is based upon the properties that I have already discussed. Recall that everything fromhalfyour hyperfocal distance until infinity is in focus; so, to find the hyperfocal distance for a given scene, you can simply double the length between your lens and the closest...
Once you have the information, you need a lens with a depth of field scale on the barrel to tell you the distance at which the lens is focused. Many lenses have these, but some don’t (including lots of kit and pancake lenses). Distance scales aren’t precise, so be prepared to wor...
If the lens is set to focus on infinity (the infinity mark is over the central mark on the depth of field scale), then you only need to read off the distance value for the f-stop mark to the left of the central depth of field scale as everything between it and infinity will be ...
Or for two lenses, you can enter another distance for lens B, or another choice, it can compute an equivalent distance (for the B lens, matching the A lens Field of View) from the focal lengths (as described here). Note that the initial loaded default is a 50 and 200 mm ;ens both...
Older lenses are great for explaining hyperfocal distance, so let’s start by looking at one of them. Lenses from the film days typically have a scale printed on them that allows you to measure what distances are acceptably sharp at a given aperture setting. For example, take a look at th...
At top is the distance scale (on the lens' focus barrel) showing figures in feet and meters (this also shows the infinity position).Below that are a set of lines beneath which are the f-stops of the lens. This is the depth of field scale. For each f-stop, there are two ...
