各位Ching:
如題,我記得之前有Ching曾經post過上來,有一網站可計算出,不同光圈,不同焦距,可計算出景深有多大,但現在找不到這post,Ching們可幫忙知道嗎?
Thanks

And one interesting piece of information for you.........

For same Apeture, with same magnification on film or sensor, the same the Depth of field

eg. DOF of 50mm F4 at 5feet = DOF of 100mm F4 at 10feet = DOF of 200mm F4 at 20feet

# note that the above would give the same magnification to image.
