Thank you Onyx, Glen and Birddog. Somewhere I read about reversing the lens and came across an article on the web (can't remember the link) where that guy mounted a 70-300mm lens on the camera and a 60mm micro reversed (lens to lens) and I decided to try, wholly smokes! it works, working distance is about 1" and magnification is about 7x. I don't have a macro coupler so I put the camera on the table and the 60mm reversed on the 300mm with a small piece of masking tape so it won't roll while shooting. I have 2 nice shots of a dime almost touching the lens quite nice (at least for me, just a beginner) and I am trying to find out how to post it here for feedbacks.
As to the tubes, maybe, but also considering a bellow so I can choose the working distance as needed.
Hang for my first pictures in a day or two
