Not that it's terribly significant but 3.5 is actually 2/3 stop slower 
than 2.8.  1/3 stop is 3.2, 1/2 stop is 3.4.

I'm showing off. :-)  Now that I've got a digital read-out for shutter 
speeds, aperture and ISO all in 1/3 stop increments I'm beginning to 
memorize all the intermediate settings.  But I did have to calculate the 
1/2 stop increment.  Actually, the precise value is 3.43.
