John, as I read on forums from my country this lens is very good.
Can you please search in the most known photography forums known to you and tell me how good it is?

As I read, I will need to close the aparature as much as possible, but on the S5 I can only to 8F.. so I dont know if it will be good for me
It's neccesery because the DOF will be very very shallow..

And the lens will allow me to do macro from farther than without, right?

Thanks.
