Item description

Ideal for landscape and architecture
The compact Samyang 21/1.5 Video APS-C for mirrorless system cameras is ideally suited for creative landscape and architectural shots from extraordinary perspectives, but also for street and documentary shots. Even detailed close-up shots are possible thanks to a close-up limit of only about 30 cm. Thanks to the very high speed of T/1.5, the lens delivers optimum results even in low light. The lenses optimized for videography have a stepless aperture. The aperture ring and the focus ring are equipped with a gear rim and are therefore optimized for use with a follow focus device.

High quality optics
A particularly high-quality optical construction consisting of 8 multi-coated glass lenses achieves excellent imaging results. In addition, 3 aspherical lenses (ASP) ensure the best possible correction of chromatic aberrations. Lateral incident light and lens reflections are prevented by a lens hood, which can be removed if necessary. The lens is internally focusing, so the overall length of the optics does not change. Focusing is done manually and enables precise focusing.

Using an APS-C lens on a camera with full-frame sensor
Some lenses developed for cameras with APS-C sensors can also be used on cameras with full-format sensors (mainly by using an adapter). Due to the significantly smaller image circle of APS-C lenses, the sensor area outside the image circle is black. The usable area of the image photographed with a full format camera thus equals that of a camera with an APS-C sensor and is correspondingly smaller. Therefore, the images have to be trimmed during post processing. In the video field, this method requires framing in post-production. The use of APS-C lenses on full frame cameras is therefore possible, but not recommended.

Why the aperture is sometimes given in T
In photography, the abbreviation "f" is used for aperture (from "focal length"). The given value indicates the ratio between focal length and entrance pupil at the lens. In film and video, on the other hand, the abbreviation "T", which stands for "transmission", is used. This value is calculated from the aperture f and the loss of light in the individual lens. It indicates the net brightness of the image that hits the sensor. This makes it possible to change the lens when filming: As long as the "T-Stop" is selected the same for both, it is guaranteed that two shots filmed with different lenses of the same scene are equally bright. Thus, there are no jumps in brightness when they are edited together.
