This is something truly exciting! I've been trying to find a way to adapt medical lenses to my cameras for a long time, and I've finally cracked it.
This is a medical Laparoscope, normally used in surgery. But this particular model will be used to explore the inside of extremely rare violins and violas....
It's currently mounted on an old Lumix GX8, as the real camera I've been testing it on is a prototype which I can't give any details about.
Stay Tuned! (sorry for the pun)
