Originally posted by matroxication Updated to v1.5 and I find the focus in low light is indeed improved. Checked with 77mm limited and it nails the focus considerably faster in low light situation. Yet to test with my 100mm macro which hunts during the low light scenario.
Yes, this is my impression. Also seems a little more focus point specific. I was able to thread through branches to get focus on a bird yesterday.
No better on moving targets, about the same as before. I suspect the additional processing horsepower of the II version helps.
I'm going to recalibrate my 150-450 to see if it changed. Not sure.
