Greetings,

What camera and what lens are you using?

None of my bodies or lenses I've ever owned had trough like indentions like the contacts in your photo.  The next question I'll ask is are you using some type of adapter or TC on this lens currently or previously?  If so, which?  You'd have to put a lot of pressure on a lens contact to dent it like that

What lens is this, and what camera body? Is there any other device between lens and body?

Canon 4000d and sigma 150-500 ef no adapter and i dont put much pressure on the lens

Well, the lens IS damaged, for sure. If this is the way you bought it, you got taken.

Greetings ,

As you can see we both started asking the same questions.  This condition is not a normal occurrence and this lens does appear to have seen some neglect or abuse.  

If returning the lens is an option I would pursue that.  If not, the lens can likely be repaired by Canon.  Start by registering the lens in your My Canon account.  From there, you can initiate a repair request.
