Could someone tell me on the Nikon D70 while shooting in continuous mode at 3fps, does the lens refocus between each shot? Do you need to have AF-C set during continuous shooting?

Thanks.

In AF-C, the camera focuses continuously while shutter-release button is pressed halfway. Photographs can be taken whether or not camera is in focus (release priority).

In AF-S, the camera focuses, beep sounds and in-focus indicator appears in the viewfind er. Focus remains locked while shutter-release button is pressed halfway. The shutter can only be released when the in-focus indica tor is displayed (focus priority). If the subject stops moving before shutter is released, in-focus indicator will appear in the viewfinder and focus will lock at this distance.

If the subject moves, focus will be adjusted to compensate in either AF mode.

On top of what dcrawley mentioned, there's 1 important difference between the two modes when used for continuous shooting:

In AF-S - the next image will only be taken when the camera deems the subject at the selected focus point is in focus (hence shooting continuously may slow down from 3FPS).

In AF-C, the sequence of images will be taken at 3FPS (or thereabouts) regardless of whether the lens had time to focus on a (presumably) moving target.



NB: it pays to have long exposure noise reduction turned OFF if you intend to use the camera for continuous shooting. With it on, you get no more than 1.5FPS.

One follow up question. Is it suggested to have the "Dynamic Area" focus set when shooting in continuous mode rather than Single Area or Closest?

Thanks very much for all your previous input, it helped a great deal.

Use "Dynamic Area" when following erratically moving subjects and in other situations in which it is difficult to keep the subject in/near the selected focus area (fireworks for example). You will not see your selected focus point change in the viewfinder.

Use "Single Area" for relatively static compositions with subjects that will predictably stay in selected focus area. Also recommended with telephoto lenses or when subject is poorly lit.

In my experiences shooting my son's t-ball games that Single Area is better. If you have trouble panning the camera focus point as the same speed as the object or are just off enough, Dynamic can render some of your shots OOF. Closest subject is not an AF mode that I use ever; I feel I lose too much control.
