Leaves of trees look blurry.
I'm encountering this problem when dealing with foliage, note in the attached image.

Looks like heavy denoising?

I think you are right, I'm using Nvidia denoiser, with 1.0 radius, which one do you recommend?

I usually keep it to 0.5, and I prefer to use Corona HQ... but I have no info on which denoiser does what, or why...

Most helpful would be to render longer and use less agressive denoiser strength. I theory Corona HQ denoiser should give you best results, but some people swear by Intel, or Nvidia AI denoisers. You can test render on small area of interest and compare result by yourself to see which denoiser works best in your scene.

Thank you "aaouviz"
Thank you "romullus"

It works, sometimes, denoising makes details less clear, especially nvidia denoiser.. here is the result for 2 renders of mine, in the attachment file
