Mike, your specific questions were already answered very well and extensively. Thus, let me just add that the important part of the product's name is "macro" - not "tele". The converter will turn your nifty-fifty into a manual but otherwise fully fledged 3.5/100 macro lens capable of shooting 1:1 macros. As such, particularly with the lens stopped down to its sweet spot of f4.0-8.0, the combo works very well. It is probably the best "macro on the cheap" solution around. Happy shooting.

Hi Hannes. Magnification depends on the lens. The SMC 50mm has a native magnification of .15X. Adding a 2X TC doubles the magnification to 0.3X, which is 1:3 macro, not 1:1.

"Best" depends on one's priorities. A Raynox diopter is best in some ways, extension tubes are best in some ways, reversing a lens is best in some ways.

IME, a 2X TC degrades IQ more than a Raynox 250, and the Raynox is more powerful. I removed the glass elements from a Vivitar A 2X TC to use it as an extension tube with Auto metering, because it has better IQ without the glass and is very versatile for closeups and macro shooting. The Kenko with glass removed would provide higher magnification, but of course would no longer be useable for tele. Reversing a lens is the cheapest solution of all, provides excellent IQ and true macro magnifications, but very tight subject distances. Which is best depends on what one is intending to shoot.
