Meike 50 mm T2.1 FF-Prime Cine at a glance

The Meike 50 mm T2.1 FF-Prime Cine is a manual-focus 50 mm prime for full-frame mirrorless cameras. Its T2.1 aperture leaves room to work in poor light and to separate the subject from the background.

Optics and rendering

The optical design uses 12 elements in 8 groups, with a 11-blade diaphragm that keeps out-of-focus highlights round. The aperture runs from T2.1 to T22, and the minimum focusing distance is 0.6 m.

Handling and build

Focus and aperture are set by hand; the lens has no electronic contacts, so the camera must be set to release without a lens. The filter thread is 77 mm and it weighs about 1.09 kg.
