The EF 200mm f/2.8L II USM telephoto lens was utilized for the above sequence shots of a Perodua Kancil car that was among those that took part in the opening round of the Peninsular 2001 Rally Tour, and a perfect test target for the EOS 30's predictive focus tracking ability via ECF in AI Servo AF mode. The final shot in the above sequence was shot in another stage when the car went across a puddle and caused the splashing effect, which was great for rally photos. I decided to keep the car in the center of the frame and used the ECF to track its movements. As long as I kept looking at the car, the EOS 30's AF system would not stray off from it and neither would it accidentally refocus on other subjects that might intrude into the frame and subject matter. For example, this first shot from the sequence of another car (below) was partially blocked by a rubber tree but I had the ECF feature locked on the bonnet via the center AF point. If I had looked at the AF point next to the center one, the camera would have shifted focus to the tree instead. However, as the ECF reacts in real-time where AI Servo AF mode is concerned, any wrong target that the camera may have accidentally locked onto can be instantly corrected simply by looking back at the right subject matter via the appropriate AF point.
As can be seen from the above sequence, the exposure on the car and the overall scene were correctly obtained by the EOS 30's 35-zone Evaluative metering. There was no incorrect exposure even when the car came past an opening where the sunlight was able to shine through the rubber estate plantation. Of course, what was already in deep shadows were recorded as they were on film. A fill-in flash would probably have helped in getting more details out of the shadow areas but that won't show how the camera's metering system was able to cope with situation like this. << Back to Main . 1 . 2 . 3 . 4 . |
