What SLR camera and lens should I choose when shooting portraits of car models?

The clarity you mentioned requires post-production.

Because few models’ skin can withstand the test of Baiwei’s lens...

30/1.4+50/1.8.

You don’t have to buy a very good camera body, the lens can be expanded later.

30/1.4 is suitable for shooting environmental portraits.

50/1.8 is suitable for shooting large heads.

If the focal length is longer, the distance will exceed 2-5 meters.

But one problem is that Canon photos require post-processing.
