Dear Bez, thank you so much for your words!
I will revisit the landscape idea, very good.
I used a total of 0.5 stacks for this one
Dear Akira, I always make the blurry ones.
First, I start making it in focus, then I deliberately move the focus a bit to make it creamy.
Then, when I review the images on the big screen, well, I get attracted to the blurry ones.
The 180/2.8 AIS is extremely sharp even with an extension ring.
Thanks!
