Thatís what I think too, but there are always those who donít agree.
I'm not saying "I'm right, you're wrong". I'm saying, I have a position for which I have evidence, and in the absence of better evidence, I see no reason to believe the contrary.

I've read dozens of speculative "I've never seen it, but on the basis of some highly imaginative hypothetical mechanism for which there is no actual evidence, I believe it" type of reports, but not a single one bringing hard evidence to the table.

Design an experiment that excludes all the extraneous effects, make some measurements, and present the evidence for peer review.

Then let's talk again.

I also think the bottom line is that you should not have any shake while on a tripod!
Leaving aside all the speculation, this is incorrect.

Even on the tripod, if you release the shutter in one of the non-delayed modes, by pressing the shutter release button with your finger, the shake so induced (even if you're careful) is very real, and easily seen in the results.

My comment wasnít meant as a stab at you, or anyone else for that matter. I only meant that there is no ďabsolute truthĒ out there in which everyone agrees.

I can however contribute with a small observation regarding shooting before SR is ready.
I start the camera without a lens mounted, 3 seconds exposure, 300mm focal length and holding the camera by hand. Then I observe how the sensor moves depending on how fast I am on the shutter.
It looks to me as if SR isnít ready the sensor doesnít move at all, which makes sense. So if one is to fast on the shutter the result is the same as if SR was off, not worse.
