Re: Hyperfocal distance and circle of confusion in metadatafile of Pentax K5 and K1

I agree with you fully. But still it is fun for me, thinking of possibilities to make the focusing process more intelligent, meaning faster and more accurate, but not more accurate than needed. If the system knows the depth of field, it can take the allowable error into account and optimize

Re: Hyperfocal distance and circle of confusion in metadatafile of Pentax K5 and K1

I don't think the camera knows the minimum focus distance on any lens that doesn't have that data on it's chip. So it's only available for some F series lenses and later. It might also be available from the A lenses supplied with the MZ/ZX-M I think there were two lenses that were pretty

Re: Hyperfocal distance and circle of confusion in metadatafile of Pentax K5 and K1

The metadata also shows the minimum focus distance. How can the camera know, even when it does not know which lens is mounted? Only the lens can tell the minimum focus distance. But if the camera knows the minimum and maximum focus distance, than it could estimate the focus distance! Is

PDAF systems in particular MUST know absolute lens focus setting in order for the AF systems to work. Without it, there's no way to calibrate the system. G > On Jul 17, 2016, at 9:11 AM, Larry Colen wrote: > > I wish the lens mounts would return focus distance to the camera

Going through the metadata of K5 and K1 files I observed that the hyper-focal distance is available, based on the applied aperture and focal length. Wouldn't it be nice if this info was visible on camera for manual adjustment, or even better an select-able auto focus mode with hyper-focal
