Could anyone offer me some advice please. I use the X-T2 which I adore, with the 55-200mm lens. Mainly I'm a landscapist but one of my regular jobs is for some horse racing photography, some of which is in low-early morning light. I have been playing with focussing points but I'm having some issues with for instance a horses head (which is moving) keeping in focus even when i use the single point auto focus, or zone. In some cases the camera seems to lock on to the rider rather than the horse, even when I move focus points onto the horses face and I'm getting the in-focus 'bleep'. I'm shooting at the open end of the 55-200 usually at 200. I use continuous focus tracking on the front switch, option 2 in the focus tracking menu, and I'm still not hitting focus every time. Please could someone offer some help? I previously used full frame Nikon and the 70-200 which was a much faster lens, but I'm sure I should be getting more success rate with the Fuji than I am. I guess what I'm looking for are some fool proof settings that I can use as standard for this kind of photography. Any info gratefully received, thank you!
