Product Details

The AquaTech BT-145 Lens Tube designed for the 24-70mm f/2.8 II from Canon. This Tube features a sliding tube design to accommodate with the lens extension when zooming and eliminating the problem of vignetting.

 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.

FEATURES

• 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.
