I used a rear lens cap, cut the center out of it and epoxied a filter ring (a step-up or step-down ring would work) to it. I have no intention of using a filter, instead I attach a ring light to the reversed lens.
That's what I figured I would end up doing - only was more leaning on the side of welding it. Although, earlier, someone mentioned that there was something called a "Reverse Ring Light Holder K", so I will check that out too. Kostas - please tell me where you ordered this from? Rebekah
