You can use the HyM (hyper manual) function when your lens aperture ring is set to a position other than the "A" position.
镜头光圈环转离A位置后可使用HyM功能

You can use EV compensation in the M (manual) mode.
手动模式下可做曝光补偿

If you are using the auto bracketing mode and the camera automatically powers
down after a period of inactivity, the auto bracketing mode will not be
cancelled.
包围曝光后如机器自动节能关机, 包围模式不会自动取消

Note that turning off your camera normally will cancel the auto bracketing
mode. This enhancement only applies when the *istD engages its auto-power-off
function.

The file format and file system of the *istD are compatible with the EXIF 2.21
and the DCF 2.0 standards.

文件系统将和EXIF 2.21和DCF 2.0标准兼容

When you set [Color Space] in the *istD custom function menu to [Adobe RGB],
your TIFF and JPEG image file names will change from "IMGPxxxx" to "_IGPxxxx"
where "xxxx" is a 4 digit numeral.

当在色彩空间设置中改为Adobe RGB时, Tiff和Jpeg文件名前四字母会自动从IMGP改为_IGP

倦鸟:

DIY应该是可以的，但是不容意找准位置，也不容意弄得好看。

我印象不深，估计没有改变。

我希望有CF功能可以使某个点一直亮着，合焦时闪一下继续亮着，这样弥补了聚焦屏上没有刻对焦点带来的不便。

Lunatic : 对焦点的显示方式有没有改善？
