Laser pointer as AF assist beam.

Hi all,

I have bought a green laser pointer purely out of curiosity the other day. I came back home and was experimenting with it. Then I thought of the difficulties I face with autofocus in low light or on an evenly colored object, like when I try to shoot a whilte paper for white balance. I just took out my camera, it was quite dark then, and pointed the dot to a wall, sure enough, the camera acquired focus in a split second without any hunting. I suggest you use red laser because it's less powerful than green laser and less harmful. Green laser is some sixty times powerful than red, so it's likely dangerous too. A red laser pointer is hence safe, and costs around ten percent of the green one.

I hope this information was helpful to you all. Please take care not to shine laser directly into eye or even to skin, and not to the lens, to be on the safe side.

You can also draw pictures or write words on a wall in a dark room, keeping the shutter open in bulb mode and wrting with the laser pointer! I shall upload some pictures soon.

Enjoy!

Arun.
