Power is not supplied to the product via a micro USB cable when the product is connected to a computer, etc.

If you use the supplied AC Adaptor, power will be supplied even when [Off] is selected.

---------------------

TC/UB Settings

The time code (TC) and the user bit (UB) information can be recorded as data attached to movies.

---------------------

AF Illuminator (still image)

The AF illuminator supplies fill light to focus more easily on a subject in dark surroundings.

In the time between pressing the shutter button halfway down and locking the focus, the AF illuminator lights up to allow the camera to focus easily.

You cannot use [AF Illuminator] in the following situations:

When the shooting mode is [Movie] or [High Frame Rate].

Sweep Panorama
When [ Focus Mode] is set to [Continuous AF] or [Automatic AF] and the subject is moving (when the focus indicator or lights up).

When [Focus Magnifier] is activated.

When [Scene Selection] is set to the following modes:

    [Landscape]
    [Sports Action]
    [Night Scene]
    [Pet]
    [Fireworks]

---------------------

Center Lock-on AF

When you press the center of the control wheel, the camera detects the subject positioned in the center of the screen and continues to track the subject.

Hint

If you assign the [Focus Standard] function to the key of your choice,

you can activate [Center Lock-on AF] or detect a subject again by pressing the key when [Focus Area] is set to [Wide] or [Center].

---------------------

Pre-AF (still image)

The product automatically adjusts focus before you press the shutter button halfway down.

During focusing operations, the screen may shake.

---------------------

ND Filter

If you use an ND filter, the amount of light entering the camera is reduced.

You can slow down the shutter speed and decrease the aperture value for a better exposure.

Menu item details

Auto:

    Automatically turns on the ND filter based on the shooting mode and brightness.

On:

    Always uses [ND Filter].

Off:

    Disables the [ND Filter] function.

Hint

    When the ND filter is activated, the icon is displayed on the bottom of the screen.

---------------------

High ISO NR

When shooting with high ISO sensitivity,

the product reduces noise that becomes more noticeable when the product sensitivity is high.

  • Normal
  • Low
  • Off

---------------------

Phase Detect. Area

On:

Displays the Phase Detection AF area.

Off:

Does not display the Phase Detection AF area.

When recording movies, the Phase Detection AF area will not be displayed.

---------------------

Memory (Camera Settings1/Camera Settings2)

Allows you to register up to 3 often-used modes or product settings to the product and

up to 4 (M1 through M4) to the memory card. You can recall the settings using just the mode dial.

M1 through M4 can be selected only when a memory card is inserted into the product.

Settings registered to a memory card using another camera of the same model name can be recalled with this camera.

---------------------

Focus Mode

(Automatic AF):

[Single-shot AF] and [Continuous AF] are switched according to the movement of the subject.

When the shutter button is pressed halfway down, the product locks the focus when it determines that the subject is motionless,

or continues to focus when the subject is in motion.

(DMF):

You can make fine adjustments manually after performing auto focusing,

letting you focus on a subject more quickly than when using the manual focus from the beginning.

This is convenient in situations such as macro shooting.

---------------------

Drive Mode

Cont. Bracket:

Shoots images while holding the shutter button down, each with different degrees of exposure.

Single Bracket:

Shoots a specified number of images, one by one, each with a different degrees of exposure.

DRO Bracket:

Shoots a total of three images, each at a different degree of D-Range Optimizer.

---------------------

Long Exposure NR (still image)

When you set the shutter speed to 1/3 second(s) or longer (long exposure shooting),

noise reduction is turned on for the duration that the shutter is open.

With the function turned on, the grainy noise typical of long exposures is reduced.

[Long Exposure NR] is not available when

  • [Shutter Type] is set to [Electronic Shut.].

[Long Exposure NR] cannot be set to [Off] in the following shooting modes:

  • [Intelligent Auto]
  • [Superior Auto]
  • [Scene Selection]

---------------------

Metering Mode

Entire Screen Avg.:

Measures the average brightness of the entire screen.

Highlight:

Measures the brightness while emphasizing the highlighted area on the screen.

This mode is suitable for shooting the subject while avoiding overexposure.

這大概要追溯到二十世紀五、六十年代電子成像技術剛開始的時代吧。那時早期的電視攝像機使用的感光元件是真空管(現在常見的CCD和CMOS傳感器)。真空管的外面是有個玻璃罩子的,真空管外徑是把玻璃厚度也算進去的,玻璃管當然是不能用於成像的,外徑1英吋的真空管,實際成像區域只有16mm左右,於是16mm就成了電子攝像照相行業一個約定俗成的度量單位。

所以現在數碼成像元件中提到英吋這個單位,都不能按工業標準的1英吋=25.4mm來計算,而要按1英吋=16mm來計算。

其數值稱為OF值,單位為英吋。因此CCD尺寸的標準OF值計算方法是其實際對角線長度
