How fast is fast enough for you, more importantly do you wish fast or accurate, sometimes fast doesn't mean accurate, i.e. sharp.To those of you that have compared them, which focuses the fastest?
The 50 1.4G is a slow focuser.Is their a slow focusing 50mm ? I have owned the 1.4 D, the 1.8 D, and I use a 50mm 1.8G at work regularly. They all are fast enough I cant tell a difference in focus speed. On my D3 at work, they all are super fast, but I cant tell a difference from the D3 and my D7000.
I'm very surprised with the focus speed. On a D3, this 1.4 D lens focuses almost like my 80-200 afs. Im picking up a 50 1.8G tomorrow. I'll let you guys know which is faster on a D3.The sigma is easily the fastest focuser but its sloooow in comparison to the 2.8 zooms and long tele's:biggrin:
When I first got the 17-55 2.8, I thought, damn this is fast. Then I tried the 70-200 VRII and that was faster still. Then I tried the 200 f/2 and that is even faster than the 70-200.The sigma is easily the fastest focuser but its sloooow in comparison to the 2.8 zooms and long tele's:biggrin:
