With all of the advances in digital cameras and features, I often wonder why a manufacturer can't add a mode for auto hyperfocal distance? It seems that the camera already has the information to calculate it, i.e. f-stop & lens focal length. Would out it be too difficult to program the camera/lens to allow a press of a button in this mode and the lens would focus at the hyperfocal distance?

Interesting idea.

Canon 20d already had something similar: a mode where you focus first on the closest point, then focus on the farthest point, and the camera calculates the f/stop to keep both points sharp. It was abandoned in later models, and I do not know why. Some other great ideas, like eye focusing, from film days, Canon abandoned as well.

Probably because everyone has a different idea of 'acceptable sharpness'. I find the 'standard' definition of a circle of confusion of 30 microns on a 35mm sensor to be rather blurry, and usually go for a circle of confusion of two photosites' side length instead.

30? surely that is wrong with 5 micron pixels. Do you mean 3?

No, 30 microns is the 'standard', but is really based on early film cameras, and small prints.

I had completely forgotten that feature on some Canon cameras. In my humble opinion it was very cool and I used it often.
