-Switching between picture-taking and playback
When you switch quickly between picture-taking and playback with the PowerShot G1, the lens does not retract. Since
the lens retraction time is eliminated, you can switch between picture-taking and playback instantly. Right after taking
pictures, you can playback the pictures on the monitor and delete the unwanted ones. Then you can go back to taking
pictures.
Note : The lens will not retract if the Main Dial is changed from camera mode to playback mode via the off position within 0.8
seconds.
-Continuous AF (in using LCD monitor only)
With the PowerShot G1, you can select either single AF (operates at SW1) or continuous AF (the default) for the AF
mode. In the continuous AF mode, autofocusing operates even when you are not pressing the shutter button.
The LCD monitor thus always displays a focused image which makes it easier to identify the subject on the monitor.
To respond to changes in the subject’s position and to enhance AF precision, the focusing information at SW1 is used and
the focusing is rescanned within a narrow range centering on SW1. This makes autofocusing more precise and faster than
in the single AF mode.
Note : AF mode is fixed to Single AF when LCD viewfinder is OFF.
-Switchable video output format (NTSC/PAL)
The PowerShot G1 provides the setting menu to set the video output format to either NTSC or PAL. This enables you to
playback the images on a TV monitor in various countries.
Note :
-For areas using SECAM (such as France), playback is possible in the PAL format. However, the image will be in black and white.
-The language options (five NTSC languages and ten PAL languages) remain the same regardless of a change of video format.

-Vari-angle LCD monitor
Like the PowerShot Pro70, the PowerShot G1 is
equipped with a vari-angle LCD monitor (1.8-inch)* .
The monitor can be rotated so you can shoot from
various angles.
Also, when the LCD monitor is rotated toward
the front (for self-shooting), the monitor displays
a mirror image so you can see yourself correctly.
* The PowerShot Pro70 uses a 2.0-inch monitor.
-New UI for easy-to-read controls
The PowerShot G1 has many features such as manual settings in addition to
Image Programmed Control Zone modes. To make camera operation easy
even with all these features, the PowerShot G1 has the Main Dial and Mode
Dial stacked together and an on-screen menu that does not have a deep
hierarchical structure. You can therefore quickly set the desired mode or
setting. The Main Dial below the Mode Dial provides the power OFF, cam-
era ON, playback, and PC mode settings. The Mode Dial is for setting seven
Image Programmed Control Zone modes, Auto, and four Creative Zone
modes. Also, frequently used features such as exposure compensation, the
macro function, etc., have their own buttons, and there is a Omni Selector
(which was well received on the PowerShot S10 and S20). The user interface is thereby quick and simple.
A large Display panel is provided to make it easy to check the camera’s status at a glance (refer to p.G19).
