I have bought me a "new" (used) camera for special photos like infrared pictures. It's an 8 year old Sony F828.
It's a camera with "nightshot-function", so you can use it with a IR-filter and shooting pictures without a tripod.
I have bought two IR-filters, a 720nm and a 850nm. Next month I will buy a 950nm, because for more "Drama...Baby!".
The camera is a bit noisy, but hey...who cares.
