If you’re looking for an X-series AF tracking test using a manic springer spaniel as the test subject then you are definitely in the right place! My spaniel, Charlie, is the ultimate test subject that I put all my cameras through to determine their auto focus capabilities and limitations. This was previously conducted when i moved from a Canon 1Div to the 5Diii, which was dramatically better, with a very high hit rate using the wonderful Canon 70-200mm F2.8 IS ii. Now the time has come to test the Fujifilm X-T1, 55-200mm lens and a prototype of the 18-135mm lens. I did try this test with the X-Pro1 about this time last year and the results were almost laughable… The X-T1 is an entirely different beast. What I have found so far is that once it locks on to a subject this camera is very good at tracking and seemingly with all Fuji lenses. However, there’s tracking and then there’s Canon 5Diii AI Servo… So how did the X-T1 and the latest telephoto lenses hold up against the ultimate action combo? Well I have to say I am extremely impressed by the results. So much so I’m not sure whether people can tell the difference. Each camera was set to ISO800, F5.6 (yes I know this means the 18-135mm was wide open) and used centre point continuous focus. Each lens was fully extended.. I didn’t hold back the zoom of the 55-200mm, woops forgot the crop factor………
