Focus Points {toggling my focus point}

Q. Which focus points do you tend to use the most often? Do you set a particular focus point and use that for a whole session, or switch focus points frequently?

A. GREAT question! I most often use ‘AF point expansion’ and change the zones continuously using the quick button available on the 7D (see the end of this post for more about that).

Focus is really the most confusing thing I’ve had to learn about my camera. There are SO many factors to achieving perfect focus and this can get really confusing. Lens quality, camera shake, motion blur, focus points, MF, AF, AI SERVO, One Shot AF. All of these can be highly confusing for new camera users. All of what Im about to explain is using my knowledge of the Canon 7D but the principles are the same for most other cameras that have the abilities of the 7D.

{Auto Focus Modes}

Ok so first I’m going to explain the different modes available when you’re shooting in manual.

The screen on the top of the camera looks like this:

If you press the button on the top, that makes all the other numbers on the screen disappear and leaves the DRIVE speed lit and the FOCUS MODES lit. You use one turning wheel (the small one) to adjust one and the bigger wheel to adjust the other. Since I mentioned it, the different ‘drive’ modes determine if you do one click shooting, high speed continuous (holding the shutter button down and shooting up to 8 images per second) or slow speed continuous. Ok so the focus modes. ‘One Shot’ (as seen on the screen above) is good for non-moving or slow moving subjects. You press the shutter halfway down to focus and then the rest of the way down to shoot. The next option as you turn the wheel is called AI Servo. AI stands for ‘Artificial Intelligence’ and this mode uses mathematical algorithms to predict the movement of the subject you’re tracking. I always have my camera in this mode because I’m usually chasing kids around. While holding the shutter halfway down and tracking a moving subject, you’ll see the little focus point squares jumping around allover the screen as the focus continually changes. Press the shutter down the rest of the way when you’re ready to take the shot.

{Focus Points}

Now to the original question about focus points. When you’re shooting in Full Auto, your camera will be using all of the available focus points to auto focus your shot. This can make for wonderfully sharp photos, but you lose all control over what is and isn’t in focus. If you manually select your manual focus point or select which auto focus points to use, you have more control over your image. The first step to accessing this part of your manual settings is to view your screen like this and toggle to the arrowed area:

When you click this box, you are presented with 5 different focus point options. The first is ‘Manual Selec.: Spot Auto Focus’:

In this mode (see the photo left) you use the small and larger turning wheel to move the focus point around on the screen. Then when you are shooting through the viewfinder, you will see a little box in the chosen location. You can then be sure that whatever that spot is focused on is what will be sharp as a tack. This mode is useful for adults who aren’t running around, portraits where you want to be sure that the focus is on the eye or whatnot. Also useful for product photography or photographing the same thing over and over. For photographers like me, I would be most likely to use this for those baby head shots, sharp as a tack newborn shots of the feet with everything else out of focus, etc. And if you’re a strictly 1/3rds guy or gal, you can set your spot to accommodate for that. This mode isn’t useful when you don’t have control over what you’re photographing because there’s no telling where your subject will be from one moment to the next. If you are a total control freak and HAVE to know what spot is in focus AND you have lightening fast manual settings skills, you can constantly change your focus point.

The second mode is called ‘Manual Selec: Single Point Auto Focus’. This works exactly the same as the above explanation for the first mode which is similarly named. The difference is that Single Point AF has a slightly larger area of focus. So where the above mode (SPOT point AF) can produce pin-sharp results, it can be very hard to maintain focus between pressing the shutter half-way and all the way. Use this Single Point mode if you want to manually select your focus point but have a bit of an easier time achieving it. See the first mode explained above to see how Single Point AF mode is useful. Please note that focus points can be changed mid-shooting. See the end of this post for how to do that.

p

The third mode is called ‘Manual Selec: AF point Expansion’. Manual AF point expansion is such a useful mode. It allows you to manually choose any one AF point to be the primary focus, but also makes additional surrounding points active, useful for sports photography and other moving subjects. This means that you can focus on the middle of a portrait subject’s face while also knowing that the area around is also focused. In this mode, you do still need to use the wheels to choose where the points of focus will be placed.

The fourth mode is called ‘Manual Select: Zone Auto Focus‘: This Zone AF mode is only available on the 7D. It allows you to select a cluster of focus points (middle, left, right, upper, lower). This is a great option for most types of photography and is great for a beginner who is concerned about poorly focusing an important shot.

The fifth and last option is called ‘Auto Select: 19 point AF’. This is the mode used by the camera when in full auto, although as we see here, it’s also available to us when shooting in manual. This allows the camera to use any of the available 19 focus points to focus on what IT thinks is the subject you’re photographing. This can be tricky for more creative photographers and I wouldn’t recommend using it if you want to have total control over your images.

{Some stuff I think you should know}

I so so with that everyone reading this shot with a 7D like me. I hate that I’m sharing information that might not be exactly the same for every reader. But if you know your settings and your camera’s inner brain pretty well, you should be able to find most of the options I’ve spoken about within your camera’s settings menus.

So here are a few cool things I’ve discovered about focus points and my 7D.

Changing your focus points while shooting

While you are shooting through the viewfinder, you can move the focus points you’re using without going into the menu. You very simply press this button and then move the focus point around with your turning wheels. Easy!

Checking your focus after you take the shot

In the main menus, there’s an option to display a red square on the main point of focus when viewing your images on your camera’s screen. This way, I can take a shot and quickly look down to be sure that the focus is where I wanted it. You can access this by selecting menu –> navigate to the second blue icon —> AF point display –> enable. Again, this makes a red square display at the main point(s) of focus when viewing the image on the camera’s screen.

    Thank you so much for answering my question! It was really helpful, can’t wait to start experimenting.

  • Lisa

    Thank you for this tutorial! It’s very helpful. It’s been almost a year since I’ve had my 7D. It took me awhile to get used to 7Ds Focus Points. This tutorial is awesome!
    Thanks again!

    THANK YOU! Everyone thought I was nuts because I was confused about this…I shoot with a 30D and this works for me except for the Monitor part..mine’s a little different. The explanation of the Focus Points was something I wasn’t even aware of…will play around with those more…THANK YOU!!

  • Brittany

    This is great! I didn’t realize what a beast focus is until I shadowed a photographer at a couple weddings, and many of my pics were focused in all the wrong spots :( I definitely need practice, practice, practice! My question now is, and maybe it’s totally dumb: when shooting portraits of more than one person in a shot, how do you achieve focus on all of their eyes/faces, if they are not on the same plane? Do you just have to pick the most important person in the shot? Or do you throw that ideal focus out the window?

    Thanks, Elizabeth!

  • elizabethhalford

    @Brittany: When you choose your focus point, that’s where the focus will begin. The more open or closed your aperture is will control the spread of focus from that point. For groups, use a higher aperture (exe: f/5.6) so the focus can spread. if you were going for a shallow depth of field with background blur, you might want to paint on some blur with Photoshop. I use a paint-on-blur action from MCP Actions for that. Ever so slightly, though, or it will look really fake! Hope that helps! :*)

  • Brittany

    Thanks so much, Elizabeth! And great photoshop tip… yes, love the background blur :)

    VERY helpful…. THANKS!!!!

  • Kristin

    Thank you so much for sharing your knowledge.  I’ve had my 7d for over a year now and feel like I learn something new about it all the time.  I have a question.  When I go to my Quick Menu and select the focus selector and turn my dial, I’m only given 3 options (19 pt, Single pt, zone AF).  When I press the button in the middle of my dial when on the focus selector, it does show me the other two options, but no matter what wheel I turn or if I use the toggle button, I can only choose the 3 points mentioned above.  Do you know if there is something in settings I need to adjust to have access to the other 2 options?

    Thanks for the great information.  I tried this out and realized that when checking the focus after taking the shot, it only tells me which focus point was on, not truly which part of the picture is in focus. I tend to hold the shutter half-way to focus and the re-frame my picture, so this doesn’t really work for me.  I guess I was hoping for too much – now that would be a smart camera!!!

    Hmm…my post didn’t work. Anyway – @ Kristin did you find what you need? You have to activate the other two focus options in the Custom Function settings of your camera.

  • Diana C.

    I also had to deal with this when I tried to get AF Point Expansion. I had to get my manual out and go into the custom function settings and “register” it before it could be activated. It took me a good while to figure it out.

  • Mike

    Hello,

    Very good information. Unfortunately I do have such an advanced camera that supports selecting different AF points. My question is that is there any co-relation between the AF point you select and where the light meter reading is taken from? Does the camera read the light from the AF point that is lit up?
    I have a Canon XS dslr camera.

  • Tina

    Thank you for this.  I just purchased the 7D and its a bit intimidating.  I changed my settings around for an indoor basketball game and got a much better focus than last game on the settings I thought was correct.  Thank you!

  • Christy

    This article just solved every remaining question I had about my 7D focusing. I didn’t even realize I had 2 extra focus modes to choose from! and in the process of activating them I learned how to set and did set all of my custom functions! I’m so excited right now I could squeal! 

  • Dana M

    I love that you shoot with a 7D as well!  This post was very helpful as I have had some issues with focus, though I think that with your tips I can improve.  Thanks for continuing to share your experience and knowledge with the rest of us via your blog!

  • Lotharpanzer

    Girl- I just wanted to tell you that your site is great. I am a consultant as a profession and I agree with your approach- simplified details. Beyond that, you have a clean and in-depth delivery limited to that which is pertinent. 

    Thank you.Congrats. Please keep’em coming. 

  • Dawn

    SO helpful. I’ve always struggled with focus. I have a big job tonight, and I know this information will help me immensely. Thank you for sharing your knowledge!
