... nice hexagons septagons (thanks Akari).
Df, Nikon SE 36-72mm 1:3.5, reversed as follows: 36-72, regular mountet 4 T, 21mm length metal lenshoud used as an extension (52mm lens side, 58 mm filter side), 58-52mm downstep ring, BR2
@ f/9.5 and t=1/250s
(notes may be not completely accurate here)
This combinations allows for brilliant close ups and macros. It has a strong tendency to produce septagons on any light source in picture or any stronly illuminacted contrast edge.
Working distance is on the short side but longer than with the 60mm AF-S G.
