Behind Ikelite 8 inch domeport (5510.45) on Nauticam NA-EM10 housing. 1 Inon D-2000 strobe +1 TTL on right.

Some editing on the RAW file as I'd also do: Contrast +12, Clarity +15

Smart sharpen 40%, 1,2 pixels.

The 12-50mm is a slow lens, but that's OK for underwater photography, wrecks and (some) underwater photography. When the wreck is going nowhere and there's not much life just use the strobe and slow shutterspeed to capture whatever light is available. Your strobe will 'stop' the scene in it's tracks.

As conditions increase just up your shutter speed and make your aperture larger (F/13 and up for sun)

A shutterspeed of 1/20s with ISO800 is not uncommon for a Dutch deep dark dive…

I'll try some more underwater shots with the 12mm soon. Visibility will be a big factor.

Here's a wreck photo at 24 meters and 14mm width.

Still huge difference with a fisheye!

Rated 200 FT. But not with sand and grime near the sealing O-ring. I have been having freshwater (weird enough never in salt water) trickle leaks in my 8 inch domeport. Should all be history after a service checkout by Ikelite.

The 5510.10 adapter is needed for the Sigma 15mm and Nikon 10.5mm fisheye lenses when used with the 5510.45 8 inch domeport.
