I've been looking on eBay for a used Focus Handwheel in good condition and came across an auction for a pile of stuff including and X3 and a Focus Handwheel.  This individual clearly has teh X3 mounted on the X5 adapter.  So this begs the question... can the X3 be used with the Focus Handwheel?  Everything I though I knew says no.  Comments invited...

Sorry Sir, the Focus Handwheel is not compatible with X3, thanks for understanding.
