The optical system of Venus Optics Laowa 25 mm f/2.8 2.5-5X Ultra Macro ensures image magnification from 2.5 to 5x. It’s composed of 8 elements in 6 groups, and one of them is made of ultra low dispersion glass. The manufacturer emphasises that thanks to such a design we can enjoy an appropriate correction of chromatic aberration, as well as images characterised by high sharpness and high reproducibility of colours.
Apart from that, each element composing the system is covered with anti-reflection coatings, which should minimise light reflection and appearance of hot spots and flares within the frame. In addition, the overall contrast of photographs in challenging conditions will be improved. The depth of field is ensured by the 8-blade diaphragm with the range of f/2.8-f/16. The focal length of 25 mm, in turn, is responsible for the 10.3-degree angle of view.
Venus Optics Laowa 25mm f/2.8 2.5-5X Ultra Macro is sized 82 x 65 mm and weighs 400 g. Of course, it’s a fully manual macro glass, which offers an effective focusing capability ranging from 173 to 223.5 mm. The lens is already available for preorder with Nikon F, Canon EF, Sony FE and Pentax K mounts. It costs 399 dollars.
An interesting option is that you can buy an adapter for the Micro Four Thirds (M43) system, so also the users of small mirrorless cameras can tap the potential of this glass.
