a keen owner with less than 20/20 vision viewing the images on a Retina display.

Possibly when REAL SS occurs, it is a much-amplified effect caused by acoustical resonance. That should have been tuned out by thecamera maker on design and if it wasn't, then that is just sloppy work. Sony cameras have not experienced shutter shock since Sony put in a remedy that works, after the original NEX3 and NEX5 cameras.
