ФОТО: dpreview.com

Lomography has launched the Lomogon 32mm F2. 5, a compact lens with full frame sensor coverage and a unique wheel of aperture stops that protrudes from the barrel. Fitted with the Lomogon Circular Aperture Disk the lens uses a series of five round holes cut into a disk of metal as its aperture control.

The toothed disk sticks out from the lens and is turned by the user to drop the desired hole behind the front element – a bit like Waterhouse stops from the 1850s. The holes in this disk correspond to F2. 5, F4, F5. 6, F8 and F11 – and each is completely round as they aren’t created by an iris.

The Lomogon uses 6 coated elements in 6 groups, has a 62mm filter thread and a closest focus distance of 0. 4m. Developed with Russian manufacturer Zenit and built in China, Lomography says the Lomogon uses ‘the finest glass optics’ and is assembled by hand. The result, according to the company, is high micro-contrast and ‘enhanced colors’. It will be available in Nikon F and Canon EF mounts, and adapters can be used for other camera fittings.
