BT-100 Lens Tube
The AquaTech BT-100 Lens Tube designed for Canon 85mm f/1.2L .
Each Lens Tube has been specifically designed to work with our new AquaTech Shadow & Scout Sound Blimps and the associated lenses you can find on our BT-Series Lens Tube Cross Reference Chart. A Lens Tube Reference Chart can be found in the product images, this will help you identify the correct Lens Tube for your lens. If you cannot match your lens with a Lens Tube on the Chart, please contact AquaTech. To function properly, your Sound Blimp requires the use of a Lens Tube that threads to the front of the main body.
• Interior Acoustic Foam – Minimizes sound emission while engaging zoom control (where applicable).
• Capture Ring – Screws on and off to hold our Schneider Optical Glass Elements in place.
• Element – Replaceable Optical Glass element.
• Piston O-ring – Positioned near the port threads creating a seal between the Sound Blimp Body and the Lens Tube.
