56mm F1.2 Focus Speed
1 month ago

I picked up both the 23 1.4 and 56 1.2 this week and have noticed that the 23 locks on focus faster than the 56. The 23 will sort of hunt and lock but the 56 will hunt, hunt and then lock. Just slightly more hunting than the 23 is about the best way I can describe the difference. In low light, the 56 hunts even more.

Has anyone with both these lenses observed similar behavior? I wonder if the extra weight and size of the glass in the 56 is causing this.

I am using them on an XT-1.
