Panasonic 100-400 Soft at the long end
1

I bought Panasonic 100-400 for bif and on my first trip in the field I found that at  400mm it was quite soft even at 1/2500th: I am quite sure that it was not due to lens fault but my shaky hands or lens vibration because my inferior (or cheaper) 75-300 can produce sharper image than those at 1/1600 and also I struggled with my 75-300 quite a while before I capture stable images(I have very unstable hand DNA).

So, I will try to practice and apply best settings to get sharper images for bif.

My current setting is anti-shock (diamond with zero second delay), normally at shutter speed 1/1600 or 1/2000, IS auto, sequential L (7-10 fps), all focus points(121) used for bif, af limiter (3m-infinity or 4m-99m), CAF (no tracking), CAF mode 2 or 3

my thinking is

change anti-shock diamond to silence mode

turn off both IBIS and lens OIS

1/1600 or 1/2000 should be okay for big birds such as heron and so will not increase shutter speed...

shoot at 375mm or shorter focal length until I get used to the lens....

Any suggestion to change my settings for improvement?

Thank you in advance.
