Sharp render

[fa2020]

Hi guys,
Is there any way to get a sharp result using Corona? Recently, I tried to render a sculpture using backplate and HDRI. All thigs were good else than the sharpness. All buildings that were far away from the sculpture were sharper than the sculpture while I used no DOF. All those buildings were in backplate. I tried to decrease tent amount from 2 to 1 but it resulted in jaggy edges. The only way I found was to use sculpture's alpha as a mask in Photoshop and sharpen the sculpture only in order to match it with the rest of the backplate. And you know that sharpening using photoshop changes the image quality, especially it's edges.
I want to get such a sharp result using Corona. Is it possible?
Please help me.
Thanks.

Please add images for the said problem so we can tell what is wrong.

Sharpening should always be the last step in post processing. If you think that sharpening in photoshop deteriorates your image, then you should know that applying sharpening in VFB and then doing post process elswhere, would be much worse.

Nevertheless, it still would be nice to have basic sharpening controls in Corona, for those cases where external post processing is not needed.

An image would be really helpful, because I also have problem imagining this situation. :)
