When I was asked for my opinions on version 4 of the X-T1 firmware I was a little scared and excited in equal measure. Excited because the opportunity to shoot in a more dynamic style is quite appealing. Scary because relearning shooting procedures is never easy. I’ve never been one to shy away from innovation and I’m certainly not a luddite when it comes to tech so I jumped at the chance. Here are my findings. I decided to do a side by side comparison in each of my test situations and write up my findings. Writing up experiments and drawing upon the exif data really helps my learning process. I started with two X-T1 bodies running FW 3.11. I set all the parameters on both cameras to be identical and then did an upgrade to X-T1 firmware v4 on the black body only. I found that firmware V4 affects many more elements than I had expected and it really is a step change not just an evolutionary upgrade. I’ll start with my summary for those of you in a hurry. If you read on past that list I go on to give advice based on the mistakes and experiences I’ve had with FW4. All the updates are positive with some features being more useful than others…….
