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.

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.

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.

What you need to do to test this is first find a reproducible set of circumstances that do show shutter shock with Release Lag-Time set to Normal. Then set Release Lag-Time to Short and repeat the test. If the first set of images show more blur than the second, you will have shown something. If that is actually what you did with the E-P5, great!

I never experienced SS, so the test was to confirm that my camera was giving me good results. I only shot with SSL enabled ( which is my default setting)

My humble test

To me, those images don't look very sharp, although the 1/400 sec looks sharpest even though it as at Iso 3200. The lack of sharpness may be the box printing itself. Or shutter shock. Or something else.

If there is a known issue with this lens, I would suggest that you repeat the test on the E-M1 with and without 0 sec shutter lag. If you use a target with very fine lines (finer than the letters on your cereal boxes), it is easier to see any blur when present. You tend to see a double line rather than a soft edge. Also, compare it to the E-P5. Both 16mp sensors should give similar results. If 0 sec shutter lag improves your image sharpness on the E-M1, I would suggest that it demonstrates shutter shock.

I would be interested to hear your conclusions.

I did this test when I first heard that Release Lag-Time set to Short improved shutter shock but I found no improvement in the circumstances that I tested(E-M1 + 45-175 @ 175mm, 6m focus distance, shutter 1/160).

Just taking a series of shots and saying that they are sharp doesn't show anything.

I tested it with the 45/1.8, which was being touted as the culprit. Either my camera or my technique makes a difference, i don't know. But it works for me.
