About
Everything has a history. Lenses more than most!
MOHR Lens Service is a one-person workshop in Solna, just outside Stockholm.
I’m Martin Rodensjö — lens technician, fine mechanic, and CNC operator. I service, modify and rebuild cinematographic lenses for rental houses, owner-operators and cinematographers across Europe and beyond.
Background
I grew up in a family where precision mechanics and optics run deep. My father was both a watchmaker and a licensed optician — two disciplines that, between them, contain most of what cine lens work actually is. He was also the family’s photographer and filmmaker; weekends and holidays were documented with a director’s seriousness that we children sometimes resented.
The photography came from my mother’s side too. My grandfather had photographed with his Leica since the 1930s. Her cousin was Peter Sinclair BSC, a British cinematographer who lensed music videos through the MTV era — Material Girl, Karma Chameleon, Love’s Great Adventure — and features such as The Full Monty. Sinclair’s brother, Christopher Angeloglou, joined The Sunday Times Magazine in 1962 as Picture Editor and now edits the journal of The Leica Society. My mother photographed too, mostly clinical work at the pathology department.
Cinema lenses are precision mechanics applied to optics, used in photography and cinematography. Every discipline in that sentence is somewhere in the family.
After a detour through music — recording in the 1990s, then audio software development — I came back to mechanical work, this time on optics. It turned out to be where I always belonged.
What I do
I service primes, zooms and anamorphics — vintage and modern. The shop is factory-certified by Zeiss, Cooke and Sigma. The Cooke certification followed a week of in-person training at the factory in Leicester; the Zeiss program covered the full cine range, from Compact Prime to Master Anamorphics. Work is carried out to manufacturer specification, including procedures, parts and parts ordering.
What sets the workshop apart is that the lens bench shares space with a full CNC machining setup. When a part is worn, missing or no longer available — a focus ring, a gear, a sub-shim, a custom mount — I design it in CAD and machine it from raw aluminium or stainless on-site. Many lenses that would otherwise be written off can be brought back to specification with custom parts.
