Great tip.

Hi all,

I am curious about the type of laser pointers you are refering to. I have one that I use for highlighting presentations but it produces a very small dot on the subject. I have tried using this with my new Fuji 3800 and the camera doesn't seem to "see" it. I have read some posts that describe pointers with different tips. This seems to be a different type of unit than I have. What are the typical uses of these and where can you get them?

Thanks,

Ken

The type we are talking about are sold in shops as a children's toy. They output a shape outline not a spot, usually selectable patterns. Kids buy them and pretend to be Batman or Robin, or some more recent cult character.

In UK there was concern about kids zapping peoples eyes out, so they brought the power down. I've seen them in holiday resorts in Spain.

I've used one of thouse to highlighting presentations at home with no light at all and it works perfectly. I supose at a distance greater than a few meters it will need a "bigger point"

Thanks for the information. I suppose the procedure is to point the laser, presee the shutter half way when the laser point or image is in the AF Box in the viewfinder, shut the laser and snap the picture. Does the AF warning disappear when the camera "sees" the laser?

Just be careful WHERE you use those laser pointers. In today's world where everybody is ready for a terrorist attack you could be mistaken for a sniper, especially if you have a BIG lens :shock:

Basically, the tip is to get a laser pointer with some custom tips. You can get tips that convert the pointer from just a small dot to a line--the farther away the subject that gets lasered, the longer the line. It's bright enough in nearly all cases to provide autofocus within 50 or 75 feet (provided you have a nice bright laser pointer).

Remember to use the line tip so that (1) it's large enough to focus on, (2) you can orient it horizontally or vertically depending on the focus point you're using. In point (2), there's a lot of dSLRs that have multiple focusing points, and usually the points off to the sides are especially good at detecting vertical lines and the high and low ones are good at detecting horizontal lines.
