To use the charts, just line up the focal length and aperture settings you plan to use. The corresponding figure will be the hyperfocal distance. The top chart is in . They maximize DOF (depth of field), the region of acceptable sharpness, by focusing at the hyperfocal distance. A simple function of lens focal length, aperture. Focusing at the hyperfocal distance will make an image with DOF from half of that The calculator in the next page allows for you to use any CoC of your choice.

You must estimate where the hyperfocal distance lies on the scale. Application of the concept leads to many questions: As mentioned above, however, hyperfocal distance also depends on your focal length. It is common for beginners to adjust the focus to get near objects in focus when they look through the viewfinder. Do I have to atble exactly at the hyperfocal distance?
Also, the smaller the aperture you use the bigger the depth of field; i. If that part of the picture is particularly important, then the very edge of sharpness might not be good enough. You’ve measure the distance by walking the “equivalent” number of steps. The hyperfocal distance equation is derived from the “thin-lens” equation, which assumes a single-element lens with no thickness. Just introduce your camera, focal length and aperture and read the values on the chart.
Let’s see how these rules apply to focusing a lens for hyperfocal distance photographs.
Guide to Depth of Field and Hyperfocal Distance
Contests Updated December 08, Nevertheless, the Hyperfocal Distances calculated from the formulas are pretty accurate for wide angle lenses. This way, you’ll make sure you get all background elements in focus.
But if there is a particular subject in your photo, forget about hyperfocal distance. I see now that the MM is for the focal length only. This is useful if you have several cameras with different LMFs.
Modern lenses now don’t have markings for various distances, so an approximation, or estimate is enough. You have a nice foreground and background in the frame, and you want as much as possible in focus.
DO NOT enter 35mm equivalent focal lengths. Show pages 6 Pages. FAQs jyperfocal What Lens.
The Notes sheet has some explanation about how the numbers were computed. To change it you will need a writable version. Click for the program to.
These tools will show the hyperfocal distance for a lens set to a particular f-number. You can see that a mm lens isn’t useful for taking a landscape photograph in which you want near objects to be sharp. Hyperfocal distance depends on three factors.
How do you do it in the practical on the ground practice? More articles by J. Now that I know the number, how do I set that hyperfocal distance on my lens?
Thanks for the article.

It doesn’t need to be precise. It is not as complicated as the name makes it sound.
