I don't see why the 35mm L gets so much praise on sharpness. I received a CPS evaluation loan and it was never sharp wide open and I was completely underwhelmed by it considering the applause it receives. Heck the cheapo 50mm 1.4 was twice as sharp wide open and half as much.
Now the 24mm 1.4L II really impressed me! Great color and very sharp wide open! I prefer it much over the soft 35mm I received to evaluate and is great on crop cameras & full frame.
That lens was disappointing and hope canon revamps it soon. I might reconsider it then but not likely.
Maybe it was dropped on its head one time too many?
