Fujifilm XF23mm f/2 R WR review: Autofocus
Unlike its big brother that is known for making some pesky whirring noises as it goes about its business of focusing, this newer lens is much quieter. Not only is it quieter, it’s faster too. The inner-focus AF system uses a stepping motor to drive the focusing elements and when it’s combined with the phase detection AF system of Fujifilm X-Pro2, X-T2 or X-T20, the lens can acquire focus in as fast as 0.05 seconds. When we tested the lens with an X-T2 and X-T20 and then switched back to using the 23mm f/1.4 XF R, there was no question that this newer lens is the faster of the two.
The Fujinon 23mm f/2 R WR XF focuses faster and quieter than the Fujinon 23mm f/1.4 XF R
