I am looking for a website that lets you build and print a custom hyperfocal chart for your lenses. I had used the one at www.johnhendry.com in the past. Now when you go to that website and use the chart generator it flashes the screen and resets the chart. It seems to be down, and has been for a few months.

Anyone know of a site where this can be done and printed?

Nevermind. I found the mathematical formulas online and made my own in Excel.

OR... (assuming you have an iPhone) go into the app store and search for Field Tools

Many applications only work where you get cell service. That's why I wanted something old school.

There are also a number of Excel spreadsheets freely available for download, though you might have to watch out for gigo in their case.

This is exactly why I made my own. I am pretty sure the formulas I used are correct, and it is easy to customize for different CoC, lens focal lengths and apertures.

So for a 100mm lens @f8 the theoretical ideal focal point is 42m away for depth of field
......Am I understanding this correctly?

The "hyperfocal distance" is 42m away. That's not necessarily the same as the "ideal focal point".

The hyperfocal distance represents the distance at which everything from half that distance to infinity will be in acceptable focus. In this case, from 21m to infinity. This concept is based on the "circle of confusion" which represents how much out-of-focus (OOF) you can tolerate while the result still looks acceptable. The diameter of the circle of confusion (Dcc) is related to the photo's original format size (i.e. FF DSLR, m43, medium format...), the size of the image that is being viewed (e.g. 8" x 12" print, 27" monitor, 20" x 30" poster...), and the distance from which you're viewing the image. IOW, it's based on magnification. The value of Dcc = 0.03mm represents an original image of 36mm x 24mm (i.e. full frame DSLR), printed at 8" x 12", and viewed from three or four feet away. If you get a lot closer, you'll notice that some areas that appeared to be in focus from "normal viewing distance" now appear slightly OOF. Many people, including Harold Merklinger (see below) say that if you want infinity to be in focus, then you should focus at infinity.

Merklinger, "The INs and OUTs of Focus" http://www.trenholm.org/hmmerk/TIAOOFe.pdf

BTW, many older "Alt" lenses (and some newer ones, too) have hyperfocal distance markings on them. For example, the Leica Summicron-R 50mm f/2 lens shown below is set at f/8 (aperture values on bottom ring with white dot "index" just above), and the ring of aperture values just above the index shows the range of focus distances (next ring up) that are "in focus". In this example, the lens is focused to 10m (or just about), and the left and right values of 8 on the hyperfocal scale show acceptable focus from about 5 m to infinity.

While maybe a pipe dream, it sure would be nice to see the big two provide this on some of their more popular lenses. Leica had it right some time ago

Okay, I get it now
Thanks for the explicit and easy to grasp clarification
