Lomography has launched its new Neptune Convertible Art Lens System, which is a single lens system that includes three interchangeable prime lenses at different focal lengths.

The three lenses that comprise the Neptune Convertible Art Lens System are the Thalassa 3.5/35mm, Despina 2.8/50mm and Proteus 4/80mm.

Lomography says the design is inspired by Charles Chevalier’s first convertible lens from the 19th Century and allows photographers to mix and match focal lengths, f/stops, and special aperture plates to adapt the Neptune Convertible Art Lens System to your subject.

Its design features a seamless iris diaphragm aperture mechanism, Lomography says it is an expandable lens system with possible focal lengths from 15mm to a 400mm monocular.

The lenses offer close focusing distances of 0.25m (35mm), 0.38m (50mm), 0.8m (80mm). Lomo says the Thalassa 3.5/35 Art Lens is aimed at architecture, street and urban scenes, while the 50mm Despina is best for fashion and everyday. The Proteus 4/80 Art Lens is aimed portraiture and nature photography.
