I was walking towards the jetty at Kumbhargaon near Bhigwan in India to photograph birds. It would be the day when I will use the 1.4 extender for the first time—It’s a Canon 1.4 extender Mark III on a Canon 100-400 Mark II lens. Now my 400 millimeter 5.6 lens is a 560 F8 lens, 1 stop down.
I will be able to autofocus at F8 on a Canon 7D Mark II body using the centre point and four assist points.
Now I know what you’re thinking—it’s a bad idea to use an extender on this lens—but I have a plan. I’m going to photograph birds in flight against the bright blue sky when the sun’s out. So that way I won’t need a ridiculously high ISO for a fast shutter speed.
I’ve never done this before so I’m looking forward to seeing the results; so let’s watch the video.
I have more wildlife vlogs on my Youtube Channel, The Open Image.
