It requires desharpening every step of the way when resizing for the web...

Sorry, but I have to wave the bullshit flag on that comment. There's no way a normal image requires "desharpening" when downsizing with a normal bicubic resampling algorithm, no matter what the lens was. Quite the contrary, actually. Downsampling causes some loss of edge definition, which is why most people slightly re-sharpen images for web publication. Things may be different if you use a resampling alrgorithm that applies sharpening to the output (but that's independent of the lens, too).
