Leica's R-mount 90mm f/2.8 — Elmarit with ROM electronic contacts for late R bodies.
The Leica Elmarit-R 90mm f/2.8 ROM is a portrait telephoto for the Leica R SLR at Elmarit (f/2.8) aperture class. ROM = electronic coding for R8/R9 bodies. A more compact and affordable alternative to the APO-Summicron-R 90mm. Leica R mount.
f/2.8 maximum aperture. 90mm focal length (full-frame). ROM electronic coupling (R8/R9 compatible). Manual focus. At approximately 540g. 55mm filter thread. Leica R mount.
The Elmarit-R 90mm f/2.8 is compact and capable at a substantially lower price than the APO-Summicron-R 90mm ASPH. The 55mm filter thread vs 67mm of the APO makes this more portable. For adapted mirrorless use, ROM vs non-ROM is irrelevant.
On the used market the Leica Elmarit-R 90mm f/2.8 ROM is a capable portrait prime. Condition checks: 55mm front element, ROM contacts, aperture blade operation, focus ring smoothness. Leica R mount — requires adapter for current cameras.
