Still trying to See.
I had been using my 35mm Summicron on the RD-1 with the Leica 35mm window cut out lenshood but noticed that I was seeing more flare than using this combination on film. I substituted my 50mm Summicron's hood which has the same size and type of fitting for and the suseptabilty to flare is much reduced. There is no sign of any cutoff in the corners of the image which is what you would expect with a 53mm equivalent lens.
Some other lens & hood combinations may also have interchangeable fittings. It seems it is better to use a hood closer to the focal length times the multiplication factor on the R-D1 than the normal hood for the focal length.
