“Fujifilm just released new firmware that fixes the following issues:
The phenomenon is fixed that in the MF mode, repeated halfway shutter pressing can shift the focus point under a specific exposure condition.
The phenomenon is fixed that in the AF-S mode, repeated halfway shutter pressing can shift the focus point with SHUTTER AF setting OFF….”
Whenever possible I wait until a number of reports are in from other users on new firmware updates before applying the update to my own cameras. Websites like FujiRumors and their social media channels are invaluable in that regard.
I have held off on applying the version 3.11 firmware update to my X-Pro2 until more user reports are in. So far there have been reports that, post-update, “the EVF is laggy, even in High Performance mode, and the image ‘sticks’ in the screen while shooting. Also the pop-up screen for the hybrid OVF sticks up while the EVF is active, and performance slows considerably.”
Another user has reported slower face detection and focus confirmation beeps even when the lens in not in focus after installing the firmware update on his X-Pro2 and X-T2.
