Camcorder Lens Adapter Raynox HD-6600PRO55 – 0.66x Magnification, 55 mm Thread, 3 Elements/3 Groups, Black

Raynox HD-6600PRO55 is a compact camcorder lens adapter designed to expand the field of view of compatible Canon and Sony camcorders. With a nominal 0.66x magnification and a 55 mm mounting thread, the adapter changes framing without changing the camera body. The optical construction uses 3 elements in 3 groups and is finished in black. The adapter is lightweight and portable, measuring approximately 40 x 75 mm and weighing 178 g, and it accepts 72 mm front filters for additional control over exposure and effects.

Advantages

The HD-6600PRO55 provides a wider angle of view while maintaining strong center resolution thanks to a distortion-minimizing optical formula that delivers 350-line resolution at the center. Its 3-element/3-group design balances compact size with optical performance, and the 55 mm mounting thread makes it compatible with camcorders that support that thread size. The adapter’s metal finish and modest weight support repeated on-location use without adding significant bulk.

Suitable for

• Widening framing for run-and-gun video shoots and event recording
• On-location documentary and ENG-style shooting where a broader field is needed
• Travel videography when space and weight are limited
• Situations requiring use of front filters (72 mm) for ND, polarizing, or protective filters

How to use

Screw the Raynox HD-6600PRO55 onto the camcorder’s 55 mm front mounting thread until it seats securely, taking care not to cross-thread. After attaching, check framing and focus in the viewfinder or on-screen monitor and make fine focus adjustments as necessary since the adapter changes the optical path. If you plan to use filters, attach a 72 mm filter to the adapter’s front thread. Remove the adapter before storing the camcorder if you will be using a padded case that does not accommodate the added length.

Usage recommendations

For best results, verify that your camcorder supports a 55 mm mounting thread and perform test recordings at different focal lengths to assess any corner behavior. Although the adapter is designed to minimize distortion, slight corner softness or distortion may be visible with extreme wide-angle framing; using higher aperture settings (where available on the camcorder) and keeping key subjects near the frame center can help maintain perceived sharpness.
