In a genuinely unscientific and amateurish experiment, I just put my 35-105 on 
an OM-4 and stepped outside.  With the aperture set to f/11 and the lens 
pointed at a uniformly sunlit wall, zooming from 35mm to 105mm resulted in a 
two segment change in the LED meter reading.  

Looks like it's not a constant aperture lens.  I never really cared.  Even 
though I've got the 35-80/2.8 Zuiko and a 28-105/2.8 Tamron, I often still use 
the 35-105.  It's a really nice lens, whatever the aperture may actually be at 
67mm.
