Spend another morning for test one of the most difficult photograph objects, swift and swallow.
*** I will updating all the swift AF test here.
There are some setting that I change for this fast moving object which I think it may affect the performance
CANON R3, CANON EF 500mm F4 IS2, EF 1.4x TC III
AF area (whole sensor)
AFC, eye-control AF off
Drive mode: H (15fps) and H+ (30fps)
AI Servo (AF-C)
cRAW and use DPP straight convert to JPEG and resize.
No CROP
Len set to >10m which anything near than 10m will not be focus
no feeding, no fix location/direction for the bird. Everything here just a bird flying and I just point my Len direction and lets the camera lock the focus (on bird) and track by following the flying direction
few test, trying to show
i. near object
ii. far object
iii. flying at same Background (Green, sky)
iv. flying cross various background
– can see below, the birds will flying crossing sky, water surface, green etc
