Marelux MV-15 and MV-10 closeup lenses

Marelux now has MV-10 and MV-15 closeup lenses with a flip adapter coming. The two lenses can be stacked to give a value of +23.

I shot both with the Sony A7R V and Sony 90mm macro lenses in manual focus set to 1:1 using focus peeking for focus. I also used two Marelux Apollo III strobes for lighting set to manual. 

First photo is the lens at 1:1, followed by the MV-10, MV-15 and MV-10 plus MV-15 stacked. You can see the size difference in the last photo.
