Description — Lensbaby Composer Pro II 50mm f/2.5
The Lensbaby Composer Pro II with 50mm f/2.5 Optic is a prime, manual-focus special effect lens built for mirrorless camera systems. It covers a full-frame image circle, making it suitable for use on high-resolution full-frame mirrorless bodies. The f/2.5 maximum aperture gives photographers a useful degree of light-gathering capability for a manual specialty optic.
At 50mm, it occupies standard focal length territory, lending itself well to portraits, still life, and everyday creative shooting where selective focus can transform an otherwise ordinary scene into something visually distinctive. The lens features a 46mm filter thread, keeping filter costs manageable. It weighs 357.4 grams and has no image stabilization, consistent with its deliberate, manual shooting style.
The mount is specified as Lens Board (Technical Camera) — verify compatibility carefully with your body and any required adapter. There is no autofocus on this lens; every focus decision is made by the photographer, reinforcing the hands-on, craft-oriented nature of the Composer Pro II system.
