About and Contact

We are a product development company based in Shenzhen, China. We aim to bring unique photography peripheral products to everyone through our own creativity.

MonsterAdapter was officially established in 2020 in the form of a company (Shenzhen Muohuan Optoelectronics Technology Co., Ltd.), but the team members have already developed many eye-catching original lens adapter products in the industry behind the scenes.

  • In 2013, the world's first Contax N to Sony E mount electronic adapter;
  • In 2014, the world's first Nikon F to Sony E mount autofocus electronic adapter;
  • In 2014, the world's first Minolta Vectis to Sony E-mount electronic adapter.

After the establishment of the company in 2020, MonsterAdapter officially released our first product: LA-EA4r, which adapts the Minolta/Sony A-mount screwdriver lens to the Sony E-mount cameras. This is the world's first use of the camera sensor to directly drive the screwdriver lens. Revolutionary product.

At the end of 2020, MonsterAdapter released the world's first and only Pentax K-mount to Sony E-mount autofocus adapter, which can simultaneously drive a screwdriver lens and an SDM/DC lens with a built-in motor.

While we as a company have not been established for long, we are fully committed to bring more innovations and surprises to the world in the future.
