This second version of the WCL and TCL are optically identical to the first generation. What changes, though, is that inside the WCL and TCL ver.2, there is a little magnet, placed in different positions. These magnets allow the Fujiiflm X100F to automatically recognize if the WCL or TCL is attached, since they are designed to match one of to two magnets placed inside the 23mm lens of the X100F.
That’s handy :)
In fact, FR-reader Haoyuan came up with a “hack”, that makes the old WCL/TCL recognizable by the X100F. You just need 2mm x 1mm magnets, an electrical tape (or a Blu-Tack Adhesive), Plastic Tweezers, Sharpies, and a permanent adhesive (optional). And how exactly does it work? Well, jump over at haoyuanren to find out more :)
Another one Hacked it too, using the magnet that comes with the X100F box and a gaffertape. You can’t do it cheaper :)
