fact, it's not even listed on the JVC site. If you can find specs, post either them or the url. The question cannot be answered without specs.

The GR-D396 has a focal range from 2.3mm to 73.6mm. That means that it's '32x', while real, is mainly sales hype. Its lense is not at all powerful, and probably will not be effective in pulling in a distant image.

Long distances are more likely to be acheived with something like a Canon XL2. The XL2, with an adaptor, can use photographic lenses including high power, telephotos. That would not, however, be an inexpensive configuration.
