Review: Light & Motion's Fathom 90-Degree Lens

September, 2008



Light & Motion's Fathom 90-Degree Lens $900.00


Review by Steve Douglas

Any videographer worth his or her salt knows that without a good port on their housing, their images will be reduced in color saturation, resolution and, often size. While a bit more expensive than standard plastic ports, for those wanting to film up to their camcorders very highest standard, the Fathom glass lens, by Light & Motion, is the only way to go.

Once I had my hands on this beauty I knew in my heart that my film work would only go up from there offering exceptional depth of field, saturation and ease of filming. The quality of the Fathom lens is evident and intrinsic to every Fathom lens I have ever used. The Fathoms 90 degree wide-angle lens increases your field of view by 25 degrees from the original standard 65 degree port to a full 90 degrees.

I have frequently encountered videographers who were concerned that they would be using the right lens for a particular dive. Should they switch to their macro or flat port with diopters, use the standard wide angle or super wide angle? With the new Fathom 90 degree lens, the question becomes moot as this lens really can do it all, macro or wide angle with ease.

Vignetting can be a frequent problem with underwater video systems and it is now a relief not to have to worry about it. During use, no matter where or when I used my zoom control, there was absolutely no sign of a vignetting problem. While I do not use my zoom controls very often, chosing instead to get closer to my subjects, the Fathom 90 degree lens offers full zoom through ability allowing the videographer to get near 1:1 magnification at full telephoto. While testing the lens in Costa Rica, I discovered that the only limitations which existed were those presented to me by my camcorder. The Fathom Lens did all that Light & Motion, a continual leader in underwater photo and video systems, said it would. Soon to be released will be a Fathom 110 degree lens which I hope to test for you as well, especially as it has been touted as having the ability for 1:1 macro reproduction in full zoom.

The bottom line on the Light & Motion Fathom 90 lens is that it is a shame that it wasn't available sooner. Now that it is, for the underwater videographer it automatically makes itself as essential as the housing itself.
