I am new to the gfx system, and I rarely shoot slow shutter speed images. I shoot mostly with the sony A1, so electronic shutter all the time.
I am taking a weeklong trip exploring shooting waterfalls/streams with the gfx 100sii. Tripod based. Remote trigger.
I really do not like the distortion of rolling shutter. I am looking for max sharpness without shutter shock- large prints 40"++.
My "plan" is to use ES for shutter speed longer than 1 second. My "understanding" is that at longer shutter speeds the slow readout speed is such a small percentage of the exposure that rolling shutter will not be an issue- even with moving water??
Shutter speed shorter than 1 sec I plan on using efcs.
Yes, I will evaluate while shooting, but thought I should ask those with experience if this approach is a decent way to start.
Thanks for any help and guidance.
I don’t personally see a logical reason that would necessitate using the electronic shutter for long exposures over mechanical. If you’re worried about shutter shock, you’re already mitigating that by using a remote trigger, and in general, shutter shock is more of a concern of a bygone era.
In general, electronic shutter will reduce your possible dynamic range, which is the entire point of shooting one of these cameras.
RoamingScott,
Thanks- that is exactly the guidance I was looking for. I had not considered dynamic range reduction- which is, as you point out, one of the reasons I am trying out this system.
thanks again

You might also test for yourself the impact of leaving IBIS on while it's on the tripod, vs turning it off. People have very strong opinions about this one, so seeing for yourself is the better plan.
I personally leave my IBIS on during tripod work, but others swear by disabling it for sharper photos. For long exposure smooth water shots, you'd probably not tell much of a difference
Ah yes, the IBIS question.
I will be traveling with a small laptop- so image evaluation will be limited.
Shooting on a tripod in the sand/water- with other systems I usually leave VR or IBIS on.
I will try both on and off.
Thanks again

I have experienced shutter shock with the 100S (same sensor, different IBIS I think) but only in conditions where shutter shock is more likely, a long lens, slow-ish shutter, and a travel tripod. If you are 100mm or shorter, I don't think its an issue when using MS. For longer focals, EFCS has worked for me. Or just leave it on EFCS all the time, I don't think there is a DR penalty, certainly not a visible one.
Side note - a separate issue but you might want to run the Pixel Mapping utility to map out any hot pixels before your trip. Low light and slow shutters are prime to show off your dead pixels.
Per Kasson’s review, there is no dynamic range penalty to use Electric shutter for GFX100II. So if your shutter speed slower than 1/3s in 16 bit, or 1/8s in 14 bit, e shutter is perfectly fine. For landscape, if there is on wind or moving stuff, feel free to use e shutter.
For artificial light, and exposure time shorter than 1/3s for 16bit or 1/8 in 14bit, be ware of flickering.
In general, I will use E shutter whenever condition allow for GFX.
Zhangye, thanks for the explanation. I am testing the gfx system for a couple weeks and want to give it a good shot. All the above makes sense- thanks again
