Lets see em.
A few beginners have been asking about macro.
I thought this thread might give a good idea of how far you can push the limits of macro.
As well as aid those looking for equipment advice.
Wouldn't mind seeing a few reverse ring setups to help with this.
Below is the Pentax K5 wearing a 100mm WR macro on top of a 25mm extension tube and topped off with a Raynox 250
and the Pentax AF160 ring flash.
Thanks for posting the list of the pieces of gear ... that helps.

I really want to try some macro photography at some point, and my next lens purchase (at some point in 2012) will be a macro lens, and some sort of lighting setup. Still working on learning exposure properly, so that's a ways off.
But being the noob that I am here, what is the purpose of the extension tube? What is the effect of adding it to the setup?
Thanks,
Kevin
