Thank you Oivid, symmetry was the key for this shot
Tom very nice shot especially the second

Thank you Arturo

and yes Swallows are in my list since last year

I spend a couple of hours in a small lake to be able to have a good photo of shallow touching down the water for insects

It was very challenging, the Z8/180-600 was heavier than Z8/500pf used last year and slower AF

so almost impossible to use EVF
But I found a workaround: I used precapture 1 sec with 30 FPS (jpeg

) and trying to guess where the bird is without using EVF or back monitor, just pressing 3D AF button and shutter almost continuously

it worked!!!
