The standard lens is the Carl Zeiss Planar 1:2 f=50mm in bright aluminium finish with a chrome 49 mm thread filter ring and an outer bayonet for Zeiss-Ikon filters. The lens focuses to 0.3 m (1 ft 0 in), which is closer than the usual 0.5 m (1 ft 8 in) for a normal lens. The focusing helical is remarkably smooth and precise.

It is more accurately known as the M42 × 1 mm standard, which means that it is a metric screw thread of 42 mm diameter and 1 mm thread pitch. (The M42 lens mount should not be confused with the T-mount , which shares the 42 mm throat diameter, but differs by having a 0.75 mm thread pitch.)
The traditional Hasselblad medium format film cameras capture images on 120 film in the 6×6 cm (nominal) frame size; the actual frame size measures 56.5×56.5 mm (2.22×2.22 in), which is larger than small format 135 film, with a frame size of 36×24 mm (1.42×0.94 in). This means the crop factor for most film-based Hasselblad cameras (based ...
Right and left were identical variable power lenses with distance and reading power centers in the upper and lower part of the lens, respectively. The glazing was made to accommodate eye position changes from distance viewing to reading. The point of reading is about 14 mm below and 2 mm to the nasal side in comparison to distance viewing.
The sequence of lens designations may differ in literature. See also full list of Nikon designations, Sigma designations, Tamron designations and Tokina designations.. Nikon AF-S/Sigma HSM/Tamron USD or PZD: The lens contains an integrated ultrasonic focus motor based on piezoelectricity, which enables quiet or low noise autofocus operation.
The Hologon was designed by Erhard Glatzel [] and others at Zeiss in 1966 [1] [2] and patented in 1972. It is a largely symmetric triplet with a fixed aperture; the original German patent application describes a lens with 120° angle of coverage and a f / 8 maximum aperture, while the US patent expands this to three related designs with different coverage angles and apertures (120° f / 8, 110 ...
