My lens is fogged up… It’s ruined… Failure is not an option! This essential accessory for outdoor photography is designed to defeat condensation — your lens’s worst enemy.
This heater prevents the lens condensation (fogging) that so often occurs during outdoor photography. Now in its fourth generation, the Lens Heater 360 series is renowned for its ease of use and has been redesigned to meet the advanced demands of professional photographers, where failure is not an option.
Outdoor photography offers once-in-a-lifetime opportunities; you’ll never encounter the same breathtaking scene twice. By wrapping the Lens Heater 360 IV around your lens, you can guard against its worst enemy—condensation—and ensure you never miss a priceless shot.
Vixen Telescope Lens Heater 360IV Description
-
Understanding the Principle of Condensation to Prevent It Efficiently
When a lens colder than the surrounding air is exposed to moisture-laden air, the water vapor gets cool and condenses on the lens surface as dew. The Lens Heater 360 IV efficiently prevents this by gently warming the lens to keep its temperature above ambient temperature.
-
Provides Lasting Protection against Condensation
The heater is optimized for power efficiency, maintaining its condensation-prevention effect over extended periods. A long-life design allows it to operate for approximately 14.8 hours when using a 10,000 mAh mobile battery.* This enables you to focus on long exposures without worrying about battery drain, while minimizing any impact on lens performance by the emission of heat.
*Battery life may vary depending on ambient temperature (20°C), usage conditions, and battery characteristics.
-
Easy Attachment! Silent, Stress-Free, Speedy
It features an ultra-thin, flexible heater element made from carbon nanotubes. The soft hook-and-loop fastener—known as the "Mild Fastener"—is praised for its quiet and gentle adhesion. Unlike the ripping noise typically generated by standard hook-and-loop fasteners, it operates quietly, allowing for quick, stress-free attachment and removal without wasting precious shooting time.
-
Easy and Secure Fixation with Finger Hook + Non-Slip Grip
The surface that contacts the lens body has a non-slip finish, and a trapezoidal finger hook is positioned on the side. This provides a convenient grip point, allowing anyone to wrap the heater with light tension for a secure, easy fit and reduces slippage during use. As the "Mild Fastener" is also used for the finger hook, this part can be folded back and secured, staying out of the imaging frame while shooting.
-
Spiral Cord reduces the Influence of Wind
It is equipped with a curly cord that can be wrapped around the camera with light tension, helping to minimize image blur caused by the cord swaying in the wind during shooting.
-
Detachable USB Power Cord
A USB power cord is included, allowing immediate use with a USB mobile battery or other power source. It connects via a USB Type-C connector and is also compatible with other commercially available USB-Cords.
