I am considering Swapping my 16-35 f2.8 II for a 24 f1.4 II.
When I had my 40D, the 16-35 was on my camera most of the time. The 24-55 effective focal length suited many situations very well. Since getting the 5D3, I have rarely used it and when I have, it has only occasionally been used wider than 24mm.
The lenses I use most with the 5D3 is my 135 f2 and my 50 f1.2; my 300 f4 has been wonderful for the kids lacrosse.
So, as I am looking to add another prime to my kit, i am curious to hear from those who have used both the 16-35 f2.8 and the 24 f1.4 II can comment on their experience.
