Thanks
@Steve for another very useful video. After watching your 600PF review I decided to keep my copy rather than return it and buy the 400 F4.5 instead. I went with my Z8 and 600PF for its first walk today during a gap between the rain showers. I found the weight ideal on a long walk and the combo fitted in my shoulder bag that I had purchased for my 500PF.
I am also waiting for the bird detect to be ported to the Z8

.
Regarding recall shooting function do you think swapping between animal and bird is the best choice for the limited quantity of one for the recall shooting function? I currently have recall shooting function set to switch subject detect on or off.
