Dear Dedicated Wildlife Shooters,
Please don't buy a Z63. It won't match up to your Z8 or Z9. Your cat will scowl at you. Your cat will leave hair all over your Z63. It won't cycle your cat food, and it won't recall which food your cat likes best.
What it will do is make a light travel kit that will give you lots of low light possibilities, and might help as second body wildlife camera, especially for those that can't afford the low light, fast $15,000 primes and those not looking to print super large. Those with the 600PF and 800PF might have much cleaner images.
My coffee cat, Cortado, and I have watched all of the skateboard videos. He told me that the Z63 will capture his whiskers beautifully as he zooms by at sunset, and he said mom might even pick up a lighter camera. Cortado pressed the pre-order button.
We will be surprised if the Z63 ever gets bird, RSH, or Cycle AF. Cortado and I will consider that a gift if we do.
Just some perspective from a coffee cat.
