For occasional use of the macro, cheap, these extension tubes which are not expensive at all, permmettent magnification coupled to the objective of your SLR. We leave the macro-proxy for real photos macros. There is no connection, so the development and any adjustment is made in manual mode, which is done very well. The manual fails to mention that the small screw allows unlock the extension tubes to detach the whole picture box. Quality is what it is. So cheap, the macro becomes available.
