Flaring Summicron- shade or exchange?

[Jim Jones]

A rectangular vented Canon hood works well on my old 50mm Summicron. I have no experience with modern 50mm f/2.8 Elmars, but the early one I tested was even sharper than the Summicrons. The test didn't include flare, though.

Thanks for everyone's contributions here. I seem to have solved the problem in the main by acquiring a (non-Leica!) screw-on lens hood for a few pounds on ebay- I hardly get the problem now. It does seem to do a better job than than the retractable hood in the lens.

Thanks for all your comments.
