Moving to mirrorless?

I watched in youtube a comparison of z50 (cropped sensor) with x1.4 teleconverter and a 300mm lens that gives you a reach equivalent to 630mm
with a z6 or with a x2 telenconverter and the sane f/4 300 mm PFlens which gives a reach 600mm.
The results may surprise you. It is titled as follows:

with a z6 or with a x2 telenconverter and the sane f/4 300 mm PFlens which gives a reach 600mm.

Quote:Yes the z mount 600 lens, but wanted info on z9, how to you find it? Do you use it for birds? Any good for flight shots? Thanks
As yet I have not done extensive BIF work with the 800 PF - which is the limit of my budget.
Your combination is about an another £9,000.
There are plenty of images on specialist forums showing in the hands of experienced BIF photographer the Z9 and 600 S is a superb combination.
The ability of the camera AI to detect a bird, then the head, then the eye all in a fraction of a second and the cameras ability to track rapidly moving subjects seems to be excellent.
Success is influenced by a photographers ability to keep the subject centred in the selected AF zone - which as I expect you know in view of your budget is where a Gimbal for long lens work can make a difference
