Tamron Is Working On 28-75mm And 28-80mm Zooms For Drones
Lens manufacturer Tamron is working behind the scenes on two zoom lenses that are especially suitable for use in combination with drones and gimbals. These are 28-75mm f/4 and 28-80mm f/4.5 zoom lenses with a compact form factor and minimal shifting of the center of gravity when zooming. This is according to a patent application filed by the company.
Fixed center of gravity
According to Tamron, there is a growing need for compact, high-quality digital cameras. This also leads to an increasing demand for compact but high-quality lenses. And because cameras are increasingly mounted on gimbals, it is important that the center of gravity does not shift during zooming. A gimbal only works well if the center of gravity of the camera plus optics is perfectly aligned.
The patent application proposes a new optical design that entails a ‘minimal’ balance shift during zooming. It would be small enough not to negatively affect the operation of a gimbal. Two lenses are further…
