He is no fool who gives what he cannot keep..to gain that which he cannot lose. Jim Elliot, 1949
Regarding vibrations and big shutters; big shutters have big mass as do the lenses they carry so inertia reduces any vibrations from the much lighter weight shutter blades and rotating mechanisms. I've used some huge shutters and never seen a vibration problem from any of them.
Regarding optical matters; this shutter would behave like a glass filter in front of the lens. It will have some effect on the rear focus point. If there is any diffusion in the crystal structure, that would degrade the image. How much? We must test!
Regarding the fun factor; I envision some fun stuff. For example, if it is an lcd array, it could be programmed to produce an aperture of any shape or size. Think of the bokeh possibilities! It could also screw things up if a pattern in the subject interfered with the lcd pattern.
What are the exact optical characteristics of the LCD in transparent mode, e.g. refractive index, color fidelity, etc?
Unlike a real shutter, an LCD shutter is in the path of the image-forming light, and will introduce aberrations and distortion.
Isn't the front surface a polariser as well?
Regardless of any real or perceived problems with it, I think it's an interesting idea worthy of some experimentation.
Forgive my ms-understandings, this not directed to anyone personally.
But, I believe the root word and action is movement, period.
Counteracting, suppression, whatever you call it, it's still movement of some kind.
Thus my continued use of sand bags w/ long telephotos on smaller formats.
Even though sometimes a minimal improvement in sharpness, but is easily seen in any test I've tried.
I used the phrase "unlike a real shutter" because an LCD shutter cannot
match the performance of same in either transparency or opacity.
While it may be a functional analog, it is not a functional substitute.
I think the real question is
How many megapix will this be?
Joking aside, this sounds rad. I'd love to see one and put it to some funky uses.
