MATE 是 M 系統中最具獨創性的鏡頭設計之一——三個定焦質量的焦距集於一身，是終極極簡旅行鏡頭。

徠卡 Tri-Elmar-M ASPH（1998 年）以機械卡位方式在 28mm、35mm 和 50mm 三個焦距間切換，每個位置都有清晰的卡頓感。f/4 光圈不算大，但體積極其緊湊。鏡頭透過卡口上的凸輪自動切換 M 觀景器中的對應框線。「MATE」這一暱稱（Multi-Focal Aspherical Tri-Elmar）廣為流傳。對新手而言：這不是變焦鏡頭，而是三支定焦鏡頭共用一個鏡筒——每個焦距都有獨立的光學公式，銳度媲美專用定焦。

版本與塗裝

Type 1 (E55 filter thread)118901998

First version of the Tri-Elmar-M 28-35-50mm — a three-focal-length manual-select lens using a 55mm filter thread. Unique concept: three discrete click-stop focal lengths in one compact barrel; no zoom, just three primes sharing a mount.
