I have 2 Multicoated lenses and 2 single coates lenses. I notice a real difference in B&W between them. My Symmar is pre-multicoating (by 6 months) and in the folliage, I can see a reduction in sharpness caused by lens flare like halation under a lot of magnification. It is something that only I notice but it does keep my using the MC lenses more often if I can get away with it. My 300mm single coated Schneider is OK but nowhere near as sharp as my 210 Sironar or Caltar(Grandagon). Maybe in 8x10 it is less pronounced as it is yet another order of magnitude in the negative to print ration. -Frank
