I have had the 24-70/2.8 II for a couple of months and I realise now that I have not used the 35/1.4 since. Obviously an f1.4 can do things a f2.8 can't but is DOF really an issue for a wide lens? And I have the 5D MKIII so light/ISO is not that much of a problem either. I was just about to put the 35/1.4 up for sale but I simply can not make up my mind.... Opinions are more than welcome.
