I’m mostly loving the F ( this is my first X100). I have the X-T2 but Im pushing the boundaries with the F to improve my photography. I have noticed ( mostly an hour or two before dusk ) that if I have the ND filter setting on I get a ‘haze’ in the image. It was so pronounced that I actually wondered if I had some condensation on the glass ( I didn’t ). Has anyone else had this? A little frustrated.
