The selection of lenses offered by Fujifilm for its X series cameras is slowly expanding. http://www.fujifilm.eu/eu/products/digital-cameras/fujinon-x-mount-lenses/ So far I've only used the basic 18-55mm lens on my XE-1, which is a lovely versatile piece of glass but wonder if I should consider getting another. My particular beef is that the autofocus is a bit sluggish and I'm missing a lot of spontaneous people shots - it has been flagged as a general shortcoming of the camera, but maybe a fast prime could improve matters? That said, I'm starting this thread to find out what you all think about the X series lenses in general. Now they've been around for a couple of years, are there any favourites emerging?
