■UWL-100 28AD Wide Conversion Lens
●Dual use (land / underwater) wide conversion lens specially designed for 28mm wide camera (35mm film equivalent). The maximum view angle is 100°underwater for wide imaging and179°on land for fish-eye imaging.
●Compact size for easy handling underwater; outer diameter: 87.4mm, height: 43.2mm, weight: 370g (*excluding optional lens hood)
●In addition to ultra wide angle of view, optical design of the UWL-100 28AD allows closer focusing distance which benefits you when shooting wide macro image.
●Optional "Dome Lens Unit II for UWL-100" further widen maximum angle of view to150.8°underwater for semi-fisheye imaging.
●Optical construction consists of 4 elements in 4 groups with coated optical glasses which effectively suppress optical aberrations and elicits master lens performance.
●Bayonet "28AD Mount" compatible to support instant installation and speedy lens exchange underwater.
●The UWL-100 28AD is attached on compatible camera / housing via "28AD Mount Base" or "28AD Port" which is exclusively designed for each housing (*1).
(*1)The UWL-100 28AD is designed for 28mm (35mm film equivalent) digital camera so not usable for "AD Mount Base" which is compatible with 35mm standard digital camera though the lens is physically attached on it.
The first step in shooting impressive underwater images is to get close to a subject. If you shoot distant subject, you may get bluish or whity blurred image because of the amount of water between the lens and subject. It is essential to use a wide conversion lens to shoot wider at close distance.
A wider lens enables you to shoot • • • • •
• wider underwater landscape
• group photo with more divers in clear image
• bigger subject like manta in single image
• bigger subject clearly for closer shooting distance
[When using a wide conversion lens]
*When shooting without an external strobe, it is recommended to use ambient light only instead firing the built-in flash since the built-in flash light may be blocked depending on a housing design, shooting distance or angle of view etc.
*Set the camera to wide end. If you observe vignetting at wide end, zoom to telephoto side minimum necessary or crop the image after taking image. The lens is designed to get optimum performance at above setting.
