Extension Tubes or Canon Close-up Lens Adapter?

[Jon Ruyle]

I thought the OP was deciding between 24-70+extension -VS- 70-200+closeup. If 70-200+extension was an option, I might have given a different answer.

Ah... soundhound did say that, you're right. I don't tend to like to use shorter lenses with extension tubes because there is so little working distance.
