I gave you a link to a millisecond clock and explained how to process the data, and you did neither one.

Looks like between 10 and 50ms to me, but you'd actually have to do the experiment right to figure it out.

you are right . im off to work but will shoot it with a faster shutter speed when i get home. 1/100 sec clock will do but will have a look at you 1/1000 later. interesting test though.

It is obvious that the timer does not have very much resolution. One image, for example, is a blend of .62 and .67. Did you not notice that? That means that it sat on 0.62 for .05 seconds, and then jumped to .67.

You have to have both versions of the timer at the same horizontal position in the frame of the camera recording this. Different horizontal lines happen at different times.

If you average dozens of frames.

I've done it many times, and gotten numbers from 25ms to 130ms, depending on conditions and settings.
 
Don't have the slightest idea what this is trying to show. Just look through the viewfinder and pan side to side quickly. There it is and if you say you can't see it, you are not telling the truth. You will never see it with a motionless camera and subject.

your not thinking are you John ;-) the shutter speed of the camera taking the image is 1/25 sec :-) i expected more from you mate.

i can pan shooting a car driving past my house doing 80 klm i dont see what the problem is. a guy posted some images of a motor bike race doing 300 k with no problem. i want to see someone post an image of a aeroplane with trees in the background :-)

just shot some more shots at 1/500sec and got between 0.01 sec and 0.03 man thats fast i even go some 0.00 at 1/500 sec

Yes, pan the camera fast back and forth - and push the camera processing at the same time by setting the camera to AF-C and press the shutter, taking series while the AF is working. Do this is good light and in bad light and with autoexposure.

What exactly is the question being discussed here?

Is it a question is or is there not EVF shutter lag?

Or is the question how to measure it?

Or is it what is the values of the EVF lag for current mirrorless cameras?

There is definitely EVF lag because cameras EVFs have finite refresh rates. I think the Sony say their latest mirrorless have EVF with a fast 240 fps which means the EVF is at least 4.2 milliseconds. I see some recent Fuji mirrorless cameras state a 5 millisecond EVF lag.

So exactly what is the debate of this thread?

Ok - but in this case, the lag in the EVF is also affected by the very low light, if sampling every 1/25. Moreover, many EVF have a power saving mode that cutthe refresh in half, like the Sony. Not sure about the OMD.

Also, if you don't like 25ms˜50ms lag, get a DSLR. Maybe mirroless are not for you. Nothing can beat the speed of light, literally.
 
A nice example of how not to do an EVF timing test.

Things to fix:

1) Need to have a high resolution clock. This one clearly isn't with both .x2 and .x7 being displayed in some frames.

2) Camera display and main screen have to be at the same vertical position in the recording sensor, otherwise there is an unknown delay between the two in the readout rate of the recording sensor. At least mention whether the recording camera was in electronic or mechanical shutter.

when you get sick of mirror lag and missing the shot buy a mirrorless :-)
