That putting a certain lens on a smaller crop sensor gives it extra
It is easy to erroneously think in our minds as photographers
#Camera crop factor full size
That lens would be "normal" on a full size sensorĬamera and would be a telephoto lens on the camera with the smaller Of using an 80 mm lens when using that same lens on a camera with a 1.6 Lens on a camera with a full size sensor would give you the same effect Look at the 2 highlighted spots in the chart above. What it really means is it shows the lens focal length that has the same angle of view as a full frame camera would give you. The chart below shows you how a certain lens "acts" when it's on a cropped sensor camera. This simple tool has a drop down selector where you can type in the exact dimensions of your camera's sensor and it will automatically calculate the number for you. The easiest way to calculate crop factor is to use a free online crop factor calculator. Depending on how much smaller the sensor size is than full, the focal length multiplier can be calculated. It's also referred to as a focal length multiplier, because you're getting the equivalent view that a longer lens (a narrower view) gives you.Īs a result – when you fit a lens to a camera with a smaller sensor the lens is often said to have a larger equivalent lens size. In other words, it crops part of the photograph that the lens is capable of including in your photo. The illustration above show you what would happen if you used the same lens on two different cameras-one camera with a full-frame sensor and with having a smaller-than-full-frame "crop" sensor.Ī "crop factor" means that your photograph would have a smaller field of view. The smaller rectangular area shows what the smaller "Crop" sensor camera will record on its sensor.
