Nice job especially on #3 and 4.
I use a Nicon 6T (62mm thread) on my FZ20 for close ups. About a year ago when I was experimenting I screwed my Tcon14B onto the 6T an discovered that I could get good macros from about 24" away. I would assume similar results could be gotten from other 6T and teleconverter combos.
Hrere is a picture of my watch with the 6T+Tcon14b at about 2 feet away
