These images were taken in super thick pea-soup fog. Now I can’t swear to this but I do believe the images below would not have been taken as easily without the latest firmware. When I was photographing this scene, the X-T1 locked focus INSTANTLY – when using the 5 x 3 center area.
I am very, very impressed with this firmware when used on moving subjects but this is truly an added benefit to having FW4.0
I can’t wait to see what else Fuji is going to throw at us next!
