Art Aldrich and his Canon C300 sporting a Canon 400mm prime at the Farnsborough Air Show.
I recently had my trusty C300 upgraded by Canon for the Dual Pixel Autofocus firmware. This feature added live continuous auto-focusing of Canon EF lenses, and is a $500 factory installed firmware update.
Shortly after the update, I had a shoot that would put this feature to the test. The location was just outside of London, at the Farnsborough International Air Show. I wanted to shoot some of the planes that would fly that day, and my lens choice was the Canon 400mm F4 prime, which I rented from the good folks at Lens Pro To Go.
The autofocus works on a section of center frame, and can be locked via a user button, or disabled altogether. Read the details here.
I shot this clip with 3 stops of ND, at ISO 320, and an aperture of f5.6. Take a look for yourself.
Needless to say, this would be a very tricky focus pull for a single operator to pull off.
