How does the angle of view change when a wide conversion lens (hereafter referred to as "WC") is attached compared to without the WC? All cameras share the same DX-2G camera housing set. 24mm (35mm film equivalent) is the wide side of the 2G camera. When the WC is attached, it expands to 16mm (35mm film equivalent). We compared the results of "without WC" and "with WC" in a variety of situations. *All photos were taken without the zoom function. 2G camera mode is SEA&SEA mode.

For a subject like the Napoleonfish, which is large in size and can be approached, a standard lens will not be able to fit it in the picture. With a WC lens, the subject will fit in the picture and give it a sense of depth.

Comparison shot of a school of snappers, with the WC attached, the water layer is removed and the image is clearer as you get closer to the subject.

Comparison shot of the blue hole from the same position. A WC is essential to capture the light coming through the hole in such a small space.

Comparison shots of manta rays. The reason why the size of the manta ray is not much different between these two pictures is that the manta ray is closer when using the WC.

Comparison shots of a school of red clownfish. In the left photo, I tried to include the whole school without WC. The strobe light did not reach the whole group. In the photo on the right, I took a close-up shot with the WC attached. The strobe light is reaching the subject well.
