The redesigned 100mm f/2.8 lens is due to go on sale in December, 99 years after its first appearance.

The Trioplan 100mm f/2.8 lens is aimed at nature, portrait and macro photography.

It will be available in Canon and Nikon DSLR mounts and will also be compatible with Fuji X, Sony NEX and Micro Four Thirds-mount CSCs.

The German-made lens is also expected to be out in Leica M and Pentax K versions.

Dr Stefan Immes, who is behind the launch, said: ‘First tests show that we have managed to keep the extraordinary charm of the lens.’

On the Kickstarter website, project managers add: ‘Think of it as a special brush used by a painter, as it is a lens that creates art… Besides its wonderful bokeh, which appears in backlight situations, when it is used wide open at f/2.8 it achieves a balanced sharpness with a wonderful soft texture in out-of-focus areas.’

Specs as listed on the project’s Kickstarter website:

• Focal distance: 100 mm
• Maximum aperture: 1:2.8
• Focusing distance: 1m
• View angle: ±12° (full format equivalent 24 x 36)
• Filter: 52mm
• Number of aperture blades: 15
• Available mounts: Canon, Fuji X, M42, Micro Four Thirds, Nikon and Sony E
