Testing my new Quantaray 500mm F8 Super Telephoto Lens With Preset Aperture. Three of the shots were handheld and one with a my new Dynatran AT-828 tripod. The one taken with the tripod was with my 2x teleconvertor attached making it a 1000mm lens shot. Add the 1.6 multiplier and it's equivilent to 1600mm! Most shots had a focal length of about 50 yards. It appears that the 1000mm setup will require lots of sun light and/or a tripod.
