How many of the 50L's beloved image qualities transfer to crop format? I assume that DOF is less razor-thin (by a hair?) on a crop, but is the difference enough to cause disappointment? Same question for bokeh, which is often referred to as "dreamy." I've looked at the images in the lens archive but they usually don't show the camera used. Exif would help, but I do 99% of my browsing on an iPad and I'm not sure how to view exif on that platform. Mostly though, I want to hear from actual users since, probably more than any other lens, it's so hard to judge from specs alone.
I'm thinking of buying a 50L this year because I love the look of the images I've seen with it, and I used to own a 55mm FD lens back in the film days, but I'm concerned that my expectations may be too high for crop use. FWIW, I also plan to buy a 5DIII next year.
On a related note, someone posted a thread a while back in which he accused Canon of bumping the ISO in-camera when shooting at f/1.2 to make it appear that more light was reaching the sensor than actually was. Is that true, or was that theory debunked? Seems like a pretty scathing accusation if true.
