R5 - 1st curtain electronic OR mechanical shutter?

Got my R5 a few days ago and I really love the camera. Could've been slightly bigger though, the buttons are a bit small, but I'll get used to it.

Out of the box, the camera was set to use 1st curtain electronic shutter. I changed it to mechanical, mostly because it felt familiar from my DSLR.

Which type of shutter is best to use, and in what situations? I know the drawbacks of the fully electronic shutter, but what about the 1st curtain electronic? Are there any advantages/drawbacks compared to the mechanical shutter?

It would depend to what extent the fully mechanical shutter causes any kind of shutter shock.  On my Nikon Z6 there is an auto setting, that will use EFCS or Mechanical depending on shutter speed.  I thought anything below 1/200 would be EFCS and anything faster than that would be mechanical.

That threshold is probably different on the R5, but the R5 doesn't appear to have an auto setting anyway.  Sometimes EFCS can cause weird background blurring issues at wide open apertures.

Ok, thanks for making this clear to me.

I think I will use the mechanical shutter most of the time then.

Shutter lag is also higher with mechanical shutter, off the top of my head, 80ms with mechanical, 50ms with first curtain.

You also get 1/250 flash sync with first curtain vs 1/200 for mechanical.

My rule of thumb is to use EFCS for slow shutter speeds. It will help with shutter shock.

Seems as Canon really needs to give an auto mode by FW update.

Yes I'd love to see that.  Nikon has it, should be easy enough to implement for Canon.

Speaking about risk of shock, the R5 has a so soft shutter compared to DSLR and even the R.
