Quite a good explanation of shutter shock here

That subject had been done to death in some forums, can`t say I`ve ever experienced it with mirrorless but I very rarely ever use a tripod.

Very interesting article, CB.

Yes, I too have not experienced it - possibly for the same reason.

Don't let a minor fact like that stop you from being an expert on the subject CB Tongue

Well you don't, so why should I? Tongue

It doesn't just happen with tripod. I know that the GX8 has been identified as being perhaps a worse culprit than its predecessor [although I have to say having used both, I find it a significantly better camera overall].

I hadn't noticed it at all until the other night, but I do shoot a lot of the time out and about with the electronic shutter, which completely eliminates the problem. Obviously the situations to avoid this are when shooting moving subjects* and shooting with flash**. It was the latter I noticed the other night - not on all captures by any means [in fact relatively few], but enough to disappoint with the odd ruined shot which might otherwise have been a stand-out. Flash sync speeds are typically in the range where shutter shock may come into play.



*the 'jello effect' happens because the sensor reads sequentially from top to bottom - so by the time the readout gets to the bottom of the sensor the subject has moved on slightly, giving that weird angled stepping.

**flash won't work in ES/silent mode, because again the sync can't be made with a sequential read of the sensor.

Interesting. I had the GX8 but quickly got rid of it... not (knowingly) for shutter shock reasons but I was just not 100% happy with results but mainly because it didn't feel quite right - for me, anyway.

I put the sub-par results down to my own ineptitude - I have always been a bit dismissive of shutter shock.

Probably wasn't shutter shock. Blush

In this particular case it does look like shutter shock - it's in the right range and the later shots I did in silent mode, usually at slower shutter speeds were all pretty sharp [maybe the couple of glasses of wine I had relaxed me!] It was outdoors but a warm evening - I did a few staged shots with the thesps in the gardens before the perfomance and then a good few of the performance itself. Obviously not flash [or shutter noise!] with the latter and the light did start to dip. I do tend to shoot auto ISO, so noise is there in some shots [although looking at them on my iPad Pro at reasonably high resolutions it's not over-obvious even at quite high sensitivities], but the only blur I was getting was as people departed the stage!

But as I say it wasn't something that was happening all the time, so it doesn't seem to be catastrophic or all that predictable as to when it's going to happen. I do tend to duplicate shots with flash, but time being tight there were a good few one-offs with a small number of disappointing results.

EDIT:

I'm doing down the GX8. It was actually my EM1 that exhibited that problem - all the shots I took flash-synced with the GX8 are tack-sharp. Ironically I was shooting with the Oly 17mm on that, while I had the Panasonic 35-100 f2.8 on the Olympus body*. In hindsight perhaps there was some weird conflict going on between the Oly's IBIS and the OIS of the lens? The IBIS in that camera is effective down to crazy-slow shutter speeds in normal circumstances.

[*Just the way it worked out as I switched lenses, maybe I should think more about matching marques in future!]
