EOS 5D Mark IV blurry photos in continuous shooting, AF tends to miss a lot

[Haan]

Hi everyone,

Hope someone can help or probably know this issue. So using sigma 85, 1.4 and sigma art 50 1.4 for portrait work. I have noticed two things.

1. When I use continuous, take 3 photos, I have noticed that somehow the images are sometimes blurry or shaken (with and without trypod)

2. I noticed that autofocus tends to miss a lot lately. Is this a firmware thing?

Have a great day and thanks in advance for any reply

Regards, Haan
