Gecko-Cam Genesis Opia 18mm T2.0
(INSERT SINGLE HERO IMAGE HERE - other images below in media section)
Summary
The Genesis Opia Lenses stand out with their stringent optical design, which only uses spherical lenses and creates a highly admirable look.
Housed in a high end mechanical system using latest materials and manufacturing methods. Driven by a focus cam, machined within tight tolerances on the most modern CNC-Machines and new developments in bearing design and material choice, these lenses contain the best from both worlds. Optically and mechanically.
While the longer focal lengths, above 35mm, are based on what is called a split triplet the shorter ones are a retrofocal design. All lenses are coming with a consistent T-Stop of T2 throughout the series.
The special way this lens design was optimized makes it possible to maintain the character of the lens by controlling background sharpness and decoupling it from Iris adjustements. When shot fully open it shows brilliant textures and even sharpness transition.
All focal lengths perform with high contrast at the image center while the image corners tend to show a lower but harmonic resolution.
