Schneider/Rodenstock lens care

[gazwas]

I'm sure I've seen this mentioned on a hear and I hope it doesn't sound like a petty question but is there a best practice procedure for using and storing LF digital lenses?

Basically I'm asking should you cock the shutter after setting the shutter speed or before?
Also should the lens be stored shutter open or closed with the shutter cocked or not?

This is from Alpa, they have answers to most questions 

"Tips: Copal 0 and 1 shutters - Correct handling

Back in analog times everything was a little bit easier. Photographers were photographers and the number of actuations of the shutters low. Now in the digital times the number of actuations has increased dramatically. This might be the reason why some restrictions become more obvious. Copal avoided to mention that it is a bad idea to change the time ring after cocking the shutter! To be clear: If a photographer constantly changes the times after cocking the shutter (especially times around 1/30 sec) he or she will destroy the shutter sooner or later. One can observe a golden shiny covering of the aperture blades from the abrasion of copper.

In order to avoid expensive repairs, please check for proper handling!"

Thanks Adam. I should have checked the Alpa website (even though I'm an Arca user) as it offers a welth of info but didn't think.

Now you've said that, I remember with the LF films lenses I used to use, if you changed the shutter speed after cocking the shutter it sometimes sounded like you were trying to force a timer to finish quicker. Obviously not good for the shutter.

How about storage in the camera bag. Shutter cocked and tight or fired and loose?

Shutter uncocked and set to T

Cambo also has a statement on the same issue:

Thanks Steve and everyone else. This was just what I was looking for.

How about the Compur and Prontor shutters in MF lenses? Would similar constraints apply to them?

I'm obviously no expert but I would imagine the same applies as they too are mechanical shutters and can't differ that much from Copals.
