Thread: How to check focus

    Default How to check focus

    Just wondering how do you check if your DSLR has focused on the right portion?

    The viewfinder is so small and even on autofocus, you can't really tell which parts of the photo is in focus. You can only tell if the photo is in focus when you are viewing it after. For scenery this is still ok, but for sports/action/portrait photos the moment would have been lost if you don't get the first shot in focus.

    Anyone got any tips on this?

    ........ I was half Rashkae expecting you to say RTFM

    TS.... look up your cam's user manual and look for something called Depth of Field Preview/Button/Function ..... it will show you DOF at the f-stop used (and by default what is in focus in the viewfinder before u release the shutter)

    ........ would'nt hurt too to study the DOF charts for the various focal lengths too..... google it, this is a good skill even if you remember them as rough ballpark figures......... the newer charts have DOF charts for the various crop factors too

    Read up about the AF system, how it works. From this you can see how to support the AF system so that it locks on the correct part and how to avoid distractions. But as night86mare mentioned: there are cases when you can't use AF plainly.
