Free 5DIII Info
Many folks have e-mailed asking how to set up rear focus on the Canon EOS-5D Mark III. It is a bit hidden in the extensive Menu/Custum Functions screens. Here’s how you do it:
The last item on the 2nd Custom Function (C.Fn3: Display/Operation–Orange) Menu is Custom Controls. Select Custom Controls by scrolling down with the thumb wheel and then hit Set.
The first item in the left hand column is Shutter Button half-press. The default there is Metering and AF start. With the orange outline around this first item Press Set. You will see the orange outline around the Metering/AF symbol. Turn the thumb wheel one click clockwise that the orange outline is around the metering (only) symbol. Now press set again.
Next, scroll down to the second item in the first column, the AF-ON button. The default there is Metering/AF. Press set and turn the thumb wheel one click clockwise so that the orange box is around the * (exposure lock) symbol. Now press Set again. Only one more to go. Turn the thumb wheel one click in the clockwise direction to highlight the * button. The default there is the * button, i.e., exposure lock. Now press the Set button, turn the thumb wheel clockwise one click so that the Metering/AF symbol is outlined in orange. Press Set one last time and touch the shutter button lightly to exit the menu screen and you are good to go.
Metering will become active when you press the shutter button halfway but the camera will not focus. (That’s what rear focus is all about.) Focus by pushing the star button–the second button in from the upper right back corner of the body. And release the shutter button to create an image by fully depressing the shutter button. On the rare occasion that you need to lock the exposure you will use the AF-ON button as we have effectively switched the functions of the AF-ON and the star buttons.
When using rear focus you want to be in AI Servo AF all the time. You have One-Shot AF available by pressing the star button to set focus. You can then release the star button and recompose. To follow a swimming, walking, running, or flying bird simply press and hold the star button. In either situation, simply press the shutter button fully to create an image or press and hold the shutter button down fully to create a series of images. Remember: if you lift your thumb off the star button the AF system will stop tracking.
Two years ago I went to rear focus full time with all camera bodies and have never looked back. You can read the original rear focus tutorial here.
This is the type of information that will be available in spades in the upcoming EOS-5D Mark III User’s Guide. I hope to have it completed in one month but may be offering a pre-publication version at a discount soon.
This image was created with the Canon 70-200mm f/2.8L IS II lens and the 1.4X III TC (hand held at 115mm) with the Canon EOS-5D Mark III. ISO 400. Evaluative metering + 1/3 stops: 1/800 sec. at f/6.3 in Manual mode.
Central Sensor/AI Servo Rear Focus AF and re-compose. My elbows were braced on the railing to ensure that the lens did not move in relation to the subject after focus was set…. Click here if you missed the Rear Focus Tutorial. Be sure to click on the image to see a larger version.

Canon 70-200mm f/2.8L IS II lens. Man, I am loving this lens on my shoulder with the 2XIII teleconverter. I also use it a lot–depending on the situation–with the 1.4X III TC.
Canon EOS-5D Mark III. Man, I am in love with this camera body. Both the files and the AF system are superb. I cannot wait to get to Morro Bay.

The Lens Align Mark II. I use the Lens Align Mark II pretty much religiously to micro-adjust all of my gear an average of once a month and always before a major trip. Enjoy our free comprehensive tutorial here.
