Usually I don’t participate in discussions here but it is amazing how how simple questions about Premiere can go into long thread W/O answer (not only on this forum).
I’m not PP editor primarily.

First I’m not sure how you define After Effects, Cinema 4D as a mid-level stuff. After Effects is a industry standard for motion graphics. No, it is not compositing “one shoot based” tool, but again you can do much more serious compositing in AE than you can do motion graphics in Nuke / Fusion 🙂 Cinema 4D is currently the most used 3D application for motion graphics and together with Body Paint very much used for feature films.

Now back to the subject.
– Yes, you can edit DPX, XDCAM, DSLR (and many more formats, RED, etc.) without transcoding. Performance will depend from your system
– Yes you can export CMX3600 that will work with Resolve (also with Speedgrade and others). Friend of my have just finished grading of the feature film that way (shoot with RED)
– For VFX guys (Nuke / Fusion) you will probably always export DPX sequence, and yes PP can do that.
