Hi everyone! I recently bought a very expensive Sony AR7V with a 200-400mm lens and attached it to a harness which failed.

It ended up dropping my camera about 2ft off the floor. Yikes I know. I checked it thoroughly after and found no obvious physical defects. I even took to a camera store to check but didnt' have time for a full analysis before leaving for my trip. I noticed when taking a picture of some birds, weird striated textures came up in the background. Is this the result of a damaged lens? Or is it something else?

Would really appreciate some help cause I'm like.. panicking!

To note:
Stabilizer is on
Some of these pictures had high shutter speed

Metering: Tracking (S),
Subject Recognition: Birds

I have done photography before.
Thank you!

I think you mean one of the Sony or Sigma 100-400mm lenses. I don't have either lens.

Regarding photo #1. I see circumferential markings on the gray pot, or maybe it's a pedestal, that's part of the decorative features. Are you seeing something else?

Regarding photos #2 & #3. I do see some "double bokeh". A lot of my zoom lenses do this with similar scenes. Does this effect happen in plainer scenes without all these grassy plants?

Take a look at this thread. DPR member Tom Axford demonstrates how something in the foreground can affect the bokeh of the background.

Are you looking at those photos on a phone by any chance ?

All 3 images have the same weird striated pattern sloping down from the left to the right and more visible on the right side.

Are you taking photos through a window?

Do you have a filter on the lens ?
 
I'm on my computer looking at the sample full-sized, but if you see odd striations I believe you.
 
Could be whats known as "nervous bokeh", which is caused by the IBIS system.

Turn the stabilizer off, see if it looks the same.
