It’s been a pretty common thing since the early days of Nikon’s VR and Canon’s IS, that you turn stabilisation off in lenses when using a tripod. As technology has progressed, turning off the stabilisation hasn’t been important. Fuji, though, has long said that IBIS should be turned off in cameras when shooting on a tripod, nothing has really been said about their lenses. At least, not until now.
The folks at Fuji Rumors spotted in the manuals for the Fujinon XF 16-80mm f/4 and Fujinon XF 200mm f/2 lenses that users are specifically advised to keep stabilisation turned on all the time, even when using a tripod.
