macro extender for DA lens

DA lens has no aperture ring, so with cheep (6USD) extender DA40/2.8 or DA70/2.4 is impossible to control aperture. as all DA lens...

but some upgrade is possible, just need to add aperture ring to extender!
here is the photos...

so, now I can mount on this extender all kind of DA lens and FA still possible to.

extender minimal length is 21mm, maximal length is 63mm.
maximal distance of focusing with DA40/2.8 Limited is approx 100mm,
scale approx 1:2.

maximal possible magnification with full stock of rings is 2:1
it is a 10mm scale

just needed to paint it black, tomorrow may be...
