The Fujifilm XT1 has been main my main body for wedding photography for the past 12 months or more. From the very beginning it has impressed. I've seen no difference in the quality of images provided to my clients since switching from a full frame DLSR and in many cases I think I get superior results. Fujifilm have released several firmware updates since its release, the last major update was version 3.1. this added several new features such as a electronic shutter. This is perfect for documentary wedding photography as it allows the camera to operate completely silently and with shutter speeds up to 1/32000s.
Fujifilm have now released the next firmware update for the XT1, Version 4.0. It again adds many new features but the most important to me (and probably every other user) is the completely re-vamped and improved auto focus system. I was able to test this firmware in the real world last week during a wedding, specifically the confetti throw. This can be one of the most demanding events to capture as a documentary wedding photographer because the moment is un staged and if you miss it...it's gone.
Here is a series of images from the complete confetti throw.
56mm 1.2 wide open at 1.2
AF Zone Focusing "C"
The result was pretty impressive and to be honest, effortless with the new firmware. The focusing followed the bride and groom with no problem at all, only missing them once when a handful of confetti jumped in to focus zone.
