got the XC, it's incredible value, probably best value for money lens in Fuji camp.
It's sharp enough from wide open, plenty sharp at f/8. Bokeh ain't bad either.
I'd say - if you want to shoot a lot of pictures in that focal length, maybe go for 55-200 instead, for aperture, even better sharpness and bokeh. But if you shoot at tele focals just from time to time, like me - you can't go wrong with XC50-230, it's so tiny and lightweight. I find the XC to be much better than my Tamron 70-300VC that I got on Nikon mount, and it's less than half the weight, size and price!
I got mine for 140EU brand new, watch ebay and such for people selling brand new ones that came with body or they got it on sale with other lenses.
