I have a 28mm f/2.8 and it close-focuses to about 1 foot. I want to be able to focus closer, but I can't find any solid information on Canon's extension tubes. Anyone know how much closer I would be able to focus with the EF25 extension tube? Will having one with my lens call for an exposure adjustment? Thanks in advance for any help.
