Focus assist

The focus assist function can be switched on or off in the Operator Toolbox menu. This

function adds a motion effect in the viewfinder to objects in sharp focus. The FOC+

indicator in the viewfinder lights when this function is on.

Viewfinder zoom

The viewfinder zoom function is another feature that helps you focus. This function

enlarges the center of the viewfinder image. Choose one of the following buttons and the

way it operates (momentary or toggle) to control this function in the

Operator To olb ox

menu:

• The VTR button on the lens,

• The RET switch on a zoom control when a SuperXpander is used.

When the viewfinder zoom function is in use, the viewfinder markers are switched off to

improve the clarity of the display. The Zoom indicator in the viewfinder flashes when the

viewfinder zoom function is active.

Lens operation

Back focus adjustment

When you fit a lens to the camera you may need to adjust the back focus. Refer to the lens

manufacturer's instructions to find out how to do this. The

Lens menu allows you to choose

and, if necessary, adjust other parameters to suit your lens type and your personal

preferences.

CLASS

The Chromatic Lens Aberration and Sharpness Solution (CLASS) compensates for chromatic

aberration by using lens data. Most major lens manufacturers support this feature.

Make sure that the lens interface is set to Digital in the

Configuration > Lens > Lens Settings > Lens IF Type menu.

When a lens is attached to the camera for the first time, the camera reads the lens data at

startup. This is done only once and may take some time to finish. Reading the lens data is a

background process and does not influence normal camera operation.

Some lenses also require a manual calibration of the lens ring positions. If this is the case, a

message (“CLASS: Turn lens rings”) is briefly shown in the viewfinder. Turn both zoom and

focus ring all the way from one end to the other.

After startup when CLASS is active, a message (“CLASS: Active”) is shown in the viewfinder.

In the (very rare) occasion that lens aberration data becomes corrupted, a reset of the lens

data can be forced:



Go to the Configuration > Lens > Lens Settings > CLASS > Reset CLASS Data menu

and select Start.
