Laowa 28mm f/1.2 FE Announced

By Louis Ferreira | Published: March 28, 2023


Venus Optics just announced its Laowa Argus 28mm f/1.2 FF that you can buy directly from Venus Optics.

The Laowa Argus 28mm f/1.2 FF has a modern take on the classic and versatile 28mm focal length. Rendering impressive sharpness and optical performance even at wide-open. Work beautifully as an everyday lens in the day and in low-light situations as well. The slightly wider AoV(compare to 35mm and 50mm) can be handy when doing street, landscape, and even environmental portraits. A 62mm filter thread is available for any screw-in filters, giving photographers the option to create shallow DoF images even when the sun is up. The lens itself is only about 562g and 68.5 x 106mm in size. Making it an excellent travel companion.
