Designed for video use, especially mobile use on drones and gimbals, are the new, compact Samyang V-AF full-frame lenses, which, however, will only be released for the Sony FE mount. They offer autofocus - Samyang somewhat full-bodiedly touts them as the first AF cine lenses - as well as a few other special features.
Samyang V-AF lens series
For example, they feature tally lights that signal a shot in progress, as well as a robust front mount with electronic contacts. This is supposed to be intended for upcoming accessories, but Samyang does not reveal which ones yet. We would spontaneously think of a variable ND filter, for example, which would be quite useful for flight shots.
Samyang V-AF 75mm T1.9 FE
The five fixed focal lengths 20mm, 24mm, 35mm, 45mm and 75mm - all with a T1.9 - feature a uniform design with a 72.2mm diameter by a 72.1mm length, and the weight is 280g throughout. The center of gravity of all lenses is also said to be the same, so they can be changed without rebalancing in a gimbal setup.
Autofocus is driven by a linear STM AF motor, and in manual (linear) mode the rotation angle is 300°. There is only one lens ring, its function can be adjusted via a custom switch (focus/aperture). A focus hold button is present. Focus breathing seems to occur, Samyang cites values between 0.7 and 11.7% depending on the focal length.
The aperture is composed of 9 blades. The V-AF range is said to support resolutions up to 8K and offer consistent color reproduction. The lenses are weather sealed.
The first focal length to appear is the 75mm T1.9 FE in Q3/2002, followed by the 35mm and 24mm in Q4. Much later, the last two lenses will be released, the 45mm in Q2/2023 and the 20mm in Q4/2023. It is not yet known what the Samyang V-AF series will cost.
