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.
