A modern version of the 1955 L-mount Summaron 2.8cm F5.6 lens is to be introduced by German camera manufacturer Leica. The new lens will be fitted for the current M series and will be named the Summaron-M 28mm F5.6. The company appears to have kept the optical design the same as was used in the original model – and indeed makes a feature of the vignetting - but has changed the mount and added 6-bit coding so the lens can communicate EXIF data to modern camera bodies. Internal mechanics remain as they were when the lens was first introduced, but the aperture ring and focusing knob have been redesigned to match the placement and feel of the current M series optics.With such a small maximum aperture the lens itself is especially compact and lightweight - measuring 51mm across and extending 18mm. This makes it ideal for street and documentary work on occasions when the photographer wants to remain unnoticed. It seems though that at this stage the lens will only be available in silver chrome, like the original, with no black paint alternative for those with black cameras.Leica says the focus throw is particularly long which should make focusing accurate, and the small aperture will deliver quite an extensive depth of field even when used wide open. The closest focus will be one meter and the smallest aperture will be F22.The original Summaron 2.8cm F5.6 was produced between 1955 and 1963, and was made in relatively small numbers – so prices have remained high for these older models. It was introduced as a replacement for the even flatter Hektor 2.8cm F6.3 and bought with it that faster aperture.There is no date for delivery yet for the new lens, but the company is asking users to pre-order due to ‘expected strong demand’. The price will be £1900.
Beautiful lens but sample pictures are a bit disappointing. Anyone interested in this lens?
