I'm not a Fuji X shooter (yet), but I can tell you that I usually don't see point light sources turn into stars until I stop down a little more than f5.6. Next time your shooting in that situation, try stopping down to f11 or so and see what happens.
Thanks, but I have already tried everything between f/5.6 and f/13 and it doesn't help. Sorry, I forgot to mention this in my first post.
Oh well, I'm happy with the Fuji for just about everything else, so I'll just use my Ricoh GR for troublesome light situations.
