Good afternoon, I recently updated the firmware of my xt2 to version 3.00. I also bought the Fujinon xf 50-140mm f2.8 LM OIS WR lens, and what happens with this lens is the following, I take a photograph, press the button to view, and when I re-shoot the camera can not focus, and the The lens aperture information appears f0, and only returns to focus after turning the camera off and on again. I have two more lenses one 35mm 2f and one 16mm 1.4, and with these two lenses in the machine, it works normally. I went to the store where I bought the lens, and tested with the store owner, a lens of his, like mine (50-140) on my machine, and the problem remained. Then we tested my lens (50-140) on his machine in which he did not have the latest version of the firmware and the machine worked normally without problems. I deduce that the problem here is an incompatibility between version 3.00 of xt2 and lens 50-140.
