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:
- Traumflieger reverse lens protective filter (Canon)
- Traumflieger reverse lens protective filter (Nikon)
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.

When looking for reverse mounting a lens, I have had the same issue, where I wanted to try macro but did not want to leave the lens open to dust or damage. The option I came up with was to modify a rear lens cap. What I did was to use a 50mm hole cutter to take out the center of the rear lens cap. I then trimmed down the remain wall to open out the hole size so I could screw into place a 52mm filter. To be honest it was harder then I thought to "screw" the flter into place but I used some sandpaper wrapped around a tapered cup to smooth out the trimmed hole. The taper on the cup then allowed me to open up the hole size to clamp the filter into position. The thread on my filter was 52mm so i opened out the hole size to 51.5mm. This allowed me to force the filer into place without the risk ofr cracking the cap or filter. This is a cheap option which can be mounted on any EF mount lens, I also use a 52mm lens cap on the cap so this also keeps finger mrks off the filter lens. Hope this helps you all out there.
