It’s the world’s first snorkel lens system that allows live panning of the objective lens while maintaining a level horizon.
The built in image orientation optics allow the image to be rotated to any position within a 360 degree circle.
Spinning images can also be accomplished by continuously rotating the image rotation ring.
The lenses for the Revolution are:
9.8mm, 12mm, 16mm, 20mm, 24mm, 32mm, 40mm and 60mm
