This means that a 50mm lens on an APS-C sensor has the same field of view as a 75mm lens on a full-frame camera. To determine the effective focal length, you would multiply the focal length by the crop factor.įor example, if you are shooting with a 50mm on a Nikon APS-C sensor, the effective focal length is 75mm. The effective focal length gives you the actual focal length of the lens on your sensor. To determine the real field of view, you need to calculate your effective focal length. The crop-factor on an APS-C means that the focal length of your lens is not an accurate measure of the field of view you are shooting in. The crop factor gives you a narrower field of view for the same focal length than a full-frame sensor would.ĪPS-C sensors have a crop factor of 1.5x or 1.6x, while full-frame sensors have no crop factor. One of the biggest differences between full-frame sensors and APS-C sensors is the crop factor, as shown in the image above. There are a few things to consider when choosing lenses for full-frame and APS-C sensors. Overall, by going with an APS-C camera, you can save at least 1 inch in size and over ½ a pound in weight. The only exception to this is mirrorless cameras.įor example, the Nikon D7500 APS-C camera weighs about 1.6 pounds while the full-frame alternative the Nikon D850 weighs about 2.2 pounds.Īnd if we compare the Nikon D7500 and the D850, the D7500 is ½ inch shorter and ½ inch narrower than the D850. One of the major disadvantages of full-frame cameras is that they are typically larger and heavier than APS-C cameras. That means there will be less visible noise at all ISO values on full-frame cameras than APS-C cameras. Since full-frame cameras typically have larger pixels, they collect more light and produce a higher SNR. The higher the SNR, the less apparent noise will be when using a high ISO. SNR is the ratio between the light and noise gathered in the same pixel.įor example, if a pixel collects ten photons of light and one particle of noise, it will have an SNR of 10:1. While each pixel on a sensor generates the same amount of noise, they record different amounts of light. The sensors’ larger surface area allows them to collect more light. This is because they have more than 2x larger sensors than APS-C cameras. There are two important factors that determine how a sensor performs in low light:įull-frame cameras tend to perform better in low light conditions than APS-C cameras. The only way for an APS-C camera such as Sony A6400 to have the same amount of pixels as Sony A7is to use smaller pixels (24.2MP). The Sony A7 full-frame camera, for example, has 24.3MP.įor an APS-C camera to have the same pixel size, it would need to have 2.3x fewer pixels than a full-frame camera.īut, while this would improve image noise, it would reduce the resolution and detail in an image. So full-frame cameras tend to produce less apparent noise than an APS-C camera. If you crop your images (t he additional resolution will the quality of your image even after you crop your image.)Īnd full-frame cameras typically have larger pixels than APS-C cameras.Having a higher resolution is beneficial on two occasions: Image QualityĬamera sensors influence image quality in two ways:īoth APS-C cameras and full-frame cameras deliver high-quality images.īut full-frame cameras offer a higher resolution because their larger sensors allow for more pixels.
