[FONT="]I came across an old Greenspun.com thread from ‘01 that touches on the AF characteristics of the camera.[/FONT]

[FONT="]In particular the comment/observation made by Kwen Wan – [/FONT]
[FONT="]“One thing I did notice (on my T3) is that the autofocus area is approximately 5 ovals wide (if you take the autofocus 'oval' and lay them out 5 times) and it prevents my T3 from focusing through a gap in the door which is half open -if I sit stand about 2 metres back from it. (by the way, are the U.S. T3 distance scales in feet?). If I take a vertical shot the autofocus area doesn't clip the edges of the door and focuses through into the distance. [/FONT]
[FONT="]The above is the source of the problems I have with close up focusing at wide apertures. Having analysed the 'duff shots' one photo is of my son at the table with a basket from which he is eating. The shot is vertical and instead of the focus on his face, my T3 has turned it's attention on the basket. Although I positioned the autofocus target on his face the width of the autofocus area when the camera was vertical must have clipped the basket in front of him and rendered that sharply instead...hmmm. Of course if it was an outdoor shot with plenty of sun the camera would have gone to a smaller aperture and depth of focus wouldn't have been so critical. [/FONT]
[FONT="]So it's probably 'operator error' more than anything, and stems from the fact that Contax did not represent accurately the width of the autofocus area in the viewfinder. Some other brands physically show the width of their multipoint autofocus.”[/FONT]
[FONT="]I find the above observation to be consistent with the way that my camera responds with respect to its AF operation. [/FONT]
[FONT="]If you want very accurate SPOT FOCUS then use the AFL feature. The standard autofocus area is much wider than the focus patch indicator in the VF would suggest.[/FONT]
[FONT="]Personally, I use manual/scale focus 90% of the time with this camera. If I need to establish a different focus distance quickly while out and about, I’ll use the AFL button which acts as an instant SPOT FOCUS override for my preprogrammed manual focus distance.[/FONT]
