Canon 50mm comparion

I have all three Canon 50's in my possession for just a few hours, so riddle me this - which image came from which lens? All were shot at f/1.8. (I forgot to remove exif data - no cheating!)

I had it backwards looking at the bokeh. Then I looked at the detail on the lens and reversed my choice. Upon looking at the exif, I was right to change my mind.

2, 4, 8.

8, 4, 2

4 2 8

2, 4, 8

Well I was wrong, I thought I could tell by the amount of aperture blades in the bokeh but apparently not!

Well, the last one seems nifty because of the bokeh. But I'm looking with my iPhone.

i think this goes to show that how great quality all these canon 50s are

Assumimng in focus I would go 1.2, 1.4, 1.8

1) 1.2 - More contrast than the others (much more than the last), smooth bokeh, and you can see slight evidence of the aperture blades in the cut bokeh ball toward the upper left.
2) 1.4 - Could see the evidence of aperture blades in the bokeh balls, otherwise I would have trouble telling the difference between this and the 1.2 with such a small image.
3) 1.8 - Bokeh is a little busier, not as much contrast.

With such small images, trying to differentiate between lenses is almost pointless, since you'll get awesome results out of any of them. Post some full resolution samples and this wouldn't be a challenge at all.

Try to read the is and usm notes and tell me you can't tell them apart.

Aperture blades don't show up on the f/1.8 when it's wide open.
