Title: Focus Range Index
Post by: k31thw on November 22, 2022, 03:27:18 PM

The EXIF info for NG files taken on my Pentax K3 has a tag "Focus Range Index" with values of:
0 (very close)
1 (close)
2
3
4
5
6 (far)
7 (very far)

Is there any way to estimate the distance to the subject? I'm not looking for pinpoint accuracy, just a reasonable estimate. FWIW I use a Sigma 17-50mm and a Sigma 70-200mm.

Thanks

Keith

This really depends on the K3. You could do a series of test shots, but I'm guessing that the conversion will be lens-dependent.

Thanks for the quick response Phil.

Being a lazy old bugger I was hoping I wouldn't have to actually do any work 8)

Oh well, time to get the tape measure out :D

Cheers

PS Used exiftool to catalog my mp3 files (on Linux so can't use MediaMonkey)! Absolutely brilliant tool - many thanks!
