"Focus Indicator When Manually Focusing In Live View"


Aventura, US
          

When I manually focus and look through the viewfinder I get a green dot at the bottom left when focus is achieved. There doesn't seem to be an indicator in Live View. Is that correct?

It's more complicated. First off, turn on live view, focus, and then hit the QUAL + button several times on the right lower backside of the camera. This zooms you in on the image at the point at which focus was achieved.

You know, don't you, that the Phase Detection mode of focus used in Live View is considerably more accurate than the Viewfinder method? But it is also slower. And you can select various methods for focus needed for Video. These included Face Detection.

It is a deep subject, and most of us D7000 don't use it fully so it is easy to forget. But, play around with it in LIve View Mode. Push the QUAL + button, and then zoom out with the ISO - button. It is technologically sophisticated.

That makes sense. I now realize that if you are in Manual Focus, the focus is always achieved (so it wouldn't make sense to have a focus indcator),-it's just a question of where. Right now I'm only interested in still shots. I will play around with it. Thanks for your insight.

Live View gives you many of the tools once available only to owners of a 4x5 View Camera. When I do product photography on a tripod, Live View allows a slow, careful analysis of the composition.

In particular, DOF study is a real godsend. It really is powerful.

The focus indicator in Live View is the Red box that turns Green using AF. When you use Manual focus on the lens or on the camera, the Red box does not change color when the camera achieves focus. When you adjust focus you can magnify the particular subject as Gary said, then you observe how focus changes in the LCD. You decide when the subject is in focus.

BTW, Contrast Detect autofocus is used in Live View.

TXstone, you are right. Live View uses Contrast Detection for autofocus. A red square when it's hunting for focus. Turning to a green square when focus is achieved.

And I made a mistake about the location of the zoom button. The Qual button (marked with a +) is on the lower left back of the camera body. By repeatedly hitting the +button, you can magnify portions of the image up to x32. And you can navigate around the image by rocking the Multi-Selector wheel next to the LCD.

A 32-power magnification certainly is proof of focus.
