The original lenses were designed to cover a film area of 6cm x 4.5cm, this means that the lenses all cover the Alexa 65 sensor as standard. However, rehousing them with the built-in speed booster still allows the lenses to cover all full frame sensors, including LF open gate, while improving the speed of the base lens by one stop. The Mamiya 645 Sekor C lenses were developed during the 1970s and released during the second half of the decade. The lenses boasted a multi-layer coating and sharp, clean optics from corner to corner. They produce smooth out of focus areas and are well matched across the focal lengths. These lenses provide a bridge between the classic ‘vintage’ look and modern optical designs and coatings that manufacturers produce to date.
Focal Lengths: 17mm, 25mm, 32mm, 39mm, 50mm, 57mm, 78mm, & 107mm
