I think my challenges are:

  1. Camera settings

  2. AF technique

  3. Tracking fast-moving (sets of) terns

Challenge 1

Focus right on bird, blurry images.

Challenge 2

Tern flies in, AF on tern, blurry result.

Challenge 3

Tern hovering in canopy, AF on tern, blurry images.

Challenge 4

Small group of terns, some in focus, some not.

Challenge 5

Coming in (sometimes fast) over the trees.

Challenge 6

Against blue sky: no problems with Canon 80D 9-point focus, but R5 often cannot find focus point.

Challenge 7

“Hovering” terns in tree canopy.

Challenge 8

Terns flying straight in towards camera.

Challenge 9

Cannot get focus on stationary terns.
