Kritz Cam Pro is an add-on for Blender that handles camera creation along with focus control and constraints. It lets you change focal lengths and F-Stops in a simple way, and includes easy camera focus and an easy camera focus constraint. The addon ships with 7 fixed focal lengths and 11 F-Stops, plus easy switching between navigation modes.
The interface includes a focal lengths pie menu and a Composition Guides menu. Shortcuts are built in: the Kritz Cam Pro menu opens with Shift + Home, and the focal lengths pie menu with Control + Home. Recent updates renewed the menu design and added Passepartout control on the menu, a scene lights random color generator, and Composition Guides on the menu.
Kritz Cam Pro is aimed at users who do not want to spend time creating cameras and setting constraints, and who want to make changes on the fly to F-Stops and focal lengths. It is a Dev Fund Contributor add-on, and documentation is provided. A demo video is also available.
