Kenko Extension Tube for Canon EOS AF Mount
Kenko Extension Tube for Canon EOS AF Mount - When you combine this inexpensive extension tube (filled with the same “low dispersion” gas as the actual Canon tube), you can use Canon EF lesnses (I don’t know if EF-S lenses work) to do macrophotography.
If I bought one of these, we could do a “name this thing when all you can see is a tiny zoomed part of it” series on tumbledry!
