Well, the SMCP 85/1.8 and the SMCP 105/2.8 are ~very~ different in their bokeh characteristics. They also have a very different optical design. The 85/1.8 employs 6 elements in 6 groups, while the 105/2.8 uses a somewhat simpler 5 in 4 configuration. > a finding that one was substantially sharper than the other would > lead me to carry that one and not the other under most conditions. My experience is that the 85/1.8 and the 105/2.8 are both quite sharp lenses. Fred
