What are you going to be filming? Will you be on the go? Or static in the studio?
As a preferred choice, RED Camera offers unprecedented configurability and quality for outdoor and indoor shooting.
My choice for best camera:
With the right base camera, you can experiment with more low-fi attachments like your phone.
For more details check out specs and compare cameras at Camera Culture.
A good lens is likely to outlive your camera body because good optics are not prone to obsolescence like your fast advancing electronic hardware.
My go to lenses:
Depending on your subject matter and your location, you may want to consider at least 2 lenses.
