Buddleia Macro

I recently purchased a second-hand canon life size converter to be used with my canon 50mm macro lens which increases coverage of the lens form approximately 1/4 x life size to full macro  (1x). I was testing it out yesterday in the garden on our magnificent buddleia shrub (actually it's more like a tree as it stands about nearly 12 feet high). The best of the blooms are gone but there are still one or two to photograph. As you can  see you can zoom in quite close and blur the background nicely
