New Camera Lens beam shot test

[Aardvark777]

Well I enjoy photography, and decided my 18mm - 105mm F3.5 lens wasn't cutting the mustard at night, and I wanted something fast and wide angle. So I bought a Samyang (Rokinon) 24mm, F1.4 manual lens. Here are a few test shots from last night. Camera is a Nikon D90.

The laser is a cheap and cheerful 405nm at around 25mW-50mW in an 850 host, luckily it shows up very brightly with such a wide aperture, I was just curious to see how the Samyang lens would depict 405nm light. The images aren't my best, but it was dark out last night and it's my first time using the lens, so I'll improve my images soon enough.

Pictures were all taken at F1.4, ISO 2000, 10 seconds.

:thanks:

That are some nice pics you got there. Is it that much easier to see 405nm on camera than in person?

Am i the only one that has a hard time getting 405nm to look right on a phote ?

Thank you gozert! Smeerworst umm maybe, have you checked your white balance? May well depend on how the camera is set up, also if you've got a UV filter on your lens it'll always show up as pale blue when it should appear pink.

1W of 405nm looks like this with a long exposure

The longer you expose for the more vivid a laser becomes. I just got a 7W (Yes 7 Watt) hand held 445nm from Sci Fi Lasers, so that thing will require a very short exposure. Divergence I think is mindblowingly high but it sure puts a huge grin on my face, and it ignites wood isntantly. I can literally bar code a cloud with it and watch as the cloud changes colour :eg: so needless to say this month I'll be photographing and reviewing it.

older cameras seem to do it better if you adjust lighting settings.
