뭐.. 여러가지 렌즈들 이름이 모두 다릅니다.
그런데 아래와 같이 이름들이 생겨졌다고 하네요~

ELMAR lenses (f/2.8-f/4) took their name from old Elmax lenses. Elmax was an acronym of (E)rnst (L)eica and (Max) Berek.

ELMARIT (f/2.8) was derived from its sibling, the ELMAR.

SUMMICRON (f/2) had the first part of its name (Summi) taken from the Summar lenses of old. The latter part, cron, refers to the fact that the lenses originally used Crown glass (which was produced by a company Leitz acquired).

SUMMILUX (f/1.4) has the same prefix as its slower sibling, the Summicron, but has “lux” attached to the end to indicate its additional light-gathering powers. “Lux” is latin for “light.”

NOCTILUX (f/1) is the mother of all fast Leica lenses. It has both parts of its name dedicated to the fact that it’s a beast in low-light situations. “Nocti” is from the word “nocturnal”.

낚시 릴 감듯이~ 부푼 기대에~ ^^*
