Canon, Nikon, and Sony 70-200mm f/4 Lenses (and the 70-300 L) Added to MTF Tool

The Canon, Nikon, and Sony 70-200mm f/4 lenses, along with the Canon 70-300 L lens, are now included in the site's Camera Lens MTF Measurements Comparison Tool.
 
When the size and weight (and price) of the f/2.8 models are too much, the f/4 models are the easy alternative.
 
Go make some comparisons, then share them with your friends.
