Overview / Product Description
Inon UWL-H100 28LD Underwater Wide Conversion Lens
A dual-use (land/underwater) wide conversion lens specially designed for a 28mm wide camera (35mm film equivalent). The maximum view angle is 100.8° underwater for wide imaging and 179° on land for fish-eye imaging.
Together with newly designed optical construction, using highly refractive optical elements provides larger effective diameter of the rear optical element in compact size to accommodate with latest camera model carrying larger image sensor and brighter master lens.
Unique optical design allows the shortening of the minimum focal distance with an ultra-wide view angle, making it effective for wide macro shots.
Optional Dome Lens Unit II for UWL-H100 further increases the maximum view angle to 144.8 underwater for semi-fisheye imaging.
The optical construction consists of 4 elements in 4 groups with coated optical glasses, which effectively suppress optical aberrations and elicit master lens performance.
Lockable bayonet mounts INON 28LD Mount compatible. Easy, speedy, yet reliable installation on 28LD Mount Base can be obtained.
The UWL-H100 28LD is attached to a compatible camera or housing via the 28LD Mount Base, which is exclusively designed for each housing.
