I bought the EF 14mm f/2.8L II. Great seller and great transaction. Paid on Monday, received on Thursday. The lens is absolutely "as new" and performs as expected, like the one that I borrowed from CPS.
I ran out to shoot it, but it was overcast and threatening rain, so my subjects ended up being just test shots. On a 5DsR, 14mm is "ultra-wide", yet, look at the fence piece near the bottom of the image. It's shows almost no barrel distortion. I also tried the excellent 11-24/f4, but it was too bulky for me to carry in my vest all the time. It has similar IQ, which is amazing for a zoom, but it didn't make sense in my application. (Don't let the horizon bother too much. There's a hill going down to the right and a conflicting distant horizon, yet I've probably should have rotated a degree or two clockwise, but I didn't want to crop a test image).
