vibrations from the shutter.

we talk of preventing image blur with tripods, mirror lock-up, and remote shutter release when using long lenses and long exposure times. how much do shutter vibrations fit in this equation??? the shutter opens and closes, so what strides have been made in dampening those vibrations????

Mirrorless cameras.
No mirror is the best stride.
I can hand hold my X100T to 1/30 no problem, 1/15 if I prop against something and get sharp usable images.
There isn't any inherent mirror slap or shutter movement either; the "iris" sort of shutter it has really is an advantage in this regard.
this isn't "art" but I just took it to show what 1/15 looks like hand held.

Well, the new Nikon D810 has a special dampening mechanism on the mirror to help stop vibration from mirror slap. One can also use the new front curtain feature along with mirror up settings to help stop vibration, but of course the subject cannot be moving. I tried this out recently with a very cooperative barred owl. I used the Nikon 300 f/4 lens with the Nikon 1.4TC, the Mup setting, no flash. The first image is the full frame and the second a cropped in view. I also was using the full DX mode of the D810 giving a 15 MP raw file. The other settings were iso 500, f/7.1, 1/25.

Beautiful shots, Nancy.
Do they usually use a single footed stance while resting?

I think I will always suffer from Mirror Slap.
Much better than Wife Slap. :lol:

Thank you Sonny! Yes, if they are relaxing or sleeping they sometimes stand on the one foot.

OK, that's your opinion. ;)

Yes mirror less and electronic shutter is a huge step forward. Beats an awkward solution as found in my D810.

How about almost any leaf shutter camera with a decent shutter release?

I can't imagine that any vibration from the shutter closing could have any effect on the image, but certainly the opening might.
The Luminous Landscape did an interesting comparison test between the Pentax 645n, which lacks MLU and the 645nii which has MLU. http://www.luminous-landscape.com/reviews/cameras/645-mlu.shtml The test involved mounting the Pentax 67 300mm f4 on the tripod supported 645 with the adapter and making exposures with and without MLU. While the whole assemble "shook" noticeably, it seems that the vibration was due to the return of the mirror, and the motorized film advance. The images showed no difference between MLU and non-MLU.
Of course this is valid only for the Pentax 645, YMMV. I use MLU whenever I can if the camera is so enabled. Can't hurt, might help.

A really overrated issue....in all my years I've never had a problem with shutter "vibration" I think it might be more of an "I can't hold my camera steady" issue... :idea:

You are correct - shutter vibrations when coupled with inadequate tripod/head are the principal cause of blurred images when shot between 1/10 and 1/160 sec.
Mirrorless cameras are just as susceptible - read the various posts about the Sony A7R and others.

Unless your camera has an electronic front curtain, shutter movement can affect an image.
The best prevention is to get the right tripod. Forget about shutter delay, remote shutter release, mirror lock up - etc etc etc. It's clearly not the mirror. No substitute for a solid platform. Period.
