- Well, when dealing with moving subjects,…Nikon has a very effective AF system called dynamic area.…It comes in three basic flavors:…D9, a 9-point array,…D21, a 21-point array,…and D51, which is a dynamic mode…that uses all 51 points the AF system.…If you have a D800 or D800E,…and set your autofocus to dynamic 9 or 21,…in the viewfinder, you're just going to see…the priority sensor,…so it's a little bit of a leap of faith to know…the arrays surrounding that priority sensor.…
But with the D810, they kind of fixed that situation.…If I go into the menu,…and go into autofocus, a5,…you'll see focus point illumination,…and dynamic AF display.…When you turn this on, when you're in dynamic mode,…in the viewfinder, you'll not only see your priority sensor,…but you'll see the 9- or 21-point array,…which lets you know that you're actually in dynamic mode,…which is kind of nice.…
So the dynamic area systems are designed…to help keep moving subjects in sharp focus.…It only works in continuous-servo mode,…but we're back-button-autofocusers,…
In this course, photographer, author, and educator Steve Simon demonstrates a set of customization strategies aimed at making the D800 and D810 far more responsive.
