  • How to get a group all in focus

    I have noticed that I have a problem getting a groups faces in focus usually its just a group of say 6 and the outside two on each end are not sharp. Any pointers on how to do a better job of getting focus?

    Lyn, can you post an example with the EXIF? You might be shooting at too wide an aperture.

        I took a good look at the large version on Flickr, and honestly they all look acceptably sharp to me....however I do need new glasses so perhaps someone else will chime in.

          I might close down a stop or two, those kit lenses are not that sharp as you open up. Also, was this your 18-55 maxed out, or the 55-200 on minimum? These lenses also are not as good pushed so you would be better off using the middle of the zoom range. Try the same shot with the 55-200 at about 100mm an f8 and see what happens.

              the flickr picture is with my 18-55. Ok I'll try that and see if that helps I see that on the recent picture I attached its falls sharp towards the guy on the right (looking at the screen). I dont have the EXIF on that though for some reason lightroom didnt attach it to my flash drive ...

              So for groups I need F8 or larger to get all in focus I guess that would make sense. I love wide open though but for groups i really doesnt make sense. Thanks for helping me think through this.

              Susan, that picture was pretty sharp look at the other one I put on.

                I see what you mean in the second one. Without knowing your EXIF I can't say definitely but it could be that you shot too open - either that or the man on the far right moved and you got a bit of motion blur.

                  So should I just learn to shoot at the F8 recommended by Flea? will that get everyone in focus?

                    There's no magic number for shooting groups. F/8 probably would have been better than a larger aperture, but it's not always appropriate.

                      Find a online Depth of Field calculator and run some numbers. The two primary factors are the aperture and the distance from the subjects. Once you've got some numbers, try some test shots - a bunch of inanimate objects will be perfect as they won't get bored with you making adjustments.

                      Another possibility is that your lens may tend to be softer towards the edges, hence Allan's question about what lens is very relevant. For example, my 70-300mm lens is quite soft and subject to chromatic aberration at the 300mm end so I find that it is often better to back off to about 200mm than to try and zoom in all the way. Online reviews might help but, again, you can test this yourself by taking a carefully worked out series of pictures.
