Brightin Star 28mm F2.8 Full Frame and dedicated UV filter (new) Note: Since it's not an option, It's for Leica-M mount. Purchased during a business trip to China, opened once and put up for sale because it didn't suit me personally. Although unused, there is no instruction manual, so I will consider it as "like new". The official dedicated UV filter is also included. This is a perfect item for a lightweight Leica M series body. Or, you could try using it with a mount adapter. It's a gold and black item with a cool appearance. From Amazon: Main Features: 【Retro Elegance】Paying homage to classic photography, it embraces a timeless retro look.
