Made from aerospace-grade aluminium to resist warping, impact and environmental wear — ready for demanding conditions.
Machined to exacting tolerances, the adapter ensures a perfect fit — preserving performance and alignment across your gear.
A Certified B Corp, Urth meets high standards of social and environmental responsibility, ensuring a 10x net-positive impact.
Although Pentax K and SIGMA SA are slightly different, this fits extremely snugly into my SIGMA sd Quattro. Exactly what I was looking for to expand the amount of options I have access to beyond just SIGMA SA.
Sturdy, well machined and solid. Allows my manual Nikon lenses to be mounted on the Sigma SD Quattro (Pentax K mount) with no problem, and they do focus to infinity. Although this usage is highly specific I do recommend for Sigma users.

Urth Art pieces are custom printed and framed so you can experience their full impact in person.
Partnering with a local Australian archival framer, Urth Art prints are framed with sustainably sourced timber to display the artwork, without damaging the environment. And to bring the gallery experience home, Urth Art prints are protected by art-grade acrylic glazing that prevents fading and discolouration.
