Press release:

Venus Optics unveil the Laowa 25mm f/2.8 2.5-5X Ultra-Macro, an affordable extreme macro option for full frame cameras

Featuring a small lens barrel, lightweight design and extended working distance, the new Laowa lens provides an extreme macro photography option for DSLR & Mirrorless cameras.

Anhui China, Mar 27, 2018 – Venus Optics, the camera lenses manufacturer who had previously launched a number of unique macro lenses (60mm f/2.8 2:1 Macro & 15mm f/4 Wide Angle Macro), is proud to add another member to their macro products line, the Laowa 25mm f/2.8 2.5-5X Ultra-Macro Lens.

The new Laowa 25mm f/2.8 provides a magnification range from 2.5:1 to 5:1 and offers a flexibility for photographers to capture macro subjects with different sizes. The 8 elements in 6 groups design with 1pc of low-dispersion element, creates an outstanding image sharpness across different magnification and greatly reduces the chromatic aberrations and color fringing. The wide focal length gives a relatively deeper depth of field than lenses with longer focal length. This feature is particular essential for photographers who can then stack less images for achieving even sharpness across the frame.

Dedicated solely to macro applications, the lens is carefully designed with an extended working distance (40mm @ 5x) & small lens barrel. This design is aimed to provide sufficient room for lighting reaching the subjects. The lens weigh less than 400g and the compact size make it suitable for shooting both in the field and in the laboratory.

An optional rotating tripod collar is also released for photographers to benefit from mounting the lens onto tripods and compose at different angles.

Canon EF, Nikon F, Pentax K & Sony E mounts are available for order through Venus Optics official website (www.venuslens.net/) & authorized resellers. The suggested retail price (tax excluded) in United States is USD 399/pc. Pricing varies in different countries.

The new lens will be available to try in the UK Photography Show Birmingham during 17-20 March 2018.
