With the help of a simple adapter, the reverse lens can be used as a free macro lens, but in this way, the lens and the body cannot exchange information, and functions such as autofocus and exposure settings cannot be used. However, a recent Canon patent will defuse these inconveniences. Recently, Canon published a technical patent in Japan on the lens equipped with two-way bayonet. With the help of this patent, both ends of the lens will be equipped with bayonet, one end of the bayonet will be used for normal purposes, and the other end of the bayonet will be installed to be used as a macro lens.
