值得关注别名 "MATE", "Tri-Elmar MATE"

MATE 是 M 系统中最具独创性的镜头设计之一——三个定焦质量的焦距集于一身,是终极极简旅行镜头。
徕卡 Tri-Elmar-M ASPH(1998 年)以机械卡位方式在 28mm、35mm 和 50mm 三个焦距间切换,每个位置都有清晰的卡顿感。f/4 光圈不算大,但体积极其紧凑。镜头通过卡口上的凸轮自动切换 M 取景器中的对应框线。"MATE"这一昵称(Multi-Focal Aspherical Tri-Elmar)广为流传。对新手而言:这不是变焦镜头,而是三支定焦镜头共用一个镜筒——每个焦距都有独立的光学公式,锐度媲美专用定焦。

版本与涂装
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.
Type 2 (E49 filter thread)11625
Revised Tri-Elmar with a smaller 49mm filter thread — lighter and more compact than the original. Same three click-stop focal lengths (28/35/50mm); the version most often seen on the used market.
