Hello people!
This evening I wanted to test some reverse macro with my 50 1.4.
As usual I had just like 10 minutes to waste, so this is the best I got so far.
I took these picures with my lens set to f/18 or f/22, so I had to go for ISO 800.
It's quite a nice result anyway. Of course a specific macro lens must be much better, but I think my 50 could be used in emergency

Pencil tip, I swear it was really small.

Same picture, shown on 80% crop.

A blueberry, it was just slightly bigger then the pencil tip:

And this time a 100% crop.

There's a lot of noise due to the high ISO, and a lot of chromatic aberration.
I still think I can get something better just to have some fun.
