Item description

Developed for videography and photography
With the Samyang 10/3.1 Video APS-C you are optimally equipped for video as well as photography without having to time-consuming convert your camera. The aperture can be infinitely adjusted, allowing you to smoothly compensate for changes in brightness. The aperture ring and focus ring are equipped with a gear rim and are therefore optimized for use with Follow Focus systems.

Ideal for landscape, architecture, art and nudes
The Samyang 10/3.1 Video APS-C with a focal length of 10 mm and a speed of T/3.1 is ideal for landscape and panorama shots thanks to its large image angle. This high-quality wide-angle lens is also ideal for architectural, art and nude photography. Focusing and aperture adjustment are done manually. The close-up limit is 24 cm. The image circle is only suitable for APS-C sensors and smaller!

Excellent image quality thanks to multi-coated lens surfaces and NCS Nano Coating
For excellent imaging performance, great emphasis was placed on optimum lens design. All 14 glass lenses are multi-coated, which prevents reflections and provides the image with more light. In addition, the coating provides better contrast and more brilliant colour rendering. The reduction of reflections is additionally supported by a nano coating. Two of the 14 lenses are aspherical, ensuring optimum correction of spherical aberrations. In addition, one lens is made of ED glass (extra low dispersion), which optimally corrects chromatic aberrations.

Very high quality workmanship
The metal housing is very robust and convinces through its elegant appearance. In addition to the high-quality optics, the removable lens hood, which prevents stray light and lens reflections from entering from the side, helps ensure optimum image results.

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.
