Community Role

Goluchmas is one of the longest-active Wetpixel community members, with an eighteen-year span of participation from February 2008 through at least May 2026. He is a Canon full-frame shooter who has progressed through multiple generations of Canon bodies and underwater housings, primarily from Aquatica, Sea & Sea, and Nauticam.

Goluchmas is based in Colorado, USA, and has been a prolific user of the Wetpixel Classifieds, starting 129 threads — more than any other user in this activity tier. His classified listings and purchases provide a detailed record of Canon underwater photography equipment values and upgrade patterns over nearly two decades. While many of his posts are in the Classifieds section, he also contributed to technical discussions about housing features, vacuum systems, and strobe selection.

His continued activity into 2026 makes him one of the few community members who have been engaged across all three major housing eras: the Aquatica/Sea & Sea DSLR period, the Nauticam ascendancy, and the mirrorless transition.

Notable Contributions

• Canon full-frame gear progression documentation: Goluchmas’s classified listings trace a comprehensive history of Canon full-frame underwater photography systems. His listings included an Aquatica housing for the original Canon EOS 5D with Heinrich E-TTL conversion circuit board (installed by Underwater Photo Tech), a Sea & Sea MDX-PRO for the Canon 5D Mark II, Nauticam housings for the Canon 5D Mark III, Canon 5D Mark IV, Canon 7D Mark II, and most recently a Nauticam NA-R5 for the Canon EOS R5 (^[1], ^[2], ^[3], ^[4], ^[5]).

• Nauticam vacuum system adoption: Goluchmas was an advocate for Nauticam’s vacuum check systems, listing housings with vacuum systems as a selling point and contributing to discussions about vacuum valve operation and maintenance (^[6], ^[7]).

• Canon R5 mirrorless transition: Goluchmas was among the community members who made the transition from Canon DSLR to the Canon EOS R5 mirrorless system, acquiring a Nauticam NA-R5 housing with the Canon RF 100mm f/2.8 macro lens. A 2022 listing noted he was selling due to health problems preventing diving (^[8]).

• Strobe equipment evolution: His listings document progression through multiple strobe systems including Sea & Sea SB-105s, Inon strobes, Sea & Sea YS-D2, and Retra Original strobes, reflecting the broader industry evolution in underwater lighting (^[9], ^[10]).
