Hi all, I've used a regular point and shoot digital camera all this time and have decided I want to get involved in more serious photography. I'm intrigued with infrared photography, I enjoy macro and long shots. I definitely want a cam with a minimum of a 8x optical zoom. I have a list of cams that I am considering and would love your input on which one I should get based on the above. 1. Panasonic Lumix DMC-FZ20 or FZ30 2. Panasonic LUMIX DMC-FZ7 or FZ5 3. Nikon Coolpix 8700 or 5700 4. Canon PowerShot S2 IS 5. Sony DSC-H1 or H2 or H3 I don't mind suggestions on discontinued models, I think I would be able to track them down on eBay. What IR filters would you recommend for the Panasonic cams, and the others too? I've read up on the IR test (pointing a TV remote at the cam), but have no idea which IR filters would be perfect for the cams mentioned above. I appreciateany advice and thank you all in advance.
