With the Hoya S-HMC we get 46,44,39. Now we see a more measurable difference between no filter and the multi-coated, perhaps because the lens has more contrast to start with at this focal length. Probably not a very noticable difference in all but the strongest contra-light situations (like this contrived one), but nonetheless there is a difference.
