12585/12571 are they interchangeable?

[photobizzz]

I have a 12585 hood on the way for my 50 Cron, but I will also have a 35/2.8 Summaron and a 50/3.5 Elmar-M soon, and my question is will the 12585 hood work on all 3 lenses? I know the original hood for the Summaron was the 12571/IROOA hood, but I have seen some references that they may be interchangeable?

I dont want to go purchasing another hood unless needed, but would want to go ahead and start looking for one if the 12585 wont fit.

(I do have a 39mm heavystar vented hood that will work on the Elmar)

I use the 12585 hood which came with my DR-Summicron regularly on my 2,8 Summaron. I too used it on my 2,8/90 Elmarit until I bought a screw-in 12575 copy for it. No problem!

Thanks! Saves me $100 or so.
