APO-Summicron-M 1:2/75 ASPH lens hood came off

I screwed a heliopan ES 49 lens hood onto the 75 Summicron. When I unscrewed the heliopan, I accidentally also unscrewed the ring that holds the 75 Summicron integrated lens hood in place and that hood fell off.

 

Although the integrated lens hood doesn't seem to work very well, I put the pieces easily back in place, as without them the 75 Summicron looked a little bit funny.

 

So, now I know what to pay attention too to make sure I don't accidentally lose parts of the lens when I am out shooting.

K-H. I had the same thing happen with my brand new 75mm Summicron several years ago as I took it out the box. The retaining ring was loose and it came off in my hand along with the lens hood. It looked like a bit of a flimsy arrangement with this ring which holds the hood in place.

 

If I recall I pushed it back into place and turned it as well, I was very tempted to use Locktite (sound familiar?), but thought better of it.

 

Since then I've always been extra careful whenever extending the lens hood. Always twist and lock the hood into place when it's extended.
