SLH-C220是CANON設計給數位相機搭配使用的輕巧化閃光燈，是以CANON
220EX閃光燈為基礎的潛水用閃光燈。直接同步,擁有E-TTL自動閃光控制系統(E-TTL預閃測試,AF輔助光源)的插腳式閃光燈
·對應全新E-TTL自動評價系統的小型閃光燈。
The
SLH-C220 is a small and lightweight underwater housing designed exclusively for
the Canon SPEEDLITE 220EX Flash Unit. Operation is effortless. All you need do
is press the shutter release. The housed flash does the rest. When dedicated to
a compatible Sea & Sea housing for a Canon digital SLR camera, the flash
automatically provides natural-looking balanced flash exposures. It delivers
perfect illumination for macro imaging when used independently and is
well-suited for wide angle when used in conjunction with a Sea & Sea slave
strobe. This is a high-performance underwater lighting system even first-time
shooters will master with ease.

About E-TTL Automatic Light Control
E-TTL automatic flash exposure control was developed by Canon. Canon defines it
as an evaluative pre-stored flash control system. When in E-TTL operation, flash
exposure is measured and controlled by the camera in combination with CanonÕs
AIM system. The E-TTL automatic light control system measures the light
intensity from the pre-flash, ambient light level, including very bright areas
in the image area, as well as subject position and reflectivity are all
instantly analyzed. The system then calculates a correct flash exposure for a
balanced, properly illuminated image.
*Due to the absorption of light underwater, the intensity of the pre-flash may
be weaker than that of the main flash and may mislead the metering system.
Errors in E-TTL function may occur. Adjustments in subject position, camera
angle, and subject-to-flash distance will be necessary.
*5-pin sync cord N (17100) is not usable with the SLR-C220.
