The 75mm f/1.5 Biotar Swirly Bokeh lens from TTArtisan is a classic design with the well-known optical twist. This fantastically designed optic is a unique short telephoto lens designed for M42-mount cameras by the engineers at TTartisan. The fast maximum aperture value of f/1.5 not only helps capture images in low light conditions, but also allows us to create impressive portraits simulating beautiful, swirling, swirling movement in the background. This manual focus prime lens allows us to work with subjects up to 75cm away.

Built for durability, the rugged metal and glass 75mm f/1.5 lens is made from aircraft-grade aluminum and features a metal lens cap of the same material for added protection. With the optional lens mount adapter, this lens is easy to use with almost all camera bodies. Unfortunately, it cannot be adapted to Nikon F-bayonet cameras.
