| p.1 #1 · p.1 #1 · Disassembly - Voigtlander 75mm F1.9 Ultron SC Leica M mount lens | |
@yukosteel has just posted a detailed teardown of the Voigtlander 75mm f/1.9 Ultron lens designed for Leica M mount. (Review here)
One notable excerpt from the article's conclusion is as follows:
"Voigtlander 75mm F1.9 Ultron SC is relatively easy to service by first separating optical core frame from focusing frame. Thick aluminum parts look durable and also very thick brass parts are used for focusing/RF helicoid guiders which explains silky smooth focusing operation even when mounted on M camera. It's great to see that lens has easily tunable precision of RF cylinder and precision of infinity focusing by configuring thickness of shim rings set."
