Join Steve Simon for an in-depth discussion in this video Understanding group-area autofocus and the 5 points, part of Performance Tuning the Nikon D800 and D810.
- There's a new Group Area Autofocus Mode…that's on the D810, but the D800 doesn't have it.…You know, it's a welcome addition…for sports and action shooters.…It was introduced to help eliminate the problem…of back focus with very moving,…very fast moving subjects.…You know, when you've got a very fast moving subject,…like in sports or wildlife situation,…you often have very little time to aim and compose.…This is where Group-area AF can really shine.…In Group-area AF, the camera uses a 5-Point cluster.…
Any of those five points can be chosen by the camera…as the priority sensor.…In Group-area, it uses the Closest Subject Priority,…which means that when you aim the 5-Point cluster…over your fast moving subject, it chooses the one point…that's closest to the camera to focus on, as your…priority sensor, and this helps reduce back focusing,…where you end up having the background in focus…and not the subject that you wanted to be sharp in focus.…
So, the dynamic modes work really well,…but, with Dynamic 9 or 21, there's just one priority sensor,…
