Hi,
I have a z712 which allows 4 choices wrt focusing. AF/Macro/Manual/ and Infinity. Here's how the manual describes them:
Working range:
Auto: 19.7 in. (50 cm)–infinity @ wide; 47.2 in. (120 cm)–infinity @ telephoto
Close-up/Macro: 4.7–23.7 in. (12–60cm) @ wide; 7.9–51.2 in. (60–130 cm) @ telephoto
If I read this right, it defines infinity as 50cm wide open, and 120cm at full telephoto. Macro and manual I get; but I'm not sure what the difference between AF and Infinity is; except perhaps that AF doesn't focus until you half depress the shutter button.
Does anyone have a better handle on this?
Thanks,
..... john
