Imagine watching a water tiger capture a tadpole with its piercing jaws.
Many modern camcorders have a 'macro' or 'close focus' setting.
Most of these will focus in the range suitable to the Discovery Scope Camera Adapter. Use the standard-thread mounting screw of the Adapter to attach it to of one of these camcorders and you are ready to apply Discovery Scope's features to the world of video imaging. With one Sony camcorder we use, we find the camera will focus with the subject about 2.5-6 cm. The field of view is about 4 cm. across. This gives us great views of pond samples, spiders, flowers, etc.
