What is the point of denying the existence of possible small blur due to shutter vibrations at certain shutterspeeds?

I'm curious to know your motivations?

I can answer that, if not for all, then for many of them. Because they haven't had any other choice. I have tested my GX7 and it is a bit sharper with E shutter on. Do i care that my shots are a smidge softer when choose to use M shutter? Hell no, because i have an alternative that will fix it and i rarely have to use M shutter. Olympus users don't have that option, and it sucks to have to admit you are stuck with a flaw. Some are more open minded and those are the ones praising the new FW addition. It's no different than the guy who claims his 6 year old camera has noise performance that's just as good as the new gear. People tend to discredit the flaws that threaten the value of their investment.

And another question : why do you think Olmypus did include the 0s antischock option in E-M1s FW 1.3?

Another easy answer. BC shutter shock is real.

"Run to the light, Carol Anne. Run as fast as you can!"

Olympus has already a very effective feature on the E-P5 and E -M1, called short shutter lag. Shutter shock may be real, but definitely suppressed when this feature is activated. I have ran a test with my E-P5 in the range of 1/80 to 1/400 in 1/3 increments, and all the images are pin sharp.

The 1/8 s (or longer) anti-shock feature available on all Oly bodies is but a partial and circumstantial help. It eliminates the shock due to the first phase of shutter action (shutter closing to prepare the sensor for exposure) but not the shocks due to subsequent phases.

When I test my E-M1 with anti shock set to 0, the sound and vibration levels are no different from when the short shutter lag is enabled. Makes me wonder.

This is because the mechanical shutter moves through all phases as it usually would even with "zero-second" anti-shock enabled, presumably because there is no way to program the shutter so as to skip a phase.

The difference is that with "zero-second" (actually 1/40 s) anti-shock, the exposure is not initiated when the first mechanical curtain opens, as would usually be the case. Instead, after a delay of approximately 1/40 s (25 ms), the sensor is reset and exposure is initiated electronically. This eliminates the shock due to the first two phases of mechanical shutter action (shutter closing to prepare the sensor for exposure and shutter opening for exposure) as well as the shocks due to the mechanical shutter being "cocked" (prepared for action). See the post to which I link below and subsequent posts in the subthread it initiates for details:
