Cubic – This is the distortion type used in some camera tracking programs like SynthEyes and Boujou. If you plan on using one of these programs, use this distortion type.
Lens file – An external .lens file is used to determine the distortion for the camera.
Texture – A displacement map from Nuke can be used to determine the camera distortion.

Distortion amount  – Specifies the distortion coefficient for the camera lens. A value of  0.0  means no distortion; positive values produce "barrel" distortion, while negative values produce "pillow" distortion. This parameter is available only when Quadratic or Cubic is selected as the Distortion type.  For more information, see the Distortion example below.

Lens file – The file used to calculate the camera distortion. This is only available when the Distortion type is set to  Lens file.

Distortion map – The texture used to determine the camera distortion. This is only available when the  Distortion type is set to Texture.

F-number – Determines the width of the camera aperture. For more information, see the Exposure Control: F-Stop (f-number) example below.

Horizontal/Vertical lens shift  – Values other than 0 tilt the lenses to simulate 2-point perspective.

Guess vertical lens shift – Click to automatically set the Vertical lens shift parameter to achieve 2-point perspective. 

Shutter speed – The shutter speed, in inverse seconds, for the still photographic camera. For example, a shutter speed of 1/30 of a second corresponds to a value of 30 for this parameter. For more information, see the Exposure Control: Shutter Speed (s^-1) example below.

Shutter angle – Shutter angle (in degrees) for the cinematic camera.

Shutter offset – Shutter offset (in degrees) for the cinematic camera.

Latency – CCD matrix latency, in seconds, for the video camera.

ISO – Determines the film power (i.e. sensitivity). Smaller values make the image darker, while larger values make it brighter. For more information, see the Exposure Control: Film Speed (ISO) example below.

Specify focus – This allows you to specify a focus distance different from the camera target distance.

Focus distance – Sets the focus distance of the camera.

Exposure color correction – Specifies how the F-number, Shutter speed, and Film speed (ISO) settings affect the image brightness. For more information, see Exposure, Field of View and Focus Distance example above.

No Exposure – Shutter speed, F-number and ISO settings do not affect the image brightness;
Physical Exposure – Image brightness is controlled by the Shutter speed, F-number and ISO;
Exposure Value (EV) – Uses the Exposure value to control image brightness. Grays out the ISO parameter and uses Shutter speed and F-number values only for Motion Blur and Depth of field respectively.

White balance – A color that can be used to alter the image output. Objects in the scene that have the specified color appear white in the image. Note that only the color hue is taken into consideration; the brightness of the color is ignored. For more information, see the White Balance example below.

Exposure value – Controls the exposure value when the Exposure Value (EV) option is selected. Higher values make the render darker, whereas lower values make the render brighter.

Enable vignetting effect – When this option is enabled, the optical vignetting effect of real-world cameras is simulated. For more information, see the Vignetting example below.  

Vignetting amount – Specifies the amount of the vignetting effect, where 0.0 is no vignetting and 1.0  is normal vignetting.

Enable Bokeh effects – Defines the shape of the camera aperture. When this option is disabled, a perfectly circular aperture is simulated. When  enabled, a polygonal aperture is simulated. This option has an effect when depth-of field is enabled.

Number of blades – Specifies the number of blades of the polygonal aperture.

Blades rotation (in radians) – Defines the rotation of the blades.

Center bias – Defines a bias shape for the bokeh effects. Positive values make the outer edge of the bokeh effects brighter; negative values make the center of the effect brighter.

Bokeh anisotropy – Values other than 0 stretch the bokeh effect horizontally or vertically to simulate anamorphic lenses. If you want the ratio of height to width of the bokeh to be k:1,  then the value for anisotropy should be sqrt(1/k)-1. For example, for anamorphic bokeh, which is 2.39:1, the anisotropy value should be -0.353. 

Enable Depth-of-field – Turns on depth of field sampling. For more information, see the Depth Of Field (DOF) example below.

Enable Motion blur – – Turns on motion blur sampling. Keep in mind that motion blur is not rendered with V-Ray IPR. For more informationa visual aid, see the Motion Blur (MB) example below.  

Aperture map – Specifies a texture to define the shape of the aperture.

Affects exposure – When enabled, the size and shape of the aperture specified in the Aperture map affects the exposure of the final image.

Cat's eye bokeh – Controls the strength of the optical vignetting, also known as "cat's eye" vignetting. This effect is due to the fact that the shape of the bokeh highlights resembles the shape of the aperture. As the distance to the optical axis increases, the bokeh highlights are progressively narrowed and begin to resemble the shape of a cat's eye. The larger the distance from the image center, the narrower the cat's eye becomes. Optical vignetting tends to be stronger in wide angle lenses and large aperture lenses, but the effect can be noticed with most photographic lenses.

Rolling shutter mode  – Specifies whether the rolling shutter effect is enabled and the direction of the shutter. The Rolling Shutter effect options are active only if the Motion Blur is enabled. For more information, see the Rolling shutter mode example.

Rolling shutter duration – The time for the shutter to pass through the image in 1/seconds.

Camera shader texture – Allows a V-Ray OSL texture to be attached to the physical camera. OSL textures allow additional options to be added to the camera such as blur, color and others. Note that this options is not supported when rendering in the Viewport IPR.
