Cartridge type attachment lens for a digital camera |
摘要 |
A cartridge type attachment lens is arranged in front of a digital camera for receiving card lenses. A cuboid shaped shell is removably attached to a camera lens. A battery and a lighting unit as a light source for the close-up photography are in the shell. A plurality of parallel slots are each disposed on one lateral side of the shell, and each slot extends inwards to form a sliding groove in the shell for accommodating the card lens. Multiple card lenses can be inserted the shell to form arbitrary permutation and combination.
