Interesting to note the differences on the two films. First, the grain is
more apparent on the 400f, but I also noticed the tonal range is shortened
as well.

Right; high-speed films tend to be like that. Elite Chrome 200 less than
most... you might try it.

On the 400f's behalf, being able to shoot at 1/500th of a second
makes for consistently sharper pictures - free of most atmospheric
turbulence.

More to the point, it also "stops" the vibration from your camera's shutter.
