Originally posted by Prince Harbinger Sounds like you are implying that focus peaking helped you nail focus at F/0.95, and a fast moving subject. As far as something more shallow than F/0.95 try F/0.85 with a speed booster.
Yes, focus peaking worked just like it was designed to, no complaints.
If anything, my main go to cameras are A7 series (own A7 classic, 7S and R II), own many other cameras including DSLR's and it's focus peaking that made me mainly switch to mirrorless vs DSLR, when it comes to manual glass and DSLR, it's not a enjoyable experience, split prism and all.
Speedboosters are for cropped sensors. They won't make .095 lens any faster on FF.
Here they are sprinting (40mm manual lens, focus peaking).
