Resolve Optics has developed an iPhone application that simplifies lens field of view (FOV) calculations.
Available in two versions - the FOV Calc App allows users to quickly work out what focal length lens you require or to calculate the field-of-view provided by a lens of a given focal length at a known distance or infinity.
FOV Calc Lite is a free version of the App with 8 commonly used sensor formats pre-installed.
The full version of the App - FOV Calc has the 8 preinstalled formats but also provides the option of editing, adding, deleting and saving sensor formats, enabling you to build your own sensor format database.
Both versions of the Resolve Optics field-of-view calculator are now available to download from the Apple iTunes Store.
