My lenses (beside the 45/2.8P and 16/2.8 AI-s) are dated before 1975 or after 2010. 
Funny

. Was this intended, or did it "happen" ?
But it begs the questions what will be your strategy to fill the 35 year "void" from 1975 until 2010 ?

Moving from time series to focal length series: i.e. 4x 300mm lenses
from left to right: f5.6, f4, f2.8, f2
(750gr, 1450gr, 3100gr, 7100gr)
