2021年1月18日 · The FOV for a 50mm lens would be 39.6 degrees horizontally and 27.0 degrees vertically. Diagonally, the FOV is 46.8 degrees. For a 55mm lens on a APS-C/DX sensor format body, the field of view would thus be 24.0 degrees horizontally, 16.1 degrees vertically and 28.7 degrees diagonally.

2024年1月25日 · 视场角是以光学仪器的镜头为顶点，以被测目标的物像可通过镜头看到的最大范围的两条边缘构成的夹角，称为 视场角（Field of View, FOV）。 在机器视觉中，视场是在相机成像仪上捕获的检测区域，镜头焦距和图像传感…

2024年4月12日 · Here’s a calculator for the angles of view from lenses on digital camera sensors, as well as angle of view charts for common focal lengths. And I’ve also included an explanation of why the diagonal angle of view matters more than you might think. I MAY get commissions for purchases made through links in this post.

What is the FOV of a 24mm lens? This will vary depending on the size of your camera sensor, but in general, the field of view of a 24mm lens will be somewhere around 84 degrees for full-frames, and 61 degrees for crop sensors.

2024年1月5日 · Fov指的是相机视场(Field of View)张角，用来描述拍摄的范围。 Focal Length则是焦距，指的是成像元件的光学中心到成像平面的距离。 Sensor则指的是相机的感光元件，也就是像平面所在的位置。

2022年5月8日 · FOV的全称是Field of View (视场角），它表示相机或者人眼可以接收或者显示的影像的角度范围。由于相机的成像原理，一般都会有视场角的限制。如下图所示当相机的CCD或CMOS传感器的成像平面W一定时，FOV由焦距f决定，当焦距越大时，看的越远 但是FOV就会

虽然可以代入36mm与24mm而分别计算水平视角或垂直视角，但如果没有特别说明，我们通常以最大视角为准，即代入对焦线长度43.27mm。 计算实例 50mm的焦距在135相机（底片对角长度约43.27mm）上的视角：

Field of View is an angle which depends on the focal length and sensor size, but the calculator also computes dimensional Field of View sizes (width, height, or diagonal fields) at some specific distance, like at the subject distance, and another, like at a background distance.

2018年2月12日 · For example, the Nikon 24mm f/1.4G lens has a maximum angle of view of 84°, while Nikon 300mm f/2.8G telephoto lens has a maximum angle of view of only 8°10′ when used on film or full-frame cameras. Take a look at the following illustration:

视场角 （Field of View，简称FOV）在光学工程中又称为视场，是指光学仪器（如相机 、望远镜等）能够观测到的空间范围的大小。它决定了光学仪器的视野范围，并以角度来表示。
