MOTION DV LENS

I. What is a Motion DV Lens?

‌Motion DV Lens‌ is a special camera lens designed specifically for handling high-intensity sports scenes. It differs fundamentally in design and performance from the lenses of common mobile phones or ordinary cameras.

You can think of it as an eye that was created for "vitality":

 -Common camera lenses: Like human eyes, they need to constantly zoom and focus to see objects at different distances. The focus is on image quality and flexibility.

 -Motion DV lenses: More like the eyes of a fish, they have an extremely wide fixed viewing angle and almost no need for focusing. Everything from near to far can be clearly captured. The focus is on being broad, stable and durable.

II. Main features.

Super wide-angle fixed focus：

 -Wide-angle: Usually has a very wide field of view (such as 170°), similar to the "fish-eye" effect, which can capture as much of the scene as possible and is very suitable for shooting first-person perspectives (such as helmets, chests), without missing key scenes due to arm movement.

 - Fixed focal length: The lens focal length is fixed and does not provide optical zoom functionality. This is because zooming mechanisms are complex and fragile and are not suitable for motion scenes. Motion DV achieves a similar effect through "electronic zoom" (cropping the image), but at the expense of image quality.

Strong anti-shake performance

 -This is the essence of the sports DV camera lens. It usually works in conjunction with the electronic image stabilization (EIS) or mechanical image stabilization system inside the camera. By quickly sensing and compensating for shaking, it can counteract the jitter caused by intense movements such as running, cycling, and skiing, and output a stable and smooth picture.

‌Stability and Protection‌

 -The lens elements are usually made of very hard materials (such as Corning Gorilla Glass) to prevent scratches.

 -The entire camera (including the lens) often has features such as water resistance, dust resistance, shock resistance, and low-temperature resistance, and can cope with various harsh environments without the need for an additional protective case.

Focal range design

By adopting the "super focal length" design, objects ranging from several centimeters to infinity can remain relatively clear, eliminating the need for focusing and ensuring that there will be no blurring due to focusing errors during rapid movement.

III. The Core Difference from Ordinary DV/Camera Lenses

Summary

In simple terms, the motion DV lens is a specialized lens designed for movement. It sacrifices the flexibility of zooming and focusing in exchange for an extremely wide viewing angle, superior stability, and robust durability. It is specifically used to reliably capture clear, stable, and immersive first-person footage in high-speed, bumpy, and harsh environments.

Its most common form of application is various‌ action cameras‌, which are widely used to record scenes in outdoor activities such as skiing, diving, cycling, skydiving, hiking, fishing, etc., as well as in daily life.
