50 summicron easily dissemble, normal?

[j._b.]

Hi, I have recently bought a 50/2 rigid summicron(s# 146...). I just found that the lens can be disassembled easily from the middle between aperture ring and foucus ring. Is it normal? Anybody has similar experience? Will it results in inaccurate element-to-element distnace and bad sealed protection? I am new to Leica and would liek to hear your opnion.

That's the way it's supposed to be. They even made an adapter so you

could hang the glass onto the front of the bellows.

The early 50/2 lenses were made so the lens head was removable from

the mount for attachment of several different close-focus or copying

devices. 90 and 135mm lens heads were also removable for use with

either bellows or short helicoid mounts on the Visoflex reflex

housings.

I have had a similar experience with my rigid 50mm Summicron but since

I got it back from Leica for a cleaning, etc., I have not attepted to

take it apart. I originally did disassemble the lense partially out of

curiosity. Now that satisfied, I will just use the lens to take

pictures.

I'm new to Leica too and my used but not so old 50mm Summicron,serial

no.3540610 also comes apart as described.Is this normal for a later

model or does it need repair?
