Which Photo Was Shot With a Canon L Lens?

I’ve been very impressed with both lenses during this test period. I often have a hard time finding any difference between them when it comes to IQ and I was wondering if it’s just me or are they really that close in performance? So, I’ve decided to pull a page out of Mr. Gampat’s book and do a little test with our readers. Can you match the photograph to the lens?

Equipment

The Test

Note: I tried to strip all of the EXIF data from these images but I’m sure there are people out there that can pull exposure/lens info from there images. Please don’t cheat. And if you do decide to cheat, keep it to yourself.

Both images where shot with a Canon 5D (mounted on a tripod) using the same settings (ISO 500, F/2.8, 1/6 sec, -1/3 EV). A wireless trigger and mirror lockup was used to minimize/eliminate any camera shake.

So, which one is the L and which one is the F/2.8 USM? Leave a comment and tell us what you think. Also, please tell us how you came to your conclusion.
