Ultra Wide Angle Lens (Micro Series & Reefmaster RM4K)

Description

A fogged dome in cold water cannot be cleared at depth, which is why the inner airspace here is back-filled with nitrogen. That specification is the one that shows on the day, on a cold dive or a hot boat. The lens widens a Micro-series camera by almost 50 percent and focuses three times closer, reaching 196 degrees on a ReefMaster RM-4K, with an effective focal length of 13.3 mm film equivalent on a Micro 3.0. Optics are a 4-element, 4-group array of high grade optical glass, fully multi-coated to stop internal glare and hold light transmission, which is what gives edge-to-edge sharpness. A shade rotates around the front to keep strobe flare and sunlight off the glass, and takes any knocks the dome would otherwise meet. It locks on with a ring and is rated to 60 metres, fitting and removing underwater without ending the dive. The lens sinks, so keep the lanyard on it. It suits a Micro-series owner shooting wide.
