Sony’s very reasonably priced SCL-PK6/M (metres) pack of six high-quality prime lenses promises excellent colour rendition, low distortion and mechanical durability. The first cinematographers to have had the opportunity to get their hands on the lenses and shoot films with them have been somewhat overwhelmed by the results.
The focal lengths of the lenses are 20mm, 25mm, 35mm, 50mm, 85mm and 135mm with all having an open aperture of T2 enabling images to be captured in extreme low-light conditions. The T2 aperture also enables full control of selective depth of field, making it possible to shoot with shallow depth of field to produce a beautiful bokeh (the out-of-focus area of an image).
The lenses sit in robust, metal housing and all except the 135mm lens have the same compact design and the same front diameter and lens length. The geared lens rings are all in the same relative locations, too, so it’s possible to change lenses on set without having to move accessories such as follow focus. Each lens also has a nine-bladed iris, and a focus that rotates 240-degrees.
The lenses have been made from advanced glass to ensure unified colour characteristics, with the whole set of primes being carefully colour matched to avoid any issues with colour matching in post. On top of this, the new Sony primes are certified for 4K capture, while minimising chromatic aberration, geometric distortion, vignetting, and breathing, making them idea for capturing vfx shots with a clean key.
