Focal length magnification

WebJan 25, 2024 · For example, the effective focal length of a lens with a focal length of 50mm on a crop sensor (let's say it's an APS-C sensor) will be 50 × 1.53 = 76.5 mm. However, this magnification effect is due to the image being cropped by the smaller sensor. While you will gain in magnification, you will lose in terms of image quality. WebThe resulting magnification is simply the ratio of the near-point distance to the focal length of the magnifying lens, so a lens with a shorter focal length gives a stronger magnification. Although this magnification is smaller by 1 than the magnification obtained with the image at the near point, it provides for the most comfortable viewing ...
