I notice when using an AUTO AF it highlights multiple AF points to keep in focus. In manual you can only choose one that I am aware of. Now am I able to choose more then one AF point in manual? Also, I heard that some photographers take multiple shots with different AF points to have multiple areas in focus then put them together? How is this achieved if what I say is true?


--thank you =)

You can choose auto AF point selection in M mode too, just push the AF point selection button and turn the wheel until all of the points illuminate on the LCD diagram.

BTW, pretty sure this is covered in the manual ;)

When you say "manual" what do you mean?

M on the mode control dial? If so, that's only for exposure and not AF, and in that case you can chose individual AF points or let the camera chose for you (full auto AF).

If by manual you mean manual focus (M on the lens barrel switch), then AF is disengaged and you can only focus by using the focus ring on the lens.

Finally, if by manual you mean individually selecting the specific AF sensors by use of the Quick Control Dial or the Multi-controller toggle, then no, you can only manually select one AF point at a time.

Some macro photographers take multiple shots with different points of focus (not necessarily different AF points) and then use a process called "stacking" to achieve a simulated depth of field that would be greater than that achieved with a single photo. You might ask this question in the Macro Forum to get a better answer since I've never used the process but only heard it described.

THE MANUAL IS THE BOOK THAT COMES WITH THE CAMERA> AKA THE OWNERS MANUAL!!! Geezzz


Please speak slowly and distinctly. I have a wife, AND a computer, I don't need any more confusion in my life.

I wanted to be a nude photographer, but when I went outside naked, everyone pointed and laughed, so I gave it up.

No.

As said before: different points of focus, not necessarily different focus points.

Do a google on 'focus stacking'.
