Summicron-C 40/1.4 Lens Cap

Yep, bought a Heavystar metal hood, and fit a generic lens cap over it. Works wonderfully.

The official Leica lens cap for the 40/2 is a flexible rubber thing that fits on the thread for the Series 5.5 filter. And as others have said, it isn't a standard E39 thread. And the official lens cap is a snap-fit hard plastic cap.

I think that was the biggest complaint of the otherwise superb lens - the quirky hood and cap.
 
HeavyStar makes a cap for their hood as well as the adapter from Series 5.5 to 39mm

I have this adapter for my Summicron 40/2 and the generic 39mm vented hood with cap, and it worked pretty well until it got stuck on there one day...Really, really stuck. I ended up loosening the lens in its mount in the process of trying to remove the adapter, and had to get out the lens spanner to tighten it back down again.

Maybe it was a change in temperature or something, because just the other day I tried to simply twist the adapter off again and it screwed off the front without any hesitation. Now the adapter seems to be stuck to the vented lens hood though. :/

I bought both items through Heavystar, and can't say that I have any complaints about the build or quality of them, but I'm not putting it back on the front of my lens. I would recommend that if you find it stuck to the front of your lens because you put it on there in summer, and it's now winter... wait for a warm day to come around, it might twist off with no problem.

I've since moved back to using the inconvenient and quirky series 5.5 rubber hood and push on cap.
 
Interesting that Leica still has inventory. It was passed around years ago they were no longer available from Leica. Guess I'll have to investigate as I have neither and relied on the Mickey Mouse route.
