I have no ideia if that is the reason, but someone sugested that the EM5 and EP5 shutters just go to 1/4000 instead of 1/8000, and the extra acceleration was reponsible for more SS turning it visible in the images. Really can't confirm that.

E-P5 shutter goes to 1/8000. Probably the same mechanism as the E-M1.

You are right of course, i made confusion with the EPL5.

The fact that the E-P5 and the E-M1 go to 1/8000 rather than 1/4000 is of no importance per se. The higher max speed might theoretically be accomplished by using a more narrow slit.

What might matter, however, is that the E-P5 and E-M1 both have a higher flash sync speed than earlier Oly bodies. This in turn implies that the shutter blades move at higher speed, thereby involving stronger forces (if the blades are equally heavy), which might increase the likelihood of significant blur due to shutter shock.

Note, however, that shutter shock is by no means a phenomenon confined to these two bodies. Prior generations of bodies are clearly affected as well.

Bla, bla, bla. Techno babble with no substance.

If one of us is babbling, it is not me.

Make up your mind. Is SS caused by stronger shutter blade forces? or you are just as confused as anyone else?

Unlike you, I am not confused. What I am saying is that stronger shutter blade forces will cause a stronger shock, everything else equal. This follows directly from the laws of physics.

I own both cameras, and I find that the vibration transmitted to the body is less than on previous Pens, or E-M5.

And you found that exactly how? Here is an example of the kind of test required to show something like that:

Did you perform such a test?

This is even more so when the SSL is activated.

What you do when enabling the SSL (short shutter lag) is to relocate shutter "cocking" from the beginning to the end of the shutter sequence. To the extent that this "cocking" action is responsible for part of the blur, you will eliminate that part by enabling SSL.
