You can change to any renderer of your choice. Just change the materials also.
Corona is a very good render for Architecture and product visualization. It give you a high quality photo realistic result right out of the box. But like Arnold render noise is the big problem. You need to wait a long time in order to get a smooth render. They introduced a new noise reducing algorithm which removes noise after rendering.
Corona for Cinema 4d is still under development. But the alpha release is pretty stable with most features built in. You can get a fully functional copy of Corona render free from their website.
Here is the test render.
It took almost ten minute per frame for 50 samples. It is affordable for my laptop with i7 running at 1.74 GHz speed.
