First day out today with the new setup. The A1 AF is really impressive, especially compared to the Z9. Could track even the fastest flying birds with ease. Took a few thousand photos and all 99% were in focus and insanely sharp regardless of conditions.
Two minor points about the A1 body = its tiny in my hand so not the most comfortable to hold. The battery life is also much worse than the Z9 which I'm use to so that'll take a while to get use to.
One major point - buffer write speed to an SD card, whilst usable, its quite hard to get use to coming from a Z9. The Z9 writes to the compact flash type B cards insanely fast whilst I'm stuck with SD on this until a large enough type A which isn't "lens money" comes out.
The 600mm F4 GM OSS is insanely good though, no real negatives or minor points with it. The new drive motors made my Nikon 800mm F5.6E FL seem like a toy which I wasn't expecting at all. Due to the focus speed, bird in flight stuff is more down to technique than technological capabilities now.
