So we all know and revere the L glass. I do. But a recent test with one of these lenses here at work has shown me something I don't understand.
I was just goofing off trying to find out just how much this 70-200 2.8 L lens would kick that cheap Pentax 55-300. (At a $1800 higher cost, it had BETTER!) I photographed a camcorder which was sitting about 1m from me. Here's what I saw:

Yes, the Pentax has some real noise issues which I've never liked, but look at the clarity of the image. With the L lens, there's chromatic aberration and general softness while the Pentax has none. Yes, I retook this shot again and again with both cameras to confirm. Yes, I shot different things. Here it is again:

What's going on?
By the way, I chose 100-120mm and f5.6-f6.7 for each lens because that's where they're sharpest.
