Shooting with the Nauticam WACP, Porthkerris - June 2018

Article text

In June I was lucky enough to spend a weekend using Nauticam's new Wide Angle Corrector Port, on loan from Alex Tattersall at Underwater Visions. Ltd.

Pictured here is an edible crab and diver shot from the Helford estuary in Cornwall.

This lens is a different approach to optics and is designed exclusively for full frame digital SLR cameras. This is an optically corrected water contact lens that does away with the need for the customary wide angle lens and dome port combination. It promises better picture quality, especially towards the edges of the frame.

I used the WACP with the Nikkor 28-70 f3.5-4.5 D lens, giving me a zoom range and with an impressive 130 degrees of coverage at the wide end, through to 57 degrees at the long end. This lens is a lot of fun and the ability to focus with subjects right on its glass front element makes it very useful indeed.

My initial impression is that this is a highly versatile lens that will replace any current rectilinear wide angle lens behind any dome port. In use, it feels like the ultimate mid range zoom that has the widest angle of coverage currently available. However, It does not replace a fisheye lens and dome port combination for when 180 degrees coverage is still needed. The images achievable from lens are nothing that couldn't already be taken but from my limited testing the promise of higher image quality seems justified. For me, the final verdict on whether the 3 kg weight and cost of this lens suit my photography, needs further deliberation.
