Two (2) Reasons Why the AF-Tracking of the X-T2 (and X-Pro2 Ver.2.00) is Much Better Than on the X-T1!
From TheCameraStore to DigitalRev… most X-T2 reviewers so far seems to be impressed by the new Fuji AF-speed, especially in continous shooting mode. So the question is: how was it possible to achieve such a significant improvement? There are two main reasons, as Fujifilm explains here:
Reason 1 for better AF-Tracking
“The new technology has been developed to allow increased number of AF search between the frames. There used to be only one AF search between the frames, but this is now increased up to 10. This will allow better tracking on the moving subject between the frames. […] longer live-view means that AF search can be conducted for longer period of time.”
Reason 2 for better AF-Tracking
“The AF search can now be processed in parallel. The breakdown of AF search is “Exposure”, “Read”, and then “Process”. The new algorithm allows so that each step can be conducted simultaneously. It means that while the first AF search is being “processed”, the second AF search starts to “read”, and the third AF search starts the “exposure”. By doing so, multiple AF search is now possible in the short interval.“
NOTE: The X-Pro2 will get the new AF-algorithm via Firmware Update in October 2016. However, the AF-C Custom Settings, introduced with the X-T2, will not be part of the Firmware udpate. If you don’t know what the X-T2 AF-C Custom Settings are, check out this Review.
