04 Aug Testing the X-T2 Autofocus System on Bass Rock

The main advantage of the Fujifilm X-T2 is the new continuous autofocus system that the brand new camera has.  I have used it extensively over the past three months on motorsport subjects and I also ran a test on the Isle of May a few weeks ago, follow focusing the small and agile Atlantic Puffins in flight around the island.

Last Tuesday I was able to further test the Continuous AF on on the X-T2 by photographing the Gannets flying around Bass Rock.  Now Gannets are much larger and are easier to track than the small Puffins, but because there are so many birds in a relatively small area, following these seabirds presented several challenges for the X-T2.

Now the X-T2 has a customised AF-C function where you can select one of five presets in the menu and also have a sixth custom function where you can override the presets if you wish.  

Camera Settings
For the birds on Bass Rock I used two different settings.  Set 5 which is for erratically moving and accelerating / decelerating subjects, or Set 2, which is to ignore obstacles and continue to track the subject.   I tended to favour Set 2 on Bass Rock.  For motorsport I favour Set 3, which is for accelerating / decelerating subjects.

The X-T2 was set for manual exposure with either the XF100-400mm f4.5/5.6 or the XF50-140mm f2.8 lens fitted.  I used the 100-400mm on the island and the 50-140mm on the boat.  I used Zone Focus with a 3×3 square selected, which
