Hyperfocal Distance Calculator

Great! But where on the page is the calculator?

Anyone know of such a calculator for my PocketPC PDA?
 
I saw the word "hyperfocal" between those nicely coloured lines but it's not a link.

Maybe XP (SP2) blocks it...?

PDA? We are getting too weighed down by electronic stuff in this world. No wonder more people are injured by lightning strikes than by any other natural phenomenon.

Distance only in feet? What are those? :)
And only from f5.6?

Rover, you're right about the electronic gadgets but I actually use my PDA quite often.
It holds documents from work (for when I am on standby duty), mp3s for when I'm traveling, photos that I can show to people, and a slew of e-books also for when I'm traveling.
For me my PDA actually saves me space and weight.

I wonder how no one mentioned how PDAs can actually be put to very good use by photographers.

I have a Palm Pilot, and I have a whole bunch of photo aids there - various programs that make life a bit easier, and it's a plus to have all that data in one place - and I can always export that data, print it out, etc.

My most useful PDA programs:

1) Foto Timer (see my Web site - "Palm in the Darkroom" link) - excellent program to use in the darkroom, for timing development, etc. I also use it for printing, and it also drives my englarger. Basically, once I press "start", everything is automatic - I just have to move paper from the easel into the trays....
Naturally, I also use it for neg development.

2) Photo Log (from the "Photographe" suite of programs) - for logging and calculating exposures when I do MF work.

3) pCAM - for hyperfocal dist. calculations, etc.

And there are others, but I just don't use them that often.

I never understood why is there a need for such a "calculator"... Seriously... isn't that much easier with the DOF scales on the lens (and you can decide to "cheat" if you find them too optimistic, i.e. use the f/4 scale for f/5.6 aperture) ?

Of course, you don't always HAVE a dof scale on the elns...that's true.

I have attached a scan of my Hyperfocal DOF calculator. I also have it in a smaller version, inserted into the film box tabs, on the back of my Nikon SLR's. In that way, when I am shooting serious SLR work, it's always right there for my perusal. I don't see why you can't tape one to the back of a RF. Throughout the last couple of decades, I have also found that you can get fairly accurate DOF by using the 1/3 to 2/3 focusing rule, and by stopping down to a small aperture. Has worked fine for me for a couple of decades or more. Once you've composed the shot, just focus on an object that is 1/3 from the bottom of your image. Then stop down, and fire away. Lenses have 2/3 more distance in focus behind the focal point, as opposed to just 1/3 in focus in front of the focused point.

Hope this helps

These are handy guides. Every lens I've ever owned has had the scales on the barrel and I've come to rely upon that. However, one that I bought a few years ago does not. It is quite wide so it has not been a problem, but it's still good to know exactly where its range of focus is. Thank you for providing them.
