Thom Hogan has a post on his website today talking about the shutter alternatives available on Z bodies (at least prior to the Z9). He notes that certain Z mount lenses force the camera to use electronic front curtain shutter (EFCS). One issue with EFCS is that you are limited to shutter speeds of 1/2000th or slower. Thom says that the upcoming 100-400 mm S lens will cause a Z body to default to EFCS and will not allow it to be changed. So the 100-400 mm lens could not be used at shutter speeds faster than 1/2000th. If true (and I have no reason to doubt Thom), that seems a terrible design choice for a lens that many would buy for sports, wildlife and other action. Perhaps it could be changed in camera firmware or lens firmware. And I hope this will not be an issue with the Z9 and the 100-400 mm lens.

[Added 12/1/21: Note Thom has revised the post on Z camera shutter options. Looks like no significant issue here. May be limited to selecting Auto or EFCS as a shutter type. But Auto switches from EFCS to Manual at 1/250th and allows all the shutter speeds the camera is capable of. So not limited to 1/2000th and slower. More discussion below, but wanted to make sure anyone starting to look at this thread is not concerned.]
