How to choice a lens 如何选择镜头 Choosing a Lens At first glance this seems a simple task, but you will be faced with lots of options and questions. Choose a good supplier. You will be better off talking to suppliers that design their own lenses, even if you only need an off the ...

A lens mount is an interface between a camera and lens that allows the lens to be securely attached to the camera body while facilitating communication between the two for functions like autofocus and aperture control.Consequently, most lenses are only compatible with a specific type of camera. B...
It is a part of an imaging system that includes the camera’s image sensor, RAW converter (which may sharpen the image), and image processing pipeline. Hence, Measurements are relative. It’s difficult to determine an absolute number for the lens alone. But you can accurately compare lenses...
The workflow below describes how to check for any altitude errors in the Geospatial Video Log file and correct them if necessary. The goal is to determine the correct height of the drone, then edit the height values in a copy of the log file and reprocess the video, either by re-r...
The Science Behind the Lens Light and Optics When light passes through a lens, it bends or refracts. The angle and thickness of the lens determine how much the light bends. In a Fresnel lens, each concentric ring has a specific angle and thickness to ensure light rays converge at a singl...
Focal LengthTechnically speaking, a lens’sfocal length, represented in millimeters, is the distance between the rear element of the lens and the focal plane, where the parallel beams of light entering a lens converge to a point. This matters to you because the focal length determines the lens...
aan object in front of a converging lens is 4 times the size of its image.If the focal length of the lens is 15cm,how far from the lens is the object? 一个对象在一个会聚透镜前面是4倍它的图象的大小。如果透镜的焦距是15cm,多远从透镜是对象?[translate]...
You cannot measure a lens in isolation.It is a part of an imaging system that includes the camera’s image sensor,RAWconverter (which may sharpen the image), and image processing pipeline. Hence, Measurements are relative. It’s difficult to determine anabsolutenumber for the lens alone. But...
