To take a series of bracketed shots, prepare your composition and focus on the part of the subject nearest to the lens by half-pressing the shutter button. You will soon notice that the shooting mode has automatically shifted to High burst/silent and cannot be changed as long as focus bracketing is active. Simply enter the menu and turn all the options to ‘on’. How does the Focus Bracketing function work?įocus bracketing, like the other bracketing options, can be activated from Shooting Menu 2. I’ve found that a focus differential of 5 tends to work well for most close-up work, but I will use lower values if there are many small details or intricate patterns in my composition that would be hard to reproduce in post production with a cloning tool. The important thing is that each shot overlaps the depth of field of the previous shot. (The images have not been retouched.) In the “10” example, you can clearly see some blurry banding where the focus hasn’t been captured. However, you don’t want to use a focus differential that is too low (1-2) unless absolutely necessary, as you will wind up dozens of shots that barely differ from one another.īelow is an example of the difference between a focus differential of 5 and 10. These will appear as out-of-focus bands in your composite image. With a higher focus differential (8-10), the distance between each shot is wider, so it is more likely that you’ll end up with gaps between the in-focus areas of your image, especially if you use a very fast aperture. The focus differential is the distance between the in-focus areas in each shot.
