Additional functions provided by

Some items in the Custom menu will be modified if you upgrade the camera. For details,
see “Custom menu” (page 5).
A [Release w/oLens] item has been added
You can release the shutter even when no lens is mounted on the camera.
The range of the exposure compensation has been expanded
The range of the exposure compensation is expanded to ±5 EV (Before the update:
±3 EV).
An additional setting of the exposure step for the bracket shooting
has been added
The following setting has been added to the continuous bracket and single bracket
shooting functions: The exposure has been shifted by 3.0 EV and the camera shoots three
images (Before the update: Up to 2.0 EV). [3.0EV3] is indicated when this is selected.
The AF function has been improved
The speed and performance of autofocus have been improved. A noticeable result will be
acquired when some telescope lenses are used. However, this depends on the lens
mounted on the camera or the condition under which the subject shot.
If you upgrade the camera, [Release w/oLens] is added in the Custom menu (page 5).
You can set whether to release the shutter or not when no lens is mounted on the camera.
When you attach the camera to an astronomical telescope, for example, select [Enable]
so the shutter can be released.
• Correct metering cannot be achieved when you use lenses that do not provide a lens contact, such as the
lens of an astronomical telescope. In such cases, adjust the exposure manually by checking it on the
recorded image.
• When the exposure mode is set to “M,” the shutter release is controled by the setting of this item.
