I used the 36mm extender on my 70-200mm 'L' series 2.8 Canon lens for these - the lens was then able to come into focus about 100mm from the subject
Hope this is of interest Billi ?

do you think it would matter about the brand? Ebay has them for cheap, but I don't know if that would mean they're of poor quality. It's definitely a great alternative to spending heaps on a new lens!
