And generally, most of the demonstration of SS i see here are within these parameters (believing they are well done).

If i have a (for me) pin sharp image at 1/320 with 40mm i expect also at 1/250 or 1/200.

Not sure I follow you here. With my E-M5, I don't expect to see much blur due to shutter shock at 1/320 whereas I do expect to see at least a little bit at 1/200 if the FL is sufficiently long, and even more if I go down to 1/100 or 1/125.

I find that with 40mm long (as i said) i should have almost undistinguishable images from 1/200 to 1/320. Of course if i have a 150mm i expect differences.

What I had difficulties following was only your inference from shots at 1/320 to shots at 1/250 or 1/200. If you have actually verified that you get perfectly sharp results at all three shutter speeds, then everything is of course just fine. However, it is certainly possible as well as likely that the amount of blur due to SS increases as you go from 1/320 to 1/200 and 40 mm is certainly not an FL where significant blur due to SS is inconceivable.

My experience before firm 1.3 was: from 1/60 to 1/250 = SS, then at 1/320 no more SS (or if there was it was just a little bit and rarely)

What for me was revealling that something was not right was the sudden appearance of SS in the transition from 1/320 to 1/250 with 40mm, i don't find that normal.

After the firm 1.3 with AS-0s i did a series of hand holding images from 1/250 to 1/15 (40mm) pin sharp from 1/250 to 1/60 and just at 1/30 and 1/15 i can see some (small) loss.

If my problem was just for example at 1/125 and 40mm, sure i could wonder if it was me or the camera, but at 1/250 and 40mm, no chance, my hands don't become useless because of 1/3 stop in that relatively hight speads. Now, with the firm 1.3 i get what i consistently was getting in previous years with Olympus.

Good explanation! I now fully understand as well as agree with your reasoning. Without access to either an electronic shutter (as on recent Pany bodies) or an AS-0 option (as on the E-M1), the process of testing for shutter shock is not all that simple and you have to consider things like those you took into account (exactly what shutter speed and what FL we are dealing with and what would one would normally expect on those grounds).

I went through the same exercise with the E-M5 about one and a half years ago, when the discussion about shutter shock was just starting to gain widespread attention on the forum and far less was known than today. With time, I have found that the critical juncture with the E-M5 is between 1/250, where there isn't much of a shock to speak of, and 1/200 where you start seeing it. On the E-M1, it seems that this juncture is slightly higher (between 1/320 and 1/250), which I would guess is due to the higher flash synch speed and its consequences for the way the shutter blades move.
