F stop equation
Most modern lenses use a standard f-stop scale, which is an approximately geometric sequence of numbers that corresponds to the sequence of the powers of the square root of 2: f /1, f /1.4, f /2, f /2.8, f /4, f /5.6, f /8, f /11, f /16, f /22, f /32, f /45, f /64, f /90, f /128, etc. Each element in the sequence is one stop … See more In optics, the f-number of an optical system such as a camera lens is the ratio of the system's focal length to the diameter of the entrance pupil ("clear aperture"). It is also known as the focal ratio, f-ratio, or f-stop, and is very … See more The word stop is sometimes confusing due to its multiple meanings. A stop can be a physical object: an opaque part of an optical system that blocks certain rays. The See more Computing the f-number of the human eye involves computing the physical aperture and focal length of the eye. The pupil can be as large as 6–7 … See more The f-number accurately describes the light-gathering ability of a lens only for objects an infinite distance away. This limitation is typically ignored in photography, where f-number is often used regardless of the distance to the object. In See more The f-number N is given by: where $${\displaystyle f}$$ is the focal length, and $${\displaystyle D}$$ is the diameter of the … See more Depth of field increases with f-number, as illustrated in the image here. This means that photographs taken with a low f-number (large aperture) will tend to have subjects at one … See more The camera equation, or G#, is the ratio of the radiance reaching the camera sensor to the irradiance on the focal plane of the camera lens: where τ is the … See more WebThis is described by the equation below: \lvert \vec {F_ {f,s}} \lvert \leq \mu_s \lvert \vec {F_N} \lvert ∣F f,s ∣≤μs∣F N ∣ Kinetic friction Once an object begins to slide, kinetic friction …

Just because a lens has a similar f-stop doesn’t mean it lets in the same amount of light. For example a 50mm f/1.4 lens from Canon will probably let in a different amount of light compared to a 50mm f/1.4 from Sigma.
