This video from the Fuji Guys may help you decide on which lens you might want to upgrade to be it a nice prime of a higher specced zoom.
Theres no better time than now to grab a new Fuji product , with some very nice rebates you can get into a new Fuji X series camera.
My pick for the Xmas stocking is the XT-10 coupled with the excellent XF 18-55 mm f2.8-4.0 lens. A really nice starting combo. Grab yourself the very nice XC 50-230 mm lens for a good all-purpose tele lens and you have pretty much all your shooting needs covered.
