Blur photos

[vasos]

Hi guys, I am facing the following problem with my 100-400 is ii. While in still photography the photos are almost perfect and sharp in action shots and especially when photographing flying birds 99% of photos are blur. I have been using this lens for a long time and noticed that these results are recent. I had been using the 7D MK2 and the 5D MK4 with no issues but I don't know what happened and i get blur photos with both cameras and R5 as well. Can anyone experienced same problem and give me some help. Thanks all.

What settings are you using. Can you please post an example picture in the forum with metadata attached. What mode are you shooting in. Are you using IS (Image Stabilization) or are you on a tripod.
