Well I have two big points.
I hope they dont stick out too much.

One: the lens shade on the current 50 is dog-doo as i'm sure you know.
When it is out it sticks out a quarter of an inch, big deal.
But most the time it is in because it gets knocked in.
So a lot of people with the current I think also get the lens shade
which came with the one before.
The one I have as that's the lens i have.
A very involved design which obviously took quite a lot of thought and
trial and error.
Mines plastic but I've seen them in metal. Fifty Bucks.

A lens shade on a 50 can stick out quite far and do a whole lot.
On a wide angle it cant stick out very far; what's it going to do? Stop
you from chipping the side of your glass?

With the Leica we need cutouts and other indentations to make the 50 and
other shades work right but the lens shade made for the 50, the one
which comes on and off is a very efficient thing which I'd not leave
home without.

If my lens flared without it I'd never know and wont know.

I have to say if your talking about a flare problem but no lens shade
then I'm not convinced you've got a flare problem.
That's like saying you have a dampness problem and you're in a filled
bathtub in your pajamas.
Dry bathtub. Dry pajamas. Then lie there silent listening for a leak.

Some big lens tester person has declared the Leica 50/2 to be "known for
flare". I'd like to hear that from a second "expert."
But again i agree that paint problem you mentioned could be the culprit.

Are you going to have your lens CLA'd and while their at it put that
paint in there?

I'd say it would be worth it. The 50 Summicron is a center of Leica.

Let's nip this "known for flare" internet rumor at the bud! I think
that's what it is.
