Yes, the Vivitar 2X macro TC is a very good all-around TC, and the macro function is quite effective on some lenses, too. However, the use of the AT-X 90/2.5 Macro's 1:1 Macro Extender (or of the optically identical VS1 90/2.5 Macro's 1:1 Macro Adapter) with another lens seems to me to be more intriguing - macro focusing without doubling the FL and without doubling the f-stop. > I believe it's a 7 element convertor....
