Depth of Field (DOF) and Hyperfocal Distance
You may have wondered "How do pros make those wonderful landscapes where everything seems to be in focus?" Well, it is not merely by closing down the aperture of superb wide angle lenses. 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 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 105mm. Also, the smaller the aperture you use the bigger the depth of field; i.e. in any given focal length lens, one gets more depth of field with it at f/16 than at f/4, for example. You may want to check a most practical and well illustrated guide on the subject of DOF and aperture here.


The Circle of Confusion (CoC) has nothing to do with other camera brand users. It is the largest onfilm or onsensor circle that you can see as a well defined point on an 8×10 print at arms length; that is, when viewed at from a "normal" viewing distance of 2 to 3 feet. 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 circle is 0.025mm. Often rounded to 0.03, the exact number used here is 0.02501. For the Nikon DX (APSC) digital sensor format, the number used here is 0.0200.
The calculator in the next page allows for you to use any CoC of your choice, via a drop down menu.

These two sample images were shot at f/16. The one on top was made focusing at infinity, the image below was produced with the lens focused at its Hyperfocal Distance.
Take notice of the sharpness of the bush on the right hand side of the frame and the expanded DOF all the way to the horizon when using Hyperfocal Distance. 

Please forgive me the decimal fractions in the table below for 35mm film and Nikon FX format. It is hard enough to approximately 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 from the formulas are pretty accurate for wide angle lenses.
For typical wide angle lenses on a DX format Nikon or Fujifilm Digital SLR, you may download a table here for your bag.
For other focal lengths or apertures, both DX digital and FX film, you may use the H & DOF calculator
Try not to use the smallest aperture in your lens (f/22, f/32) to avoid diffraction  a sharpness killer.

"Ok. Now that I know the number, how do I set that Hyperfocal Distance on my lens?"
The short answer is: you don't. Modern lenses don't have room in their barrels for the set of markings required, specially superwide 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.

The Formulas
You may want to understand the relationship of the variables or make your own computations, so below you can find the equations.

Hyperfocal Distance
As mentioned before, setting focus at H, the Hyperfocal Distance, gives maximum depth of field from H/2 to infinity.
H = (L x L) / (f x d)
Where:
H  =  Hyperfocal Distance (in millimeters)  
L  =  Lens focal length (i.e. 24mm, 28mm, 35mm, 45mm)  
f  =  Lens aperture fstop  
d  =  diameter of circle of confusion (in millimeters)  

NEAR FOCUS LIMIT
This is the distance from where acceptable focus starts, when you focus at a given distance, whether that distance is the Hyperfocal or not.
NF = (H x D) / (H + (D  L))
Where:
NF  =  Near Focus Limit (millimeters) 
H  =  Hyperfocal Distance (in millimeters, from above equation) 
D  =  Distance at which the lens is focused 
L  =  lens focal length (i.e. 24mm, 28mm, 35mm, 45) 
FAR FOCUS LIMIT
This is the distance where acceptable focus ends, when you focus at a given distance, whether that distance is the Hyperfocal or not.
FF = (H x D) / (H  (D  L))
Where:
FF  =  Far Focus Limit (millimeters) 
H  =  Hyperfocal Distance (in millimeters, from above equation) 
D  =  Distance at which the lens is focused 
L  =  lens focal length (i.e. 24mm, 28mm, 35mm, 45) 
DEPTH OF FIELD
The distance between the farthest and nearest points which are in focus
DOF = FF  NF
Where:
FF  =  Far Focus Limit (millimeters) 
NF  =  Near Focus Limit (millimeters) 
Notes:
 Circle of Confusion diameters used here are based on acceptable sharpness
while viewing an 8x10 inch print at arms length.
 Multiply inches by 25.4 to convert to millimeters.
 Divide millimeters by 25.4 to convert to inches.
 True fstop value of apertures was used in the calculator as per this table:
f/1  f/1.4  f/2  f/2.8  f/4  f/5.6  f/8  f/11  f/16  f/22  f/32 
1.0000  1.4142  2.0000  2.8284  4.0000  5.6568  8.0000  11.3137  16.0000  22.6274  32.0000

Sr. Garza, Ya encontre la respuesta a mi pregunta!
Olga Celle (CatLady51) on October 17, 2014
Dear Mr. Garza, My question is in regards to the hyperfocal distance. How do you do it in the practical on the ground practice? I just used the formula for my FX 1424, it tells me 2 meters. Sometimes, one does not have a measuring tape to go to measure 2m. Moreover, often one is at the edge of a hill...So, a friend of mine suggested to make the measurement at f/8 for 2 meters and mark the lens body with a white pen...But then comes another problem, if we are doing, say, a long exposure, we often change the f/ So...how do you it? 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.
Michael Shake (Mike_Shake) on February 21, 2014
Opps...my bad. I see now that the MM is for the focal length only. Still wondering where to measure the distance from.
Michael Shake (Mike_Shake) on February 21, 2014
The link works but I found a mistake on the DX format 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?

Great info...but I'm having trouble downloading charts. Am I overlooking something that needs to be done? Tolya

Thanks for the article. The links to the pictures and PDF seem to be broken. Can you update the links? Thanks Tom
