Hi,

Do you guys happen to know how to open a leica lens? need to clean the haze. I have a 50mm summicron, made in canada with tab. Thanks.

The only way I open a Leica lens is by sending it to a trained technician.

I agree, that is really the best option.

My late friend Sheldon Brown designed
a precision instrument for just this purpose:

Get a good grip, and just reef on it
Should do the trick

I successfully opened a Mamiya lens years ago. Ended up sending all the pieces in a box to Paul Ebel so he could put it back together.

This guy and some high explosives should do the trick, along with a pipe wrench, of course..

Generally, you must remove the face ring. But it depends on the lens. If it has slots, you can use a spanner wrench. Otherwise, you can use a rubber plug.

However, some lenses aren't easily disassembled and require special tools.

Upon reassembly, you should recollimate the lens.

Sheldon's Tork-Grip also functions as an inertial impact alignment tool.

As for cleaning the lens cells, the diaphragm, and collimation, it is next to useless.

I'm pretty sure DAG is much less expensive than a genuine Tork-Grip.

hey guys... you guys are sooooo cool.... I was with a guy who fixes cameras but didn't know how to open this type of lens.... I've decided to send it to DAG....
thanks a lot for all the inputs.

Steve Grimes always said it was never a good sign
when you gave your Leica to a repairman who said,
"Oooh ! I've always wanted to work on one of THESE !"

good luck dx !

I've disassembled a Type I Rigid Summicron, several collapsible Summicrons, Summitars, a Summar, and 9cm Elmars. I would vote to send a more modern lens to DAG, Essex, or Youxin Ye or other experienced person for cleaning.

I would not take apart the newer Leica lenses.
