Fujifilm GFX100S: Severe Blurring from IBIS, Partial Frame
IBIS should reliably make sharper images. But this page shows that IBIS can cause severe damage to a very large portion of the frame, and in a manner so consistent that it suggests a nasty bug with the IBIS system.
The issue
A very large 1/3 to 1/2 of the right side of the frame (bottom half of the sensor) is extremely blurred for 5 of 11 frames.
I had not come across this phenomenon before. Could it be something other than IBIS? I don’t see what else it could be.
Were it a lens with lens skew, then every frame would have a similar blur issue. Instead, we see that about 5 frames are severely blurred on the right 1/3 to 1/2 of the frame, and 6 frames are not blurred at all.
