Hello all,
I have a Canon 6D Mark 2 (Roughly 1.25 years old) and an EF100-400 f/4.5-5.6 is ii usm lens (only 5 months old), and I am having issues with focusing on aircraft, specifically in the air.
The settings that I often use are:
- AI-SERVO focus (I have used ONE-SHOT, however the result is still the same).
- 1 point auto focus (centred).
- ISO 200.
- f/9-10.
- Shutter speed of between 1/640 and 1/1000.
The focus is worst on side-on shots of aircraft, and the focus is often sharp on the tail section and body, whereas the nose is often extremely soft.
I previously used a EF70-300 lens and did not have issues with auto-focus.
Would anyone who is using similar equipment be able to share what settings they use, or any suggestions about what may be causing this auto-focus issue?
Many thanks, Jack.
