How to adjust the level of the background blur on macro shooting?
On Sony a6000 with e30mm macro lens, I recall last time I used it there was a button which lead to adjusting the intense of the background blur with a wheel. I believe, it was an AEL button. Today I wanted to get there again but AEL button is not working at all, except showing an asterisk symbol next to the ISO tab when I press it.
I spend so much time to google this and didn't find the instructions.
I hope someone can help me out?
