Focal Length Tweaker earns its place in the Blender extensions library for a narrow, practical job: changing viewport and camera focal length by mouse, with a precision mode and remappable keymaps. Version 1.0.2 focused on viewport overlays displaying only on the active viewport.
Focal Length Tweaker is an add-on for Blender by 1P2D that controls viewport and camera focal length with your mouse. You drag to change focal length, with the default keymap set to CTRL+ALT+MMB, which can be changed in the add-on settings or Blender's main keymap menu.
A Precision Mode is available by holding the Shift key for finer accuracy, provided your keymap does not already include Shift. You can also set the mouse drag direction to horizontal or vertical. A CTRL+ALT+MMB double click switches between orthographic and perspective views.
Focal Length Tweaker is compatible with Blender 4.2 LTS and newer and requires no special permissions. Version 1.0.2 changed viewport overlays so they display only on the active viewport. The add-on is distributed under the GNU General Public License v3.0 or later.
Focal Length Tweaker is best for blender users who want mouse-driven control over viewport and camera focal length.
Focal Length Tweaker is completely free to download and use.
Focal Length Tweaker is compatible with Blender 4.2 LTS and newer, so recent Blender releases are covered. It's currently at version 1.0.2, published in July 2025, and the download weighs 9.9 KB. The add-on requests no special permissions in Blender. If you're on a Blender build older than 4.2 LTS, you'll need to update Blender first before the add-on will run as intended.
Focal Length Tweaker maps to CTRL+ALT+MMB by default for adjusting focal length, and you can change this through the add-on settings or Blender's main keymap menu. The same CTRL+ALT+MMB with a double click switches between orthographic and perspective views. A Precision Mode is available by holding Shift for finer accuracy, though your keymap must not already include the Shift key for it to work.
