You really need auto extension tubes the electrics of which are compatible with your make of camera.ie I have a set of Kenko tubes that are compatible with my Canon but they would not work with any other make.
None auto extension tubes will work but give no control of the lens, focussing or aperture or anything so a lens used with a none auto set-up would have to be capable of being controlled completely manually which is rarely the case these days regarding aperture control.
Be aware that depth of field is very narrow so when moving back and forth searching for the plane of focus it is all too easy to go right through the plane of focus and not even see it. The shorter the focal length of of the lens in use the greater the magnification and the depth of field is tiny.Sometimes it is even quite hard to find the subject let alone focus on it! Welcome to the magic of macro, a fascinating world but challenging.
