Playing with Lens reversals, stage 1

Since the fabulous Roni has made me revisit (and like) the world of lens-reversal close-ups, I thought to push it a little.

Took the standard setup, and inserted 68mm of extension tubes into the stack. Extension tubes help to decrease the minimum focus distance, so you can get even closer. Use with caution; you can get so close that you block light.

(Wobble-focus technique is in play for all of the following. Yes, I did have and carried a tripod, but I really need a focusing stage...)

Anyway, pointed the stack at a known reference: a U.S. quarter dollar coin
Testing, Reverse 50mm onto extension tubes, Known reference

Then pointed it at the ever-available Agapanthus bloom:
Testing, Reverse 50mm onto extension tubes

(this is the same bloom, sans extension tubes)
Testing, Reverse 50mm onto extension tubes (control)

And then, one for fun
Testing, Reverse 50mm onto extension tubes

At some point, I will try this with a bellows extension. Definitely need a tripod for that, but the bellows has a built-in slide, so it should be a little easier.

Now excuse me while I go clean my filthy sensors...o.O


  1. You had me at "fabulous". ;-) Then you made purple magnified! If you'll clean my filthy sensors too, you'll keep me forever. lol:)
    These are beautiful and you know it thrills me when you experiment with this. I like how you are pushing it ever further and it makes me happy that it intrigues you.
    Be inspired my brutha. It is good and I love it, and you.:) Thank you.

  2. thank you! playing is fun!

    if you trust me, i can clean sensors, yes. but i would consider getting it done by canon-authorized centers. should come back like new.

    sadly, a lot of my friends are on the canon side, so no can share gear :(
