i have a lazer pointer with different attachments....as i can not open the link can someone who has seen the link briefly tell me how it helps with the auto focus in low light?

Well, it helps in low or even no light because it provides a sharp line on which the camera can focus. Once it's focused, you turn off the laser pointer and take the picture. Obviously, in a low light situation you could use a time exposure or a flash, and in a no light situation you'd have to have flash.

This just provides you the capability to AF where you otherwise wouldn't be able to (and in some cases, couldn't reasonably focus manually either).

so simple :-)

I was thinking of using a laser that provides a read for distance to help with the manual focus of a range finder camera. Have not tried it out yet, but would like to know if anyone else has done this?

Reading this got me thinking...

I wonder how hard it would be to replace the AF assist lamp with the internals of a laser pointer? Considering the low power reqs of a laser, I don't think there would be a power problem. Anyone here ever worked with the interals of their digicam?

Idealy, I think the best situation would be to add the laser as an additional light in parellel w/the AF lamp and an on/off switch. Many cameras use the AF assist lamp as the red-eye reduction also, so you wouldn't want the laser flashing for each picture. Of course, this would mean drilling an additional hole in the body.

What do you think of this? Am I asking for trouble w/my camera?



Thanks,

Scott

I am not a camera expert, in fact, I am not even more than just beyond Point and Shoot, but I do solve many problems like this as part of my job. Before, I try to drill through what is most probably a very dense case, I would evaluate what connections are available outside of the camera. For instance, does the external flash connection get a prime signal when the shutter button is half-pressed? If, so I would piggy back off of that connector, otherwise, I would keep hunting that direction first.

Can you please post again how to use the laser pointer for taking picutres. The site posted in first post does not connect, for me at least. Thanks

I don't know about the other cameras but the Fuji S5100/S5500 FA light uses a four square pattern to create a contrasting image for the AF. Theres also a couple of dots and lines in the pattern. It's not enough to just shoot a dot or circle; there needs to be a contrast (light/dark) pattern for the AF.

If you get a laser, get one that has patterns like a star or rings with "crosshair". There needs to be close contrasting light/dark areas close together.
