Thanks guys... in terms of the built quality I know that the 1.4 is better, just like the 1.2 is even better. I was just wondering on the DOF more than anything, i want the blur effect on my portraits and didn't know if it was a significant difference between the 1.4 and 1.8...


I guess if the difference in Speed and DOF is not so big then it comes on to whether I want a better built with faster focusing or not ? because on the IQ side of it they are both good, right ?





BTW, i don't know if this will make a difference, but i have a 1.6 body
