Laowa 105mm f/2 STF Lens - Canon

Laowa 105mm f/2 STF Lens (Canon) – Smooth Trans Focus for creamy bokeh and enhanced subject isolation

The Laowa 105mm f/2 STF lens for Canon is built for photographers who prioritise background rendering and precise manual control. Designed for full-frame cameras, this lens focuses on portrait, event, and fine art photography where smooth bokeh and subject separation matter. It combines a dedicated Smooth Trans Focus (STF) optical design with a robust metal housing to deliver consistent imaging characteristics and reliable handling.

STF design and optical construction

The lens uses a Smooth Trans Focus (STF) design that incorporates an apodization (APD) element. As a result, it produces uniquely smooth, creamy, and dreamlike background bokeh. In other words, out-of-focus areas render with a soft transition that helps subjects stand out.

Its optical formula consists of 11 elements arranged in 8 groups. This construction aims to deliver strong sharpness, clarity, and colour fidelity across the image. Together with the 14-blade aperture, the lens yields virtually circular highlights and consistent bokeh quality.

Aperture, focus and handling

The Laowa 105mm offers an aperture range from f/2 to f/22. The bright f/2 maximum aperture provides flexibility in lower light and gives creative control over depth of field. At the same time, the lens is a manual-focus design, allowing photographers to make meticulous focus adjustments for critical portrait and fine art work.

Built with a durable metal housing, the lens is designed for professional use and frequent handling. The solid construction enhances reliability during demanding shoots and regular transportation.
