With the help canon EOS 7D Mark II and several different Canon EF and EF-S lenses, canon USA recently shot a short story “cello”.
The Digital Picture pointed one feature that is quiet beneficial for the videographers.
“While Movie Servo AF isn’t exactly new, the EOS 7D Mark II brings a very important feature to the party – the ability to customize focus speed and responsiveness while shooting video. Take a look at the focus pull at the 2:13 mark; it’s absolutely beautiful. The ability to slow down the camera’s focus transition allowed for a very natural-looking focus pull.”
