A quick post regarding the performance of the new AF system on the Canon 7D.
I wanted a combined test in this shutter squeeze.
Camera: 7D
Lens: 16-35 f2.8 L II
ISO: 1600
Ai Servo with central AF point selected
8fps
Sequence of 13 images.
It is important here to note that the squeeze followed the moving subject from the foreground (white T-shirt) and change of subject to follow the background subject black T-shirt)
In this sequence is combined the Canon’s new AF system in Ai Servo mode combined with high ISO, panning, changing of subject and changing of contrast on the zone of focus.
Images shot in JPEG mode from the camera. Cropped with Adobe camera raw with no additional ingredients (no sharpening, no color correction …)
The plan was walk around in Floriade with a model for a few outdoor shots but the model called in sick so …
This explains why I had the 16-35 f2.8 L II instead of another more exotic lens for “sport” photography.
A more intensive and extreme test of the new Canon AF system is coming shortly (I did the tests and am in the process of putting it online).
Consider this one as a teaser![]()
