Shutter
This setting automatically adjusts shutter speed to maintain a constant exposure while keeping
iris aperture constant. If you want to maintain a fixed depth of field, this is the setting to choose.
It’s worth mentioning that the subtle automatic adjustments of the shutter may have an effect
on motion blur. It’s also worth keeping an eye out for any flicker that may be introduced from
various light fixtures on indoor shoots. URSABroadcast G2’s auto iris feature is not available
when the ‘shutter’ auto exposure mode is selected.
Shutter + Iris
Maintains the correct exposure levels by adjusting the shutter, then the aperture. If the
maximum or minimum available shutter speed is reached and exposure still cannot be
maintained, URSA Broadcast G2 will begin adjusting the aperture to keep exposure constant.

NOTE To adjust your iris from the LCD touchscreen, your URSA Broadcast G2 must
befitted with a lens that supports changing aperture via the camera. If you are using a
B4 or PL lens connected via the broadcast 12 pin connector, make sure that the lens
iris switch on the handgrip is set to ‘A’ or ‘auto.’
Tapping the ‘iris’ indicator once brings up the iris menu along the bottom of your
URSABroadcast G2 touchscreen. You’ll see your current lens aperture at the far left of this
menu. You can change the aperture by tapping the left and right arrows on either side of the
current aperture, or moving the slider left or right.
