Why is my render blurry? In the camera settings I didn't set anything regarding Depth of Field but it is still really blurry.

 

I have bump maps included in the sofa, curtains, floor but none is visible because of the blurriness. So I thought maybe it is bc of the distance of the camera but that didn't work as well. Samples are at 1048.
To explain the depth of field, make sure you have the right camera set as active.

Also, the missing detail in your objects could be the result of the denoiser.
