This set up uses the Panasonic 12-42 Mega OIS with two close up lenses:

1. Subsee +5
2. Nauticam CMC-2

The subsee is relatively weak and covers the area where the lens stops focussing up to around 15 cm, for more magnification I use the CMC-2. It is not necessary to have anything stronger if using the ex tele mode that gives additional 1.35 magnification.
