content: $100.....maybe a little steep, but worth every penny to get some memorable shots of your child in a lead role of her last high school musical. I have done it in the years pass without an remote flash with the pictures turning out dark and blurry. Using it my S2IS set on TV, I set the shutter speed at about 1/60 with the ISO at100, I was able to stand in the 3rd row seats which put me about 40'-50' from center of stage. After seeing the results I wish I would of bought this flash couple years ago. And do keep couple of the CR123A batteries on hand.
