Hey guys,
Not sure if this should be in the mutimedia or other section? It is a camera so I decided to put it here :D. It is a Sony DSLR-A300 and has 10.2 megapixles I got it secondhand for $300, I can't tell you much else because I am a noob with camera stuff but it does have 2 different lenses one for distance and one for regular :) It takes great pictures so from now on I won't be using my crappy phone camera anymore lol. I can't take a picture of the camera cause it's the only one I have besides my phone but here are some pics I took with it :D

Have you tried using a mirror to take a picture of the camera? :D

Great pics though, seems to handle low light very well.

How to focus the camera on beams?
Normally I focus the image at the laser aperture unless I am emphasizing the beam exclusively but you can adjust how much of the beam is in focus with aperture.

If you set your camera into manual (M) or aperture priority mode (Av) you can adjust the aperture.

Why don't you try setting up a laser and your camera and testing out what higher aperture values do to an image vs. what smaller aperture values produce. Hint: aperture controls depth of field and exposure.

*A high aperture number (f/8 for example) means a narrow aperture.
A low aperture number (f/2.8 for example) means a wide aperture.

Here's a good website if you want some simple and easy to comprehend explanations and tips: Learn Photography Concepts
Here's a link to depth of field: http://www.cambridgeincolour.com/tutorials/depth-of-field.htm

Oop, missed that question.

Your focus looks fine to me. Focus the camera using manual focus until the beam is as thin as possible. It may look like it's breaking up into lines, but that's a good thing, as your camera LCD can't display the full resolution.

If the beam looks OK on your camera LCD, it's probably out of focus ;)
