"I used the end part of a nikon extention tube like this one..."
Can you point me to the exact Tube on Ebay if possible, there are so many, some for the DSL/SLR camera models. I'm not sure which one to buy. Thanks for your help in advanced.
So it's attached to the spacer or is it on an empty filter, because 1 pictures shows another ring in front of the macro and another shows the macro strait into the spacer.........
BTW, your adapter is EXTREMELY impressive and for only $250 bucks, it's awesome, When I seen the video I was blown away, yours and www.holyzoo.com make some of the most impressive images outside of a professional, I wish I knew how to make one but some plans would be nice........
