10.5mm Lens Advice

As others have said you need to get in real close with this lens. Couple of shots to give you an idea of distance from subjects

Turtle shot was taken from no more than 14" away.

School from about 2' range

Shark from no more than 4' away, shark was a good 5' long

(none have been corrected)

Like the others said keep your strobes behind the plane of the dome, and next time I will put them higher up, 11 & 1 positions, pointing out and down a

little.

Looks like someone's been to Hawaii...:-)

Here are two shots with the 16mm fisheye (full frame, film, you can expect identical results on the digital 10.5).
