You mean Teleconverters (TC) and not extension tubes. Extension tubes allow the lens to focus more closer than it usually can - allowing macro work, whereas the TC's extend the focussing distance of a lens. (Although it seems common to use both in combination from what I gather) I am sure there are others more capable who may be able to answer better about using TC's with 70-300 Non L, here is food for thought: http://bobatkins.photo.net/photography/reviews/tcs.html http://www.photo.net/bboard/q-and-a-fetch-msg?msg_id=000CY8 - Harman __________________________________ Do you Yahoo!?
