This illustration shows how a 35mm (full frame) sensor and an APS-C (crop) sensor capture different amounts of the same image circle projected by a 50mm focal length lens. For this reason, a 50mm lens on APS-C has an “effective focal length” of 80mm on full-frame since the angle...
Effective-focal-length calculations and measurements for a radial diffraction grating 来自 掌桥科研 喜欢 0 阅读量: 46 作者:JA Koch,S Cui,MA Mcneill 摘要: As the technology for manufacturing radial diffraction gratings improves, there will be increasing interest in using high-groove-density radial ...
Field of view vs focal length – everything you need to know December 18, 2024 Field of view and focal length are two of the most important lens parameters. As simple as they are, not many understand them thoroughly. Learn what they mean, how the two are related, and why it is im...
A plurality of additional lens systems are provided to optically adjust each camera lens as to its effective focal length, enabling the use of a uniform film platen in the camera. Additional lens systems of the same design may be used to adjust the focal length of each of the lenses of a...
