Canon HF-DC1 High Power Flash for Canon Powershot Digital Cameras

I was disappointed with this product and returned it to Amazon. The service from Amazon was excellent.

I take many photographs in a high school gym. My Power Shot A620 takes great pictures but the built in flash just doesn't have enough umpff for those longer shots. The[ASIN:B0007MGFI2 Canon HF-DC1 High Power Flash for Canon Powershot Digital Cameras]gives me the option of three settings of flash level that are more than enough to give me the shots I was previously missing. I highly reccomend this slave flash to those who own the Canon Power Shot 620. You won't be disappointed.

It is truly a HIGH-POWER flash unit. It is uniquely compact and utilizes a special technology which eliminates the need for an electrical connection between the flash unit and the camera. It automatically senses the output of the built-in camera and that sensing activates the HF-DC1 unit. I am thrilled with it.

I have used the Canon HF-DC1 High Power Flash several times under different lighting conditions and various subject distances. The unit does work well to improve the flash range of my SD550. The instructions were not that great. They tell you how to work and adjust the unit power level, but like every thing else in photo picture taking experience counts. Before you use this unit for a serious photo shoot take a few dozen trial shot to get use to it's capibility. I found that after using the flash for some distant shoots you have to remember to turn it off again when getting closer to a subject otherwise you get over exposures. As far as redeye goes I did not notice much changes. The unit is a slave and is activated by the cameras built in flash. Since the cameras built in flash is still close to the lense the incidents of redeye looked about the same to me.

WILL IMPROVE PICTURES WHERE THE BUILT IN FAILS. LIKE AMERICAN EXPRESS, BETTER NOT LEAVE HOME WITHOUT IT!. I ATTACHED MINE PERMANENTLY, SUGGEST YOU DO THE SAME. IT IS THERE WHEN YOU NEED IT! KEEP A SPARE BATTERY, YOU NEVER KNOW, LIKE A PACEMAKER BATTERY, YOU SNOOZE-YOU LOOSE!
