I've started reversing lenses for macro photography and I'm loving it, but something bothers me: a lot of articles say that it exposes the rear element of the lens. Are there protection rings available for the rear element when using a lens this way or do I need to do it myself like this one: http://www.instructables.com/id/Reversed-Lens-Filter-Adapter/? It seems nice but, even if I like duct tape, using it for something relative to light leaves me uncomfortable...
Hallo I have found reverse lens protectors for Canon and Nikon on a german website. The best thing about these are you only have to buy one, and you can use it on all your lenses.
you can buy them here:
The protection ring is attached to the rear of the lens (the lens is in reverse position via Retro Adapter Professional), where it holds a protective filter with 58mm thread (for UV filters, glass filters or polarizing filter) on.
Thus, the rear lens is protected against scratches and the electrical contacts are reliably protected against dust. If you do not have filters, you can also order UV filter.
