I have a D600 and a 105mm VR, and I want to use the ES-1. Near as I can figure with a 1ft minimum focus distance on the 105, I will need about 5-6" of threaded extension tube (lens is 4.6" long and ES-1 extends to about 2.5"). The VR will go to 1:1, so I'm thinking this will work.
My problem is finding the extensions. All I can find are 43mm threaded tubes. Anyone know where I can get 52mm or 62mm with threads on both sides? Stacking 5-6" of filters with the glass removed means a lot of filters, so I'd rather not do that.
Note, I've seen the services, but I don't have thousands of slide to do. Plus, I kind of want to experiment a little. Will I be wasting my time and money?
