Fun with aspheric lens... beam shots

[KingGlamis]

Kind of bored tonight, so I thought I would see what happened when I held an aspheric lens in front of a couple of different lights.

First off, for comparison sake, is my WF501D without the aspheric lens. Distance to the wall is 12 feet.

These next few are with the lens held slightly in front of the lens of the WF, and a couple are with the aspheric lens backwards (which didn't really change the outcome much).

This one almost matches the original beam, but is with the aspheric lens at just the right distance to produce a decent beam.

These next three are a cheapo 12 LED light that I have, shining through the aspheric lens. It looked really wierd in person.

Just having fun...

thats a bit scary...it made me think of "20,000 leagues under the sea" [old movie, the octopus part]

That multi LED setup might make a good cheap effect for the next dance I DJ!

Especially if you could get it to rotate or at least sweep left to right in the room.

You should see this post by a guy about going outside to show beam shots, not white wall shots. He had it right on.

are you referring to the one who modded his tiki-torch into a flashlight?

Ha ha, very funny. Some experiments will only work on a white wall. But you got me, breaking my own rules.

Yeah, the wacky multi-led effect wouldn't have shown up too well on a tree, but I bet it looks weird there as well.

I took these photos after getting my first aspheric lens a few weeks ago. I was using a 3D Maglite with a Cree Q2 LED. I believe it is a 50 mm x 35 mm lens. The rocks are about 40-50 feet from the light.

ASA 400, F 6.3, 15 seconds.

ASA 400, F 8.0, 10 seconds. Light on top of camera.
