Canon 1100D with m42 lens for macro.

[Stan Hesketh]

Hi folks, a quick question if I may.
I used to do some macro with a Zenit last century, still have the setup (and the Zenit ), and have bought an M42 adapter for the 1100D. I have the extension tube set which all works great (the M42 lens can be stopped down manually.)
I notice some people use a reversing ring as well as the tubes. What is the advantage of using a reversing ring along with tubes? Does it just increase the magnification over the tubes? Any other tips for M42/Canon setup?
Many thanks.

Reversing a lens acts a bit like adding another extension tube in that it moves the glass in the lens farther away from the film/sensor plane. Here's a good explanation of the process - https://photographylife.com/focal-length-in-reverse-lens-macro-technique

Thanks John that's great Reversing rings are so cheap on Ebay, I will get one anyway and experiment.

One caution. The delicate part of the lens will now be stuck out front for all the world to abuse. Be very careful when using a reversed lens.
