Smooth Transition Focus optics

Smooth Transition Focus

Smooth Transition Focus (STF) optics produce images with high resolution at the plane of focus, melting away to beautifully diffused out of focus rendition.

Say goodbye to blur

Pair the lens with a camera by Sony featuring built-in SteadyShot™ image stabilisation and you’ll enjoy smooth, blur-free results when shooting handheld.

Refined optical performance

Special apodization elements cause the intensity of the defocused point light sources to fade out radially so that no sharply defined edges or geometry remain.

  • Smooth Transition Focus design with apodization optics

  • Sharp in-focus areas with creamy defocus areas

  • Smooth, natural highlight diffusion

  • Manual focus and aperture rings for total control

  • Minimum focus distance of 87cm
