...

Field of view (FOV) in degrees. For rectangular images this is normally the FOV along the narrower image dimension.

fov (end)

Field of view (FOV) in degrees. Used to motion blur fast zooms. 0.0 means it is the same during the rendering

F-stop

Aperture size, controls depth of field blurriness. High values emulate a pinhole camera and depth of field is disabled.

Focal Length

The focal length of the camera in scene units measured from the camera lens. High F-stop values disable this.

Focal Distance

Distance to the focal plane where objects are in focus, measured in scene units from the camera to the object. High F-stop values disable this.

Tilt-Shift

tilt

Angle in degrees to tilt the lens. Makes the plane of focus non-parallel to the image plane. Has no effect unless depth of field is enabled. Positive tilts up, bringing the focus in the top of the image closer and pushing the focus in the bottom further. Negative does the reverse.

...

Roll the lens clockwise. If the lens tilt is non-zero this can be used to rotate the plane of focus around the image center.

Focus 1, 2, and 3

These point coordinates define an arbitrary plane (3 points is a triangle). This is used as the arbitrary focal plane. Note that a plane very oblique to the camera may fail to render.

shiftX

Shift the lens horizontally. This can be used to correct for perspective distortion. Positive values shift towards the right.

...

Exposure duration. Zero means an ideal rolling shutter where each line is exposed instantaneously when read. The default, one, is equivalent to a global shutter where all lines are exposed and read at the same time.

Advanced

Detail Bias

Higher values shift texture mipmaps and dicing to coarser levels, or less detail. Negative increase details for both. Adjust in small increments.
