Yeah 40fps of jelly motion shots (more than 33ms of readout time), thanks i'd pass.
It's not even possible to do 40 fps with only 33ms.
The readout rate at 14 bits is 26 fps therefore 38.3 ms however in burst the camera drops to 12 bits at it can read 60 fps at that bit depth making it 16.33ms readout
This is not a bad value I have used MFT camera with 60 fps in electronic shutter and unless you are panning like crazy the results are normally acceptable
Clearly not in the same category of the Sony A1 that has 5ms readout or the Nikon Z8/9 but more than enough for many situations
But you have to consider, 60 fps is for 16:10 aspect ratio. For 3:2, it's something between 40-50 what it theoretically can offer. According to Panasonic it's about 20 ms for 12bit and 36ms for 14bit. That's a little worse than a Canon R5 (ca. 16.4 ms for 12bit) and about the same as a Canon R6 (ca. 19.6 ms for 12bit). But better than a S5II (ca. 26.3 ms for 12bit)and much better than an Sony A7RV (ca. 50 ms for 12bit).
I think 20ms is usable even for many moving subjects, but of course it's to slow for very fast subjects.
