This time around the Fujifilm firmware buzz really hit the roof, with claims of an all new autofocus system that would practically give existing X-T1 owners a brand new camera. Bold claims indeed. Claims not only made by those saying they had gotten hold of rogue and secret beta versions of the firmware, but also claims made by Fujifilm themselves in their marketing teasers. So, since Fujfilm decided to play the cocky marketing game, I set out to prove them wrong. I mean, it can’t be that good, can it?! Again I mean, because firmware 3.0 was a pretty fab upgrade. So I begged my friends at Fujifilm Nordic for an early version, so I could weave my secret web and reveal to the world what v4.0 was really about. So with this devious plan in mind, and an evil laughter soon to come, I jumped in the front seat of a car, and we head out for the highway. Having set the camera to the new Zone focus mode in the menu, continuous focus on the front switch, and Continous High as my drive mode, I told the driver to hit his continous high with the maximum allowed speed of 80 km/h. But that was only half of my devious plan. Because what lens did I choose for this test?! Well one of the oldest lenses of course, a lens that many people claim to be both slow and sluggish at AF. The XF35mm. And of course, I’d shoot it at maximum aperture, f/1.4, through a windshield that seemed to suffer from some bad programming. It wasn’t bug-free… In other words; The Impossible Test! …..
