Open Access Mixing and matching sensor format with lens coverage

The 36x24mm 135 film format was most popular for highend consumer cameras for decades, but the difficulty of making large sensors made smaller formats more common in digital cameras. The result is a variety of sensor formats – and lenses designed to cover each. However, mirrorless bodies allow mounting lenses designed for various non-native formats. One would expect lenses to work best using the sensors they were designed for, but there are many potentially good reasons to use lenses designed for one format on a sensor of another format. This paper explores how lens behavior changes as lenses are used on non-native sensor formats, either directly or with the addition of optical elements that have the side-effect of adjusting coverage: rear-mounted focal reducers and tele-converters.

  • For more than 30 years, the Electronic Imaging Symposium has been serving those in the broad community - from academia and industry - who work on imaging science and digital technologies. The breadth of the Symposium covers the entire imaging science ecosystem, from capture (sensors, camera) through image processing (image quality, color and appearance) to how we and our surrogate machines see and interpret images. Applications covered include augmented reality, autonomous vehicles, machine vision, data analysis, digital and mobile photography, security, virtual reality, and human vision. IS&T began sole sponsorship of the meeting in 2016. All papers presented at EIs 20+ conferences are open access.

    Please note: For purposes of its Digital Library content, IS&T defines Open Access as papers that will be downloadable in their entirety for free in perpetuity. Copyright restrictions on papers vary; see individual paper for details.
