and the best IBIS around (stabilsing any lens that is mounted on it)

and shutter shock because of that

You got that wrong. Shutters cause shutter shock. Stabilization systems don't.

no, my friend... IBIS can't handle shutter shock caused by shutter... that's why GH3 does not have it... sensor is one mass w/ body.

If you'd remember earlier discussions between us about this matter, you'd know that there is little in the way of evidence to support this theory of yours.

Does the E-M5 IBIS cause shutter shock? Clearly not. The shutter causes it.\

yes of course - at no point I was stating that IBIS is the source of shock, but it is the reason why shutter shock effect is in place (because Olympus IBIS by design does not make sensor one mass w/ a body + body is light itself)... IBIS can handle low freq hands movements, not shutter shock vibrations... why do you think Olympus included an antishock delay options in its firmware... there is no mirror... there is only shutter and Olympus has to do this because their IBIS was making the effect to pronounced at certain exposure durations

Does the E-M5 IBIS significantly exacerbate the shock caused by the shutter? Not that I know. What evidence for that proposition would you point to?

the mere fact that Olympus was forced to include a special antishock delay in EM5 firmware for users to use is a profound acknowledgment from a manufacturer (and as you perfectly know they don't do this easily).

Does the E-M5 IBIS counteract the shutter shock? Regrettably not.

true, that was the whole point - shutter shock exists because of IBIS... remove IBIS, make a body w/ a proper grip and weight and you have no such pronounced effects @ the same exposure times... that is the price you pay for IBIS

Unfortunately, this makes the E-M5 IBIS close to useless (in my personal experience) with certain lenses at certain shutter speeds.


But IBIS doesn't make things worse than they would otherwise have been

it does, exactly because sensor is not one mass w/ a body
