The HELIAR 40mm F2.8 Aspherical M39 is a compact wide-angle lens with a 5-element lens configuration in 3 groups. Thanks to the latest optical design, the diameter of the filter is 34 mm, the total length is 20.2 mm and the weight is only 110 g.
The classic design is complemented by the optical arrangement, the lens also has an aspherical element to reduce spherical aberrations and distortions for remarkable sharpness and detailed images. The manual focus design of the lens allows you to photograph subjects up to 70 cm away.
The unique 40mm focal length offers a 57° angle of view, which is slightly wider than the classic 50mm length, but narrower than the standard 35mm wide angle. The rounded aperture of 10 blades contributes to the bokeh experience, ensuring usable optical power from the maximum aperture.
