MTF Testing the Canon 11-24mm f/4L, the World’s Widest Full Frame Rectilinear Lens

Editor's note: If you're unfamiliar with how to interpret MTF charts, you can find a primer here.

I'll be honest. I'm pretty excited about the Canon 11-24mm f/4 L lens. I love shooting ultra-wide and the chance to shoot this wide with a rectilinear lens on a full-frame camera has me pretty excited. But I'm also very aware of how near-impossibly difficult designing a lens this wide would be, so my expectations were tempered a bit.

There's a reason I'll often stitch together a couple of 24mm shots for a landscape rather than take one 16mm shot. OK, there are several reasons, but image quality is high among them.
