ES mode : I was photographing Kingfishers this weekend and wanted the 20frames/sec ES mode gives as the birds dive really quickly so frame rate matters. Got some great images however the one attached is an example of a challenge. The birds wings are backwards, in the reflection they are forward's. So on seeing this a quick google highlights that Fuji do not recommend ES mode for fast moving objects so fair play its a known limitation. What I don't understand is why using the mechanical shutter would remove the scan delays. This image was taken at 1/2000 sec, images shot in portrait mode don't have the rolling shutter effect. Also images shot at 1/8000 are pretty good. Overall I am happy this is a fairly narrow use case and the images stand up well against the fellow shooters using Canon 1DX mark 2 which shoot at a lower FPS. Does anyone know if the scan times are different when using the mechanical shutter. I think the best option is to use Portrait mode, the dive in was fairly predictable where the bird emerged was slightly more variable and landscape orientation gives a little more flexibility. 20FPS by the way generally gives a shot with the bird emerging from the water, one just clear and sometimes a third before it disappears out of frame. the DSLR's at 12FPS only really got one, so the issue of the reflection isn't show stopper. It may be worth mentioning that I don't have photoshop and this is an export of a raw file default profile through Capture 1 so not really post processed.
