I like the second one the best.
Thanks. I think I do too. I'm photographing it almost every day as it blooms. More images to follow as it opens up.
Looks like a successful experiment to me.
Overall, the A9 does better than the higher megapixel A7R4. Sometimes more megapixels are not a good thing. At the 600mm focal length the A7R4 requires a very steady hand and higher shutter speeds.
When the weather clears, I plan to use a tripod and see how that works.
