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 may have wondered “How do pros make those wonderful landscapes where everything seems to be in focus? They maximize DOF depth of fieldthe region of acceptable sharpness, by focusing at the hyperfocal distance.
A simple idstance of lens focal length, aperture and the diameter of the Circle of Confusion. The wider the angle of a lens, the shorter its focal length and deeper depth of field. So, as an example, an 18mm lens will have deeper longer depth of field than a mm. Also, the smaller the aperture you use the bigger the depth of field; i. You may want to check our articles on the subject of DOF.
The Circle of Confusion CoC has nothing to do with other camera brand users. Anything larger is seen as a small circle, not a point and is therefore perceived as out of focus. For 35mm film and FX format the diameter of such tagle is 0. Often rounded to 0.

The calculator in the next page allows for you to use any CoC of your choice, via a drop down menu. The one on top was made focusing at infinity, the image below was produced with the lens focused at its Hyperfocal Distance. Please forgive me the decimal fractions in the table below for 35mm film and Nikon FX format.
It is hard enough to tab,e set any distance on a lens. As long as it is close, it will look good. However, bear in mind the formulas were derived for the ultimate theoretical simple lens, not the sophisticated zoom and telephoto lenses we now use. Nevertheless, the Hyperfocal Distances calculated dixtance the formulas are pretty accurate for wide angle hyperfocql.
The online hhyperfocal below let’s you calculate the depth of field and hyperfocal distance. Now that I know the number, how do I set that hyperfocal distance on my lens? The short answer is: Modern lenses don’t have room in their barrels hypertocal the set of markings required, specially super-wide angle zooms. So it is best to estimate the distance, focus there and lock it. As long as your are approximately there, you’ll get great results.
That is how all of the samples in these pages were accomplished. Select your lens focal length mm. Enter the focusing distance. For that distance, Near focus limit of DOF: For that distance, Far focus limit of DOF: The true f-stop values of aperture were used in the calculations as per this table below:.
You may want to understand the relationship of the variables or make your own computations, so below you can find the equations. Near focus limit NF This is the yhperfocal from where acceptable focus starts, when you focus at a given distance, whether that distance is the Hyperfocal or not.
Far focus limit FF This is the distance distwnce acceptable focus ends, when you focus at a given distance, whether that distance is the Hyperfocal or not. Depth of field DOF The distance between the farthest and nearest points which are in focus. Download these files for your bag. Our big thanks again to Don Fleming of dofmaster. Have a great time!
The fog has lifted! They said and I’ve also read this elsewhere that I should use their DoF table at two F-stops more critical ie: I should have asked why they didn’t produce a correct FX DoF table in the first place, but it’s possible I suppose that this could be their table for DX.
It suplies area in focus,minimum to maximum and overall focus area along with hyperfocal focus point and even a custom sensor size option. With distance infomation already used by the camera as part of exposure indicting which focus points are in focus and flash exposure distance. One extra menu item and the ability to programme a button gives a modern and more acurate solution ,the hyperfocal area could even be indicated using the focus points on the view finder display.
This is terrific info! To change it you will need a writable version. If you have a Google account you can save to a local copy for editing. If not, you tabel download to Excel format. You will see a sistance menu for CofC cell A1 and tabel format cell B1 on the first sheet I couldn’t figure out how to combine these selections into one.
I created sheets for English and Metric units combined and for each individually and formatted the text to print to a nice wallet size. The Notes sheet has some explanation about how the numbers were computed. I hope others find this useful. Feel free to post this on Nikonians as you see fit. I’ll also post this in one of the Forums.
Modern lenses now don’t have markings for various distances, so diwtance approximation, or estimate is enough. It doesn’t need to be precise. I believe it is mentioned in the article. In the Landscape forum you may find many examples of this practice. Garza, My question is in regards to the tavle distance.
How do you do it in the practical on the ground practice? I just used the formula tagle my FXit tells me 2 meters. Sometimes, one does not have a measuring tape to go to measure 2m. Moreover, often one is hyprfocal the edge of a hill Thanks in advance for your response. Michael, You made me smile with your question. The tables are made for a single element perfect lens, not for modern lenses; so any approximation should suffice for good results. I see now that the MM is for the focal length only.
Still wondering where to measure the distance from. The link works but I found a mistake on the DX hyprfocal for the feet. Although it says feet at the top on the chart it has “Lens Focal Length mm ” on it. I know it’s approximate but where would you measure on the camera for the distance, from the front of the lens or the mark on the camera body for where the sensor is?
Am I overlooking something that needs to be done? Thanks for the article. The links to the pictures and PDF seem to be broken.

Can you update the links? Thank you for the DoF calculater as it is very usefull for especially Nikon prime lenses.
Take notice of the sharpness of the bush on the right hand side of the frame and the expanded Hyperfocap all the way to the horizon when using Hyperfocal Distance. Click for the program to. You need to enter a focusing distance any for the calculator program to compute the Hyperfocal Distance, which is independent of the focusing distance you enter.
If you don’t select a Circle of Confusion value for an specific camera model, the calculator will use the most recommended one for the format you select; either DX or FX.
