10 out of 10 points and recommendedTHE light. THE color.
bought during a trip in Hongkong, instead of the 28/1.8 (I wanted a 28 because I used a 28 all the time on my film cameras) and the 35/2, after having read the messages on this website. I get used to the 35mm framing. Mostly because this lens brings trully the light I was waiting for. Colors are slightly different when closing the diaf. But I didn't meant it was bad! I prefer this lens at 1.4.reviewed October 1st, 2008 (purchased for $1,150)
This is a typical example of what you get with a 5D:
After having tryed this lens I don't use anymore the 24-105L. In my current trip to Singapore and also in India, I only took this lens + 5D + a pair of leica's M6.
When reading about this lens I was concerned about the vignetting on a full frame. actually there is another example at 1.4 with the 5D: http://www.pbase.com/nicolasdechamps/image/99614485
As you can see you can notice it, but for me it is not at all a problem. Furthermore we usually like to add some vignetting in photoshop, right?
I personnally just find it sad that people stick with zooms as the 24-70L and forget about this prime.
This 1.4 aperture makes the difference, you can really work at night and also make nice portraits.
THis one is a night one, it is not that good but makes my point:
save, buy and enjoy!
