Condensation in Summicron 50/2 Rigid?

I'm wondering if haze is endemic to the rigid? I bought one a couple of years ago and had it CLA'd by DAG including haze removal, but I couldn't stand the tab/infinity lock thingy. Bought a late DR and sold the rigid a couple months ago. Then I heard back from the buyer about a month after it was sold, he thought there was a hint of haze in the lens. He was actually very good about it and the last I heard he was sending it to DAG as he had an electronic copy of my repair paperwork. Have yet to hear from him as DAG will probably have the lens for ages. But it does make me wonder if once you get haze in the lens it's never totally eradicated... 😕

I didn’t have mine cleaned because of haze, it was little bits of black flakes inside the lens one of which was bang in the middle of the rear element … and I get a bit obsessive about stuff like that.

I was just pointing up the need to use a competent technician. Sorry I didn’t make that clear
 
No expert here; I wish I knew. There is probably a good reason why new equipment is shipped with Silica Packs to absorb moisture.
 
Yes -- many people use a ziploc bag, few bother to put in a silica gel sachet. I always have a few scattered in my camera bag and equipment drawers. I'll start putting them into the packaging when I ship a lens.

Roland, Brian: Why do you think that might happen? Pressure, temperature, moisture are all that come to mind. Vibration seems an unlikely villain, being present in cars, trains and so on.

If the lens is shipped from somewhere that has high humidity or has been in a damp environment then the drop in pressure on an aeroplane, approx cabin pressure equivalent to being at 8000ft would cause the moisture to condense and form misting.
The other reason could be that some aircraft holds are lower in temperature than the cabin and since cold air holds less water vapour than warm air the moisture vapour condenses.😀
