Lens magnification tests

I've been experimenting with reverse mounting lenses on 160mm extension tube. I took shots of a Lego block.

 

From top to bottom we have.

 

Pentax-A 100 F2.8 (no extension tube)

SMC Takumar 55mm (reversed)

SMC Takumar 35mm (reversed)

SMC Takumar 28mm (reversed)

DA 15mm (reversed)

 

The magnification ranges from 1:1 to approx. 1:12
