I've been checking on the guys over at http://www.flashflavor.com/
(wedding photographers) and noticed that they are using the Canon 85 and 50 F1.2 lenses on Canon 5D's. Now I'm wondering if we will ever see a lens as fast as the F1.2 on 4/3 ? Is it technically possible ? We have the Leica D 25mm 1.4 but would it be possible to have a f1.2 version of it ? The cost of the two canon lenses is most probably shocking and I thinka Leica D version would be just as costly but if such lenses were to be made and it was within a reasonable price would any one be interested in them ?
