So I take only hot showers.

I must admit that I never changed a sreen of the SL 35 E myself. But what
is said is that the  foundation plane for the screen is not  precisely
enough defined. That was the reason to introduce the supporting frame for
the SL 2000. This maybe wrong, but that is what Rollei repairman say.
However, if you change the screen and test it with a properly adjusted lens
(those are hard to get because the tolerances have been quite high) at
infinity, and you have no problems, everything is fine.
