So i got this shiny new R7, and wanted to see how it behaved with my old Sigma 120-400.
Like all modern mirrorless, it has a very powerful autofocus, and when it is told that the subject is a human or an animal, it tries to identify the eye and sets the focus on it.
To test this, I go to one of the ponds in the Bois de Boulogne where flocks of seagulls and Canada geese dwell, and spend some time shooting the birds.
Then I see a dog running towards me, and welcoming the change of subject, I aim the camera, half-press the shutter, and see the little blue square wander a bit before locking on one of the dog’s eyes. Then suddenly the dog turns around, and the little blue square wanders a bit, … and locks on the dog’s butthole.
