I've notice the same thing. I go with three lenses:
20-35 50 1.4 100 2.8 or 135 2.5 or Sigma 100-300 DL
I prefer the 100 or 135, but sometimes I need the reach of the zoom. Either way,
I still seem to like the 3 lens approach: wide, normal and fast, long.
I've only got 4 lenses FA 35/2, K 50/1.4, K 55/1.8, and M 100/2.8. The fifth is my M 35/2.8 that I want to sell. I rarely use the M 100/2.8 and almost consider the 55mm a "portrait" lens :-)
My 2 cents.
regards, Łukasz
