How does the focus accuracy and speed of the 85 1.8 compare to the 50 1.4? Is the 85 better in low light conditions?



Light projection from a shorter & wider angle lens makes the AF system harder to predict, so i say 85 is better than 50 @ wide open for the same body. Maybe not matter if you have better AF body EX: my 85 works better than 50 on 5d2 but their performance is the same on 1ds2.
