F値（エフち、英: F-number）とは、レンズの焦点距離を有効口径で割った値であり、レンズの明るさを示す指標として用いられる。F値が小さいほどレンズは明るく（=レンズを通る光量が多い）、シャッター速度を速くできる。 F値のFとは「焦点の」を意味する"focal"から来ている。Fの後に数字を続けて（例：F2）表記する。なお、レンズの有効口径を用いて明るさを表現するこ …

WebAn f/0.9 lens must allow 1.5 more stops (more than 2x as much light) than an f/1.4 lens, and the physical size of the aperture to achieve that often requires a larger lens barrel diameter. Increasing the barrel diameter requires, at the very least, a larger front element, which can quickly add to the cost of a lens. WebTo do this we will first need to use the equation below to relate the image height h, focal length f and the half field of view Θ. This equation can be derived using simple geometry …
