I HAVE A PANASONIC DMC-FZ20K AND WOULD LIKE TO KNOW WHAT IR FILTER WOULD FIT IT AND THREAD SIZE. I HAVE A EXT.TUBE FOR THIS CAMERA.
Read the review and see if it mentions attachment thread size. If it is threaded you can take it to a camera store and try different filters to see which size fits. As for infrared, you first need to test the camera for infrared sensitivity. Traditional infrared filters like the 87, 88a or 89b will work if there is sensitivity.
Thank you Larry,that helps.
