Community Role

Ian Marsh was an active Wetpixel community member from 2012 through 2023, contributing 261 posts with a particular focus on advanced wide-angle optics and high-end housing systems. He was notably engaged in discussions around Nauticam’s Wide Angle Corrector Port (WACP) technology and was also a collector and user of legacy Nikonos equipment, bridging the gap between classic film-era underwater photography and modern digital systems.

His equipment interests spanned Seacam and Nauticam housings, and he was an active participant in the classifieds, buying and selling high-end gear including Seacam components and Nauticam port adapters. His willingness to invest in cross-system compatibility solutions (such as Nauticam port adapters for Seacam housings) demonstrated his commitment to assembling optimal underwater photography systems.

Notable Contributions

• Nauticam WACP discussion (71 replies): Participated prominently in the major community thread discussing the introduction of the Nauticam WACP (Wide Angle Corrector Port). This thread, with 71 replies, was one of the most significant gear discussions on Wetpixel, as the WACP represented a paradigm shift in underwater wide-angle photography by providing optically corrected wide-angle coverage through a flat port system rather than traditional dome ports.

• “Nikonos Nikon R-UW 13mm Lens Repair” (9 replies): Started a thread in July 2016 seeking repair facilities for the legendary Nikon R-UW 13mm underwater lens, one of the most sought-after Nikonos lenses ever made. His lens had coating damage on the rear element but was otherwise in excellent condition. He noted that Nikon considered it too old to service, highlighting the challenge of maintaining classic underwater photography equipment (^[1]).

• “WTB: Nauticam Port Adapter for Seacam ports” (11 replies): Sought a Nauticam-to-Seacam port adapter, demonstrating cross-system integration interests and contributing to discussions about port compatibility between housing manufacturers (^[2]).

• Seacam equipment sales: Listed Seacam equipment “a la carte” in the classifieds, reflecting transitions between housing systems (^[3]).
