I've been wondering about the minimum focus distance of the 4S for a while now. Apple is curiously silent on the subject, for such a critical spec. Very curiously silent to my mind, as The Jobs was a king hell detail freak. Made me wonder. On the net one finds a lot of categorical statements - nonetheless using the word "about" - that go from 2" to a foot (or so). No pictures, of course, or objective standard of just what "in focus" was. Made me wonder even more . . .
So I scratched that itch tonight.
I set up my highly sophisticated test lab (my desktop) and found an ordinary business card with very crisp printing when viewed through a 10x loupe. Plugged the earbud into the 'phone for remote (vibration free) shutter actuation. Put some adequate light on the subject.
Then I took shots at 6, 8, 10, 12, 14, and 16 measured inches. All shots were taken with 645PROMkII and are completely unprocessed TIFF. Point of focus for all shots was the name "Nigel". I then took a detail crop of the lettering from each pic in an extravagance of pixel peeping.
These were the results:
6" -
8" -
10" -
12" -
14" -
From 14" and on up I'd say that the pics - even with my poor old worn out eyes - were in reasonable focus. Below 14"? I'd say not.
So . . . either I have an out- of- spec camera or . . . The chatter about minimum focus of the 4S is urban myth.
Either way, I now know what my camera will do, and won't, which is all that mattered to me in the first place.
I'd be curious what other 4S shooters on this forum consider min focus on their own cameras.
