Referencias

This Midland lens expanded the range of the Leicaflex lenses with an additional focal length and at full aperture it shows medium overall contrast. Performance is very even over the whole picture area. The lens does its job in a competent but unassuming way. This was the longest focal length with automatic diaphragm operation in its time. The lens is a heavy one and very solidly built in the best Leitz tradition. The 1970s were the period that Zeiss and Leitz battled for supremacy and produced the best mounted lenses in the world to fence off the cheaper Japanese phalanx. Engineering ambition was more important than photographic convenience.
