There are plenty of guys out there discovering the wonders of an 18-55mm mounted inverted on the body, with the help of inverter rings. It can yield great results, for it’s money. The main drawback, though, is that the lack of electric communication between the body and the lens means that everything becomes full manual.

More recently, I’ve begun noticing guys choosing to ruin a (maybe deffective) lens, to detach its back side, to glue it on the front of the lens and to join the contacts between the back side and the inner workings of the lens. It works fine (you get diafragm control back), but it’s destructive.

So I’ve taken the challenge of building myself a set of rings, complete with electric contacts, that could be attached to both ends of a lens, providing the best of all worlds: inverted lens, complete with all contacts, but detachable, without ruining the lens.

Here’s a gallery of what resulted (and yes, it works!)
