Konica IIIa is what I will choose for the rest of my life, and Rollei 35 S (although not a rangefinder)

Yes, the Rollei is a legend. I haven't tried the Konica, but it looks beautiful indeed
I like the rangefinder patch in Canon P although it pales before Leica M

Indeed it does, but I agree, it is nice anyway.
I want a kiev 4 for the fine focusing, but i love my FED 2 for every day.

Yes, the FED-2 is nicer in hand, and is not bad for focusing either, even though the Kiev is hard to beat in that department
The canon 4sb2 has the effective base lenght of 25 with the shortest magnification, right? So if we set it to 1.35 we will have ~50mm, is that correct?

Well you have the magnificationsettings of 0.67x, 1x and 1.5x, and then you have a base length of about 25mm, 37mm and 55.5mm
