"I believe both 35mm and 50mm summilux have the clearance issue. I never tried the 50mm, but it was discussed to death on fred miranda forum..."
Interesting information. Although I have never had a problem, it is very possible that I was lucky, and that I have never used this lens at infinity.
Today I got the 50 mm Summilux out, and noticed that indeed, the rear element comes right out!
Thanks for making another reader aware! ....
