Got one, bought and paid for, now off to try it in the dark on a 1D X.
I would like to hear from anyone with the Schneider 50mm.
Um what can I say, I have learned two things tonight.
1/ What a tremendous camera the 1Dx is in the dark.
2/ Canon can make decent wide angle lenses.
The 24mm tilt shift makes the 24mm f1.4II lens look rather poor.
You can't use f1.4 if you have anything near a corner that will not need to be total mush, in fact you need to stop it down rather a lot. I think the f1.4 is there just for those that think bokeh is where photography arty farty starts and finishes, those people that care more about the bits that are not sharp, it's certainly creamy dreamy in the corners.
The TS on the other hand looks built for those of us (probably only me) that like everything sharp.
I was wavering between switching over to Nikon, this lens from my quick tests makes me very pleased to have stuck with Canon, plus the more I shoot with the X the more I'm thinking it's probably the best camera I've ever used. It is just a one trick pony, but it's one trick is it does everything you throw at it incredibly well and that's an amazing trick.
