About the ECF feature, most professionals say they don't like it and never use it. As for the amateurs, some have heap high praises on it all the way wbile others are having a hard time getting their EOS-3s to focus where they are looking at. As for me, the camera I have been using for this issue refused to focus on any of the nearest off-center subject as it tends to focus on the background even though its 45-point Area AF ellipse was switched on all the time. The EOS-3 used for this issue does not belong to me but one ofthe demonstration units used by Canon Malaysia for its ongoing Camera Roadshows around the country. Its erratic automatic multi AF point selection feature could have been due to the numerous testing (which can be subjected to abuse) by promoters and show visitors. Although the automatic selection did not work well with the EOS-3 I have, its ECF feature, did. Of course, I do encounter one problem with the ECF - it reacts very well to my left eye but doesn't seem to be that efflcient with my right eye despite having calibrated both of them on two different ECF channels. Having said that, the ECF worked well in all conditions, whether in bright daytime, low light or night-time condition. It should be noted that the effectiveness of the ECF has nothing to do with the lighting conditions but the user's eye and its reactions. When used with the 21-zone Evaluative metering, sometimes the exposure can be disastrous as the emphasis is based on which AF point is locking onto the picture area. The photo (below, left) was recorded correctly when the ECF was used to lock onto the buildings. See the difference when the ECP was used on the skies instead. The buildings became underexposed. The same applied to the two photos of the early morning sunlight shining through the clouds. ECF locked onto the buildings ECF locked onto the bright skies     ECF locked onto the darker clouds on the left ECF locked onto the brighter clouds on the right For scenes with average brightness, like these two photos of the white clouds against the blue skies, the ECF/Evaluative combination is much easier since there will be no significant difference in exposure value in any area where your eye is used to enable the E0S-3 to lock focus on. No exposure problem with this Slanted the camera angle for fun     Balance between highlights and shadow area Another balance exposure with Evaluative Likewise, the brightly-lit highlight area of the apartment buildings in the middle and surrounded by those in shadows, is another example of how well the ECF can be used to get the exposure right. In this case, effective AF point was in the middle, between the two contrasting areas. For the photo of the bus stop, the ECF was locked onto the group of people seated on the bottom right, with excellent exposure despite the brighter background. << Back to Main . 1 . 2 . 3 . 4 . 5 . 6 .
