Yes, I was talking about Silent mode. I added a footnote to my
Post
Maybe im not seeing shutter shock at all. Maybe as other have pointed out it might just be the IBIS causing this, as ive not had a camera with this before so im guessing.
I had a set of shots i took of a person walking, and although it was shot at 1/160 i could see a definite double image, rather than just a blur. I was tracking by moving the camera, but ive never seen this effect in my shots before.
All my poor shots were with mechanical shutter. I hadn’t ventured in to the EFCS and ES at that point. With testing i have noticed all the ES shots seem spot on unless i make a mistake, and i have tested EFCS and also got decent shots, so maybe its just down to me needing to get to grips with the camera.
I’ll test it out over the weekend, now armed with more knowledge, and if im still not happy I’ll send it back on Monday. I must admit i am feeling a bit more confident in it after these discussions. At least i know the camera isnt necessarily malfunctioning.

A double image seems to suggest the IS might be jumping very quickly from one position to another. Human shake is usually in squiggles.

EFCS is a mechanical shutter mode, as the second closing curtain is mechanical, but if you take isolated shots or in a very slow burst, it won't cause any shock during exposure. If the bursting gets fast, though, the closing curtain may still have some shock by the time the next exposure starts.

Nobody's using MSDOS or its filesystems anymore, so I don't know why the cameras don't just have longer names with the time in them. That would only give overlap if you changed the time on the camera back to an earlier time, to come off daylight savings time or when travelling, but if an option to use universal time were there, that would never be an issue.

I thought the Canon in camera OS was based on a UNIX core.perhaps this is the reason....?

Or IBIS and IS are contracting each other as it smooths out? I get that ghosting from time to time with my R5.

Just to make sure I understand, you’re getting double images at 1/160 with an 18-135mm lens?

Something is definitely wrong.

Have you used the same lens recently on a different camera body? Doesn’t have to be mirrorless. This just sounds to me like a lens problem.

Yes, thats correct, but it was only that one set of images and i was panning. Ive used the lens daily on my M50 with no issues at all.

Thanks, I’ll bare that in mind in future. I was in H+ mode for those shots and i did think it was IS as it looked too defined to be normal motion blur.
Might have just been a one off situation. Im certaily staying away from H+ for now, and will trey and use EFCS rather than MS
Ive shot almost 800 shots so far, and it was just that one set of shots that had this issue, others have been soft but sometimes it’s been camera shake. I must say im very impressed with the battery life. This is all on the first charge.

It's hard to keep track of all the factors, but any ghosting that looks like two sharp images misaligned but blended together had a registration change that was very fast, occurring only once in a small fraction of the exposure time, and not likely to be from an actual lens or camera motion, which would be slower, with squiggles.

I sometimes got this effect with the Tamzoka, normally in the highlight in a bird's eye. This happened even with IS off on a support, presumably mirror slap as was vertically displaced.

Sounds like something similar, but surprised the shutter curtain could cause it with shorter lenses if the photographer's stance was well braced.

If you scroll down to the last 20% of this page there is a video that shows how this works. It shows how both IBIS and IS do not sync (move together) but work independently of each other. You see where errors can occur especially with fast targets ad tracking.

Also shows how IS mode 3 can be beneficial for erratic subjects. All of the these things are happening in milliseconds. Pretty astounding actually but I'd still like to be able to shut IBIS off and just use IS. It will even get better as processing speeds and algorithms improve.

It's a little different than my old Minolta X700. I could never find the LCD

Yeah, I think that was before they started doing IBIS....

Oh yeah. I took it as "we don't need no stinkin IBIS" while he is wondering how the R&D department is coming along with IBIS.

…but we wont let you use it without the less effective one ߘ

Wonderful images!

There maybe a few scenarios where the R series image stabilization is not highly effective, but I have not encountered them. For sure, it opens up many new opportunities to hand hold shots that could not be hand held any other way.

Very True
