Im sure this question has been asked before, but ive done a search and I cant find the exact answer to my question.
I understand there are various manufacturers of these but I would like to know if there is a list of compatible lenses?
I have seen posts talking about canon lenses but nothing about sigma or tamron.
I have a tamron 70-300mm and wondered if this would be compatible with any of the makes on the market? ie kenko, jessops.
Many thanks
